Re: Comet Tracking
Thank you for the info, and that sounds reasonable.
I am going to try download the comet database. and see if I can use Skyview.
I am bit worry that I am using old data, but

Re: Comet Tracking
When using the SKYX you also need to push the button Set Track Rates on the Telescope tab to get the correct tracking rate for a comet or an asteroid. I'd stick with the SkyView technique -

Hi Ralf,
Well, 15744 lines gives a resolution of 82.3 arc-sec. If your backlash is less than 82 arc-sec I don't know

Re: Update from 0.90R to 0.95A
H Ralf,
Well, I warned you that Parking and Unparking was changed, and needed to be reset. As for the meridian flip settings, in SiTech you can set them to any setting you want. However NOTE:

Hi Don,
updated now to .95A. Saved all my old files and made screenshots from the settings ;)
Can you please have a look on the meridianflip-thing...
MF on tracking is made from SGP

Comet Tracking
I have a question (I have to accept that I haven't search for it): how do you track a comet? I am thinking of the ATLAS comet.
I am using a MESU 200, and an Edge HD 9.25
Thanks,
Alvaro

Re: Keep On Top
Hi Ned,
I don't think that is a feature for SiTechexe. Do a search on the web for "AlwaysOnTop" and you will find a small program where you can set any window in Win10 to remain "On TOP".

Re: Update from 0.90R to 0.95A
Hi Ralf,
Oh My! 090R dates from 2013, seven years ago. There are so many changes since then, among the changes is a complete rewrite of how SiTech does parking and unpark. The later versions fixed

Keep On Top
Seems to me I remember an option to keep SiTechExe window on top of the desk top. I can't find it so maybe I remember wrong?

renishaw scope encoders to compensate backlash
Hello,
my do-it-yourself-mount suffers from a relativly great backlash on DEC. Even more, it changes. I guess the worm wheel is not 100% concentric to the axis. So normal backlash compensation doesnt

Update from 0.90R to 0.95A
Hello folks,
I am using Ver. 0.90R and everything working smooth, very satisfied! great compliment!
Never change a running system....
On the other side I want to stay up to date and update to 0.95A
