ngc3372 w/QHY8 long exposures NO DF rem
Hi All,
Putting the QHY8 through its paces, tried some long exposures to see what the thermal noise comes up as, unfortunately I had a bit of cloud drift past which brightened the background a bit, still they look quiet (no thermal noise) published figures are one thing, in practice things often turn out differently, looks goo so far, now ill mount it on the LX200-10" at F10 and we shall see.
Pix. 12 Min. & 20 Min. Exp. No DF removed, guided, Scope ED80
