Can we just use HFR on refocus at each filter for set times, I have literally placed mine on the telescope after years of it sitting on the shelf...Hope is suffices for this Orion AG10...sorry to kind of hijack the post as well Mark  Shame to hear about these dramas, can really be frustrating when things don't line up. |
Hi Daniel,
The issue with the internal sensor is that when the focuser moves it generates heat which in turn interferes with internal temperature readings. It is also good to get the temperature from near the lens/mirror which the external sensor allows. Of course, this has no real effect if you do your refocussing at set time intervals or image count, only if you do it based on temp changes.
Good luck getting everything up & running, an EAF makes things so much easier & helps hold the focuser in position. Hope your dry season is dry, my summer has been pretty much nothing but nightly clouds & rain.
Cheers,
Mark
