Re: Remotely viewing with your dob

 

It might be wishful thinking / hoping for advanced features on the new product that ?is in development now to continue where the ServoCAT design left off. ? We wont find out the feature list until late this year / early next year.

Richard you mention a rumor about being able to do remote Argo two star alignment next year with next upgrade. Do you mean a firmware release for Argo that is coming? This is the first I’ve heard of that.
Thanks

Hi all,

When I purchased my UC18 i ordered it without the ServoCAT or powered ground board and enjoyed visual observing. The Argo Navis helped me find all those fun objects. ?Describing my views to my friends and family was not very satisfying.

Then I purchased a Mallincam DS287m camera. ?I pointed the telescope to the west of M42 and set the camera to take a 100 ms exposure once every 6 seconds as the very large/ very bright nebula drifted through my field of view. ?Then using free software ( MS ICE) i stitched 30 images to create a mosaic that blew me away!

No tracking required (for bright objects).

I so enjoyed sharing the experience i sent the mosaic to be printed on glass by one of those internet fab companies.

I came down with a serious case of UPGRADE FEVER.

Add ServoCAT and the powered ground board to my UC18.

Wow! ?I was now fully hooked on EAA but the upgrade fever got worse!

Gary's spiral search feature needed to be remote as well.? Gary sold me the CAT PAW!? It works at a distance that is more than Gary advertises.? Awesome.

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.

A 55 amp hour battery powers the telescope for about 11 hours before recharging. ?A single wire is placed between the deck boards “well under foot” to connect the battery/ voltage regulator to the powered ground board.

But the upgrade fever did not subside! ?I really like to filter. ?I bought a cool filter to pass OIII and Ha. ?Wow M1 really popped! ?I needed more filters! ?LRGB set of filters colorized my life! ?M27 is awesome!

A Filter Strip gets added. ?How cool, if only I had a remote way to change filters….I added a stepper motor and a threaded rod with a bit if Visual Basic software to slide the filter slide to the desired filter—works great! ?


But…changing filters means i need to refocus. ?If only I could remotely focus….I purchased a remotely controlled motorized focus. ?


wow, now I can slew, change filters and focus from my recliner with the rig sitting out on the deck!

The upgrade fever persists! ?What if i could place my telescope at a remote mountain top and I could live near my family?

Can i avoid having to be present to do a 2 star alignment for the Argo Navis? ?Rumors are flying over the speculation to be able to control the telescope prior to the 2 star alignment next year-with the next upgrade!

Please be careful / responsible with the upgrade fever!

I'm not a windows programmer. I had someone create the program for me way back in 2001 when I was developing the ServoCAT... and it has been worked on since by Pete Eschman. Although in his defense I wasn't aware of that bug and thus he wasn't looking for it. So the short answer is no. I might see if Pete has time to look at it.?

But to stress again - this only applies to the specific condition of Gen2 being upgraded to version 7. The reason why is there is an I/O pin that version 7 uses that was not used in previous versions. Since that pin was not used on a Gen2 it was grounded to keep it from introducing any issues, a common practice. What that means is that the (motor) encoder value is multiplied by 2 which is easily compensated for by entering a value of 1000 instead of the long used 2000 value. The bug appears to be associated with the change in that value and was never needed in the past or by Gen3.?

Hello sir.... write to me direct at rxdesign at ssvecnet dot com ... I'll send you a list of things to look for.

Slippery azimut movement (Obsession 18" with ServoCat and ArgoNavis)

 

Hello,
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 azimut movement (in goto mode) is on some places "slippery", I mean the drive wheel is slipping on a particular place on the edge of the ground board.

Close examination does not reveal something wrong at that place of the ground board

What could be the reason? Could it be the ground board is worn out on those places (I don't really 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?
Thanks for the feedback.

Anyone know where I can obtain it?? ?

Re: AN Reinitializing in Middle of Session

 

This problem has now been successfully resolved.? It was the rings on the PGB.? When Mike Zammit built my scope in 2020, he was sourcing the rings from a third party (not StellarCat).? He discovered quality control issues with those rings and now is using rings of his own design.? I was very fortunate to contact Mike when he had some open time in his schedule and he was kind enough to drive half a day to come up and fix my scope by replacing the rings on my scope.? Mike really goes the extra mile to support his customers.

Placing batteries in the AN worked as a fix while I was waiting for the rings to be replaced.

Thanks everyone for your assistance.? Very much appreciated!

If my telescope had a compas and a zenith limit switch…

 

All,

if my telescope had gps coordinates, knew where North and where the Zenth was could Argo Navis and ServoCAT do away with a 2 star alignment and support remote observing?
