[Aavso-photometry] Optistar

[pcyoung]

Am trying out this ds 335 ice camera
No comment yet anyone there had experience with it?
   I have heard " it's too good to be true" one group - cloudynights.com
I'm hoping its an exception
So far .... Got some good dark frames
   optistar customer service is very good
    Still waiting for my hx516 adaptor
   course I'm a klutz when it comes to hands on
  cya
