I have a 22"UC equipped with SC & AN, When I use the 22" I ordinarily go to "From Planetarium" mode immediately after the two star alignment,with a SkyFi III module connected to the S/C, I enter the

That is a great shot Richard, and under light polluted skies!! Could you even see this 8 x 6 arcmin +11.5 mag object in your eyepiece? I use Sky Safari 7 Pro on my i-Phone with Ski Fy and it controls

I built a 36" f/4.5 (f/5.17 with ParaCorr) alt-az scope, looks like a big Obsession, and it uses ServoCAT and Argo Navis in "From Planetarium" mode, plus The SkyX-Pro on a Win7 laptop bolted to the

Just curious how many folks are remotely slewing their Obsession with a planetarium program. I observe with my UC18 and Mallincam DS10cTEC and enjoy post processing images with PixInsight. Here is

Mike, I have installed a Primalucelab motorized focuser model Sesto Senso 2 on my UC18 to interface with the feathertouch focuser that Obsession mounted. PrimaLuceLab - Sesto Senso 2 Robotic Focusing

Hi Gordon, thanks very much, and I'll take a look at this. Cheers! Mike

Starlight Instruments makes the HSM20 moto-focus unit that’ll fit your FeatherTouch. You might get one direct from them or perhaps Woodland Hills or High Point Scientific might have one in stock…

Hi, I have a 20" f/4 classic Obsession with Starlight Feather Touch focuser (with curved base), built in 2020.? The focuser seems to have quite a low profile.? I was hoping to buy the Rigel Systems

I ended up going down another route. I bought this inexpensive tablet mount on Amazon: https://www.amazon.com/dp/B091GDKSK7 I clamped it to a strut via the slit included in the shroud. I tried it at a

Mark, I just made a “body” for each section and then just exported each section as a stand alone “stl” file and then sliced into gcode. Good luck. Richard ________________________________

Just information here guys. I have a 22" UC, and I have an 11" Celestron RASA, I have a Bahtinov mask that I purchased specifically for use on the 11" RASA,it has a hole in the middle of it similar in

Richard: Yeah, I know what a nice tool they are - I've got a 3rd party mask for my 8" Celestron Edge HD. I do not have a 3D Printer, but my son does. I used one of the online mask generators, but my

Mark (and others), Here is a link to an on-line tool with which one can create an .svg or .dxf file of a custom-sized Bahtinov mask: https://satakagi.github.io/tribahtinovWebApps/Bahtinov.html On that

Mark, Here is the view of the center toe of the crows feet to achieve good focus with my wooden version of the mask. [email protected] | Photo (

Mark, I created a Bahtinov mask in CAD with a hole to fit over the secondary and 3 notches to rest on the Obsession style secondary support. I have one more section to print to complete this version

Richard Where did you find the mask? I've got an 18" classic and would love to find a mask, as I want to do photography through it and am working with manual focus. Thanks! Mark

My 3D print version of a Bahtinov mask underway for my UC18. ?This will replace my wooden version that i cut out with my jig saw. Richard

In case you want to power your telrad from your scope power rather than internal batteries. ?I added a 12 volt dc to 3.3 volt dc converter and a DC power connector to power up my telrad. ?Never have

Thanks, I will. I’m thinking a shelf for the iPad and another shelf with holes to hold a couple eyepieces will be useful. Rod

Echoing Bill's comment. Mike Zammit fabricated a new dual-shelf stalk for my Teeters 14.5" f/5 which I recently completed a ServoCAT kit install on. Mike's work is both functional and beautiful and he
