Recently got a Celestron RASA 8 after falling out of the hobby for 5 years or so and picking it back up recently as the pandemic means I'm home every night with no work travel. 

 

Wow have things changed in 5 years! At f/2 RASA scopes are so insanely fast that I can do in an hour what would take all night is the past. The ASIAIR Pro made quality polar alignment super easy to do. So much so that even unguided I get nice sharp stars over a few minutes of exposure. Add to that modern bandpass filters that makes its possible to image from the backyard instead of traveling to a distant dark site. I'm hooked (again)!

 

 

Equipment:

RASA 8 Astrograph

Celestron AVX mount

ASI071 camera

ASIAIR pro

ZWO Duo filter

Congrats on your image and welcome back! Yes, there are a few of us Rasa fans here... sure is nice to get images in a few hours as opposed to dozens of hours.

Hi

 

I have the same setup RASA 8 on AVX mount, Celestron LPR filter for RASA, 294MC pro.  Did you experience walking noise issue with our unguided photos? If so, how did you fix it.

 

I am having the walking noise on my photo taking with RASA, Celestron told me I have to dither!  That means I have to use a guide camera, I am trying not to use auto guide that's why I upgraded to RASA.
