Primaluce Esatto focuser

[Howardk]

I have heard that previously there was an issue with getting a Esatto focuser to work with sharpcap’s focus assistant

Does anyone know if the problem was resolved?
I am looking to buy a 2” Esatto but only if it works with the focus assistant tool which i love

Hi there,

i have an esatto 3" on one of my RC10 and I never got any issue with it. By the way this is the focuser that works the best and it always acheive focus fast and accurate.

kind regards

Hi,

not sure what the problem might be - I found this post on Astrobin (https://app.astrobin.com/forum/topic/20 ... cus-issues), but that seems to be a misunderstanding of how the ASCOM focuser system works...

SharpCap doesn't care about the 'StepSize' of the focuser in microns (in fact it doesn't even bother asking the ASCOM driver for that information, and some ASCOM driver's don't provide it anyway). ASCOM focusers are moved in 'steps' (of whatever size they are), and 1 step is the smallest possible movement.

Other than that, since there is an ASCOM driver for the focuser, it should just work. Sometimes there is an odd incompatibility between SharpCap and particular ASCOM drivers, in which case using the ASCOM 'Just A Hub' trick to force the ASCOM driver to be hosted in a separate application outside of SharpCap almost always resolves the issue.

cheers,

Robin

Thanks Robin

Will try it all out next week

works fine with my 4" esatto as well, the only issue I had long ago was that you could not put a large enough step count in for the move between focus positions, but Robin fixed that a long time ago.
