- beta firmware release
- guide stars
Huge improvement over previous guide scopes!
Received my scope from OPT last week and everything arrived as expected. I found the scope easy to setup and focusing was a breeze. My autoguiding average last night was less than .5 arc seconds total rms for a 2 hour session where previous guide scopes left me with .8 to 1.2 rms. Granted I was using the recent multistar guiding feature in asiair pro beta firmware release but acquisition of suitable guide stars was much easier with the added focal length and optical quality of this scope. Couldn't be happier! Highly recommended.
