Who hasn't already experienced the frustration of installing their camera, astro camera or accessory and it not working correctly? Suddenly focusing is difficult, different or the quality of astrophotos becomes poor.
 
Thanks to three explanatory videos and pdf support, we approach the theme of accessories by presenting them in section 1, then explaining their assembly, paying particular attention to backfocus. We also offer you a link to find out the backfocus of several dozen digital cameras and cameras (including probably yours).
 
There are a multitude of accessories that allow you to improve and automate all kinds of processes. Autofocus is a perfect example of a major improvement in the quality of its astrophotography. Indeed, due to the changing temperature during the night, the focus is affected and requires regular corrections. Rather than taking out your Bahtinov mask and having to change targets to point at a bright star, autofocusers allow you to configure them so that they themselves detect changes in atmospheric conditions and automatically and regularly perform focus checks. .
 
So simplify your life and discover our lesson dedicated to accessories so that you don't waste time searching for information on a dozen websites and forums.
