Observatory & Equipment
Also take a look at past years for interesting images and projects.I like to call my Images "Now & Laters". Observe Now and Share Later.
Images are made from a live stack of many images usually around 3 seconds for each frame. The stack itself is around 3 Minutes in duration.A dark frame is removed for each frame during the live stack.Minimal processing is performed during the live stack. No post processing is performed on the final image.These images can also be browsed in the object image page.Clicking on an image will open the full size image in another page or a GalleryCheck back often as I work on projects in the observatory

Local Astronomical Seeing and Weather Overview
The jet stream does not come down into the east coast of Florida often except during periods of El Nino which has been shown to cause a lower southern jet stream to dominate from the Pacific all the way to Florida and into the Atlantic. When this occurs astronomical seeing can be effected as with a front passage.
Periods of La Nina also effects conditions and are known to be associated with calmer upper winds with no jet stream. The jet stream is easily tracked these days with many resources. Unfortunately this calming causes there to be very little shear allowing Atlantic storms to gain strength and threaten landfall. Occasionally an "Omega Block" as it has been dubbed due to the shape when the jet stream is forced around the top of a high pressure system that is between two low pressure systems over the CONUS can bring fair high pressure weather to the region or bring the jet stream into the region. The seeing will be affected as well. The presence of upper level thin clouds and pollution from aircraft condensation trails can increase heavily and helps tell the story.
African dust that traveled the Atlantic onto Florida at times can also effect on the seeing. This is not a new phenomenon but has started to be well tracked the last few years and its arivial can be predicted.
During the winter season prevailing winds are most often from the northwest and are cooler and less humid. Humidity averages 50 to 70 percent. Temperatures average 40 to 80 degrees. Unusually cold temperatures can occur infrequently dropping into the upper 20's at night usually after the passage of a front. This usually does not last long at all. Also, during this season frontal systems can pass through leaving transparent conditions. Seeing can be below average for a short period after it has moved through. Usually there are conflicting wind patterns after a frontal passage. Before the frontal passage seeing also can be above average.
During the late spring, summer and early fall, prevailing winds are from the south or southeast. Humidity will be on average 70 to 90 percent. Heavy dew at night is daily. Temperatures average 70 to 98 degrees. Frequently, in late afternoon cool moist air over the Atlantic moves onto the coastline eastward into the interior that has been heating from the day. This local phenomenon is called a "Sea Breeze". As the sea breeze moves in it clears and stabilizes the air usually up to a few miles inland from the coast. Inland the moist sea breeze meets the warmer interior air, water vapor rises often causing rapid developing thunderstorms with frequent lightning that can move in from the west. Often, the storms will stay a few miles inland off the coastline due to the same sea breeze depending on how strong it is. If this occurs the seeing will be good. At times this is a daily pattern and the sea breeze can be seen on radar forming and moving onto the coastline as a wall. Often, during the summer, clear skies with good seeing occur a few hours before dawn.
MEO Lightning and Storm Mitigation
To date I have installed a utilities whole house surge protection system that included the observatory. The observatory has its own full cutoff box & breaker power panel with power and data cables trenched to the building. Ethernet cables have an active Gigabit gas discharge tube lightning suppressor installed at the observatory. Additionally, the instrument trolley has a full size backup and surge suppressor downline of the active protection for Ethernet & power and also strip surge protection for all components on the instrument trolley. That being said, when weather predictions include lightning I unplug the Ethernet, USB and 110 cables from the instrument trolley.
The observatory building itself is metal and grounded from the metal sides to 15 ground anchors and an additional copper ground rod and instruments and computers are isolated from it. I believe this allows a cage of protection not had in composite dome type observatories. This type of protection would not be a great idea if I was using an in-ground pier for the mount and telescope as that allows a path back up to the equipment from the ground. I am not installing lightning rods or a lightning pole nearby to attract leaders away from the observatory into the ground which I believe would make things worse by increasing the odds of a hit and not increasing protection. If a strike nearby occurs it could allow current to come back up the building groundings but should not allow damage as it will also have a path back out and the equipment is isolated. If a direct strike occurs it has a path out and away from the equipment.
