Re: An Eagle for the UC18
Very nice! I like the Com Block Diagram!
You're the first one ever to build a changing mechanism for my FilterSlide set up. Congratulations, it looks like it's working great!

All,
Just thought I describe the configuration details of making a remote obsession UC18.
Putting an Intel I3 on your Obsession might seem a bit extravagant, but Primaluce offers a line of computers targeted at the Telescope market.
Start with the power that is available in remote locations:? battery power.? The Eagle4S that I purchased will use up to 1 amp at 12 volts.
My 55 amp hour battery is an AGM type so I outfitted it with a voltage regulator to maintain 13.8 volts until it runs out of power (about 11 hours driving my rig).
The Obsession gets all of the power through the powered ground board with a pair of rotating contacts.
The Eagle4S has:
1. Power distribution (2 ports that can provide up to 8 amps and 2 ports that can provide up to 3 amps).? There are also 3 ports that have programmable voltage output for dew heaters and fans etc.
2. an onboard SQM that measures the sky quality in a 5 degree FOV of the sky where the Obsession is pointing.? When I record my observations, I like to know the quality of the sky and record that value in a database.
3. an onboard GPS to know time and location of the observations.
4. 8 GB of DDR3 memory to run all my software:
? ? ? a. Stellarium to slew my obsession and help me plan my evening targets
? ? ? b. Pegasus control for my fancy USB hub (operates on 12 volts) that can run each port with a different protocol (USB1 - USB3) at the same time
? ? ?c. My own software written in Visual Basic to change filters, and collect data from all the sensors and Argo Navis and weather station
? ? ?d. Focus motor software control with temperature compensation
? ? ?e. and most importantly, Eagle Manager that allows remote control of the entire system.? The Eable Manager supports a web query so you can ask the Eagle to report all of it's sensor measurements.
A custom wooden bracket mounts the eagle4S where the wheelbarrow handles normally attach on the side opposite the alt encoder mount and points the SQM in the direction of the telescope target.
Argo Navis is tightly integrated with the ServoCat makes remote slewing possible after a 2 star alignment and setting the mode to "From Planetarium".
When I slew to the next target (from my recliner) the ServoCAT servos can use up to 4 amps (I normally see only a couple amps going to the servos).
At the end of the observation session, I copy all the new directories on the Eagle SSD drive to my NAS for post processing at a later date including the database updates that include all the "meta" data (about 50 fields) from the SQM, GPS, Argo Navis metrics,
weather station parameters, battery monitor at the time of each image capture.
Post processing will include importing all the harvested data into a database.

Hi all,

The Argo Navis helped me find all those fun objects. ?Describing my views to my friends and family was not very satisfying. <848B6C9C-6708-49FA-B705-CC6770994D67.jpeg> <EA2C4E81-F9A7-4A22-BD00-E393C10426CA.jpeg> <3F14CA69-757A-4F39-8F51-4C714365D891.jpeg> <1D2CB95F-E620-433F-837D-6CC42E6CCAB9.jpeg>

No tracking required (for bright objects).

I added an Eagle4S to my telescope so I could remotely and wirelessly observe on my big screen TV while the telescope remained outside on my deck.

Re: Slippery azimuth movement
¡ and one way that bent pins occur, especially on 8p8c Telecom modular female connectors (aka RJ-45) is by inserting a smaller male connector such as the 4p4c (RG-handset) or 6p4c (RG-11) into the 8p8c connector. ?So, be careful about connecting your equipment. ?It¡¯s easy to grab the wrong cable when setting up in the dark.?

Re: Slippery azimuth movement
One idea from past experiences: If you set up on grass and not on some protective matting or concrete, grass can clog the gnarled knob that rests against the wooden ground board, thus making it slip and even wear into the wooden board. If that is the case, a thick rubber floor mat from a box store will prevent that issue from happening. I do cut a hole to allow the power cord to run under the matting to its plug.
However, there may be other issues that need checking.

Slippery azimuth movement
I have since 2004 and Obsession 18" with Servocat and AN which is a fantastic scope.
However I have a little issue right now: the azimuth movement (in goto mode) is on some places "slippery".
What could be the reason? Could it be the ground board is worn out on those places (I don't see anything "wrong" there) ,
or could it be the tension of the spring which somewhat getting loose over time? But then why only on some places?
Did anyone experience this issue too?

Re: Finally pointed the UC18 at the green comet
Hello All,
? I picked up my 22" UC in October of 2019 and like most of us have
added a couple of tweaks. In my my case I have a 360 dew/light
shield made of Kydex. I need in my neighborhood. My location in the
eastern panhandle of West Virginia gives me Bortle 4.5 skies at best
(SQM 20.8-21.05). I also have a dark sky location 2 1/2 hrs away in
central WV (~ SQM 21.7). I've thoroughly enjoyed using this scope
after star hopping for over 30 years.? At this stage of my life I'd
rather spend more time looking at something than looking for
something(:>? Star hopping taught me the night sky however and I
treasure all the searches of the past. My current major observing
project is seeing all of the Herschel Objects (557 to go). I'm using
the baseline created by the Astronomical League Herschel Society
observing program. I enjoy reading what other are doing with their
UC's in this group.
Since Oct. 2019 I've logged 1,124 new observations so the scope is
definitely being used(:>
Clear Skies,
Matt Orsie - Hedgesville, WV

Hi Tom,

If you are, as I am, fan of very detailed images with tiny stars

have to say that adding a Starlight SIPS changed the way I enjoy
the views with my scope. This integrated televue paracorr in the

Tom,
when your telescope casts a shadow you are in Bortle 9. ?My sky quality meter never gets better than 18.5.
My favorite filter is the Optolong LeNhance for Ha and O3 which I use for nebula.
I also purchased a RGB clear set of filters.
the clear filter cuts my light pollution.
