Re: Some regretable gripes (May 15, 2024)

I’ve never had a problem getting information from Lunt about repairs or when they were going to be shipping out an item when I called. Email usually took longer or I would have to send a follow up but it never got longer than a few days. Solar Spectrum was a different story. I think he’s a one man c...

That looks very good! Congrats on the unit. Which telecentric are you using? Powermate? Do you remember gain and exposure levels used? I used the Baader 4x telecentric at F/34. I was also using the ASI174 so sampling was not close to critical. The exposure was 10 milliseconds and gain was about 200...