As a sailor I understand the cone of protection afforded a sailboat with keel groundings to the mast and steering pedestal. I also understand that a nearby strike can come up through this type system as well to you so you must isolate yourself from the metal in the boat. This is the same theory I have used in my lightning mitigation for the observatory. I have had first hand experience a few summers ago at my work building. We had a direct strike to our building and cables as we were working. It was witnessed from an employee leaving in her car as it struck the metal roof. We were engulfed in a colorful glow. Inside, it traveled through the phone lines and damaged two computers and a few phones. It also damaged Ethernet routers and damaged a large screen television. One employee was on the phone at the time out of the many phones. She was frozen in a stunned state and I had to knock the phone out of her hand. Luckily no one was injured but I can tell you we are now more aware when weather is moving in after that. At one point we had cordless phones which was great for that problem but the type of business requires security so they are no longer allowed. We do not answer when under lightning. The same type of damage occurred in this instance as I have seen with observatories.
Florida also has hurricanes and protection from storm damage must also be addressed. The observatory building is rated for 140 MPH winds and I have installed 9 additional ground anchors deeper than code required. I have also installed storm shutters for the windows, roll door and additional door close bolts for the main entrance. Computers and monitors can be removed quickly and the mount and scope can be removed and stored if the storm warrants it. The Observatory has already weatherd a category two storm with no damage or problems.
MEO Observatory Design Pros & Cons
Observatory & Astronomical Imaging System (AIS)
Pros:
- Hurricane approved structure.- Code approved structure without custom engineering approval.- Complete engineering drawings available for code approval.- A very quick setup time roll out / roll in.- AIS can be monitored and temperature matched for the outside temperature estimated for the nights observation run.- Ability for telescope trolley & AIS to reach ambient temperature quickly and have no heat retaining material under the mount.- Climate controlled room for me! (Have you seen the bugs in Florida! Not to mention the heat!) Also allows year around use.- Storage of the telescope and systems in a climate controlled structure for year round use.- Ability to retain an acceptable polar alignment.- Trolley system isolated from vibrations from the structure and the observer.- Trolley system isolates the AIS from local or ground seeing by being removed from any structure while retaining polar alignment.- Lower horizon altitude limit with no structure obstructions.- Observer stays inside year around for bug free climate controlled comfort.Cons:
- AIS is susceptible to heavy wind.- AIS susceptible to direct local light pollution.- Precise arc second polar alignment must be adjusted at each use if needed.- Sky is not visible from inside the structure. an all sky camera is necessary.- Dew has to be controlled.- Not a classical observatory structure.- When visually observing some scope positions can be awkward.Mind's Eye Observatory 2018 to present
Present Observatory Structure and Facts:
The present structure was a gift from my parents when my father passed away. It is a hurricane approved, code approved structure. It is now in the same location as my temporary observatory. At first I contemplated an opening roof modification but ultimately discarded that idea because of the number of problems associated with that type of design and the end result wouldn't really fit my needs.After much contemplation I designed a trolley system with tracks to allow the telescope mount with all equipment to be rolled out and in for climate controlled storage. Using this design also allows the observatory structure to be separate from the mount and is positioned to the north of the mount, thus minimizing thermal waves that affect local seeing conditions for the telescope. This separation also minimizes vibrations from the people using the observatory and the instruments.
During good weather I can use the system with eyepieces, if desired. During other times of the year I can roll out and use the system from inside the air-conditioned / heated room using integrated video cameras or CMOS cameras. A cooled / heated bug free room was essential if I was going to build a permanent observatory. This has greatly increased my observing time.
Moving the trolley, cables & power in and out is very easy. The roll out is usually performed in less than 10 minutes (maybe a little longer for roll in with a late night stupor!) I use a simple checklist so I don't miss anything important when working with an astronomy hangover!
Electricity to the observatory is supplied from the house mains trenched from the north corner of the residence and lighting is supplied by LED white and red lights installed inside.Regulation of temperature and humidity is supplied by a self resetting air conditioner and a dehumidifier.Security is supplied by motion LED flood lights on all sides. A security motion alarm is also wired into the building that alerts me and also sounds a 120 decibel speaker horn. Testing proved painful to my ears to the point that I hate testing it! Surveillance is provided by a KASA wi-fi cam that allows me to monitor at any time and alerts me if any movement occurs around the observatory and surrounding area. It will also alert me of a power outage. Since the structure doesn't stand out or attract attention like a classic dome tends to, I believe the equipment's safety is increased.
