SharpCap Forums

Many congratulations! It is kind of you to put in so much work for our benefit.

Dear Robin, After discussions with Damian Peach, it seems that to get the best results, you must recollimate every time you adjust the Atmospheric Dispersion Corrector to adjust for altitude changes unless the target is high in the the sky in which case you don't need the ADC. Not for the faint hear...

Dear Robin,

Thank you. This sounds like a good plan.
I am talking to my dealer about this.

<t>Dear Robin,<br/> <br/> Wow! That's brilliant. I had no idea that this was possible, thank you.<br/> Looking at other posts on the forum, I see that you have said that<br/> one can turn it on (after calibration) in Sharpcap. I also see<br/> that my ZWO EAF does not do this.<br/> <br/> Please are y...

Dear Robin, Thank you. Your approach sounds good. I think my first experiment may be to try to replicate the findings of this chap who reckons that the focus varies linearly with temperature. https://www.youtube.com/watch?v=Jyk8i64Gl9A Then the obvious thing to do is to set up a small computer that ...

Dear Robin, Thank you for explaining about re-focusing on stars being better and for suggesting an outline procedure. What do you see as the main challenges for unattended imaging? I have bought one of these but have yet to be able to evaluate it properly. https://www.firstlightoptics.com/other-acce...

If I want the script to refocus every half hour,
is it possible for the script to refocus on the planet,
or should it refocus on a star(s)?

Thank you. I shall give it a try with my own 10micron mount in the observatory when we get some clear nights. The reason I was asking about other makes is that I am thinking about a telescope to travel with to an island with better seeing than here in Cambridge. I would like something more portable ...

Dear Robin,

Thank you for taking the trouble to explain all this. Much appreciated!

Do you think feature tracking is likely to work with a 10micron mount?
It does not seem to be listed here:
https://eq-mod.sourceforge.net/reqindex.html

Please would you recommend make(s) of mount that talk to Sharpcap nicely for planetary imaging?
I would like the mount to be guided by Sharpcap's feature tracking.
My tube is a Celestron 8".
