My focuser is a PrimaLuceLab 2,7″ Hybrid-Drive.
My problem is that with CCD, barlow and Diagonal the focuser slides during focus operation, so I know there is a friction screw somewhere, but there are many screws, on Google I found a blueprint of the focuser and I found the correct screw, so I tight the screw a little bit and I resolved, below there is a photo of the focuser, hope it will help others!
This is my first analysis of the Periodic Error after I stripped down and cleaned up the mount some months ago.
Periodic Error recorded with EQMOD PE registration tool.
Just a reference, since I always forget the name of many Greek symbols…
Yes I decided to clean my mount finally after… 10 years!
It wasn’t that hard, I followed the guide of astrobaby (http://www.astro-baby.com/heq5-rebuild/heq5-m1.htm) and I recorded my work so to watch again to remember the process and doing it in reverse to put all together.
At the end now I have a much more smooth Right Ascension axis and hopefully I will have a better guide experience!
Soon I will do some test and measure the periodic error.
No more fear after the first time!
Finally I decided to buy this filter, Astronomik CLS-CCD, looking forward to see how it behaves in Seoul!