Lightning protection is accomplished by a copper grounding rod at the north side augmented by a tower on the north east corner supplying a cone of protection. The building's natural metal siding also helps protect the equipment from discharge paths unlike fiberglass enclosures. Summer lightning in my area can be frequent and violent. When the trolley is in storage inside the building all cables and power are disconnected, helping to minimize any stray current from a strike and help protect the sensitive electronics and instruments.
Installed inside is a dedicated desk with a multi-monitor display for operation of the observatory. Increasingly I find I use my hard copy reference material and charts less and rely on computer charts and digital copies of favorite books and references when observing and planning.
When operating from inside, visual and audible cues on the mount performance are lost so I employ a camera outside mounted on the trolley with a microphone linked to a LCD Monitor to help replace these important cues. When operating close to the horizon or the meridian I take extra caution monitoring mount performance to avoid problems and take note of any irregularities when slewing. It also allows keeping an eye on cable management.
Camera focusing is controlled via a stepper motor system and is done with a bahtinov mask. One mask fits both telescopes and can be performed quickly via a dedicated mini monitor at the mount or from inside the cool room. Alternately i can implor using the FMHM multi-Star focus routine in Sharpcap to autofocus without a mask.
Trolley Construction:
The trolley is constructed of wood with five heavy duty wheels per side. Handles have been installed on all sides to allow easy roll in and out.leg Bumpers have been installed on all sides as well.
I believe highly about wood construction over using strictly metal in respect to dynamic vibrations. This has proven true with the trolley vibrations being easily dampened.
Trolley Features:
The 110 volt power is supplied by a mobile cord routed away from other cables to minimize electronic interference.A converter allows for 12 volt power and is supplied to a buss I built.
Cable management problems are minimized by utilizing triple 30' active USB cables with hub's to operate the cameras, focusers and frame grabbers.
The mount is operated via wireless wi-fi control with la dedicated tower PC that also controls the imaging. A Samsung phone as used as a wireless hand control. I am not a huge fan of wireless systems due to connectivity problems that can come up just when you are deep in observing but the wi-fi mount control has proven to be flawless. If problems ever arise I will revert to an optional cable control.
The Losmandy G11 is mounted to the trolley and retained by a cable and turnbuckle system from the mount center. vibration isolation pads are installed under each leg.
The Losmandy G11 head has a safety bolt installed to hinder turning in the quick locks.
An all sky camera is installed on a mast "The Selfie Stick" at the front of the trolley (north side of mount) and does not interfere with scope positioning. This allows me to monitor sky conditions while the scope is in use.
Polar alignment has proven to be quickly repeatable even with the mobile nature of the design. Polar alignment importance was a trade off. I do not need to adjust it very often.
A simple web camera allows me to see what the trolley is up to during slews when the roll door is closed and is mounted low to avoid IR light interference with the telescope imager. A color selectable LED flood light is installed on the trolley. It is operated via a remote as well as a color selectable LED array under the trolley to aid in working around the mount when needed. Portable red and white flashlights are mounted on the telescope trolley for handy quick access if needed.
The trolley also serves as a convenient storage platform for eyepieces, filters and other equipment. The mount legs have industrial female Velcro applied in bands for quick placement of hand pads and equipment.
Trolley Track Construction:
The trolley tracks are constructed of wood, leveled and supported by post blocks. The design allows the trolley to roll restrained side to side and is not connected to the building to minimize vibrations. The tracks have much less heat sinking structure compared to a deck or concrete pad and are additionally over grass that doesn't hold heat from the day.I have installed ground anchors with turnbuckles but I don't think they were really necessary. The tracks can easily be picked up and moved into the building if necessary for a hurricane threat or maintenance.
The trolley rails only require a yearly cleaning and paint.
Construction Philosophy
Construction Philosophy
My observing style, goals and constraints have driven my observatory construction and setup to its present shape. It is optimized for live real time video viewing with ease of start up and shutdown. My equipment is not state of the art or top of what is available these days. Its is nice equipment none the less. Getting outside using and optimizing what you have is what it's all about. Learning the sky and equipment operation is a lifetime Journey to be enjoyed now not when you can acquire the perfect equipment.Observatory Equipment & Specifications
