Hi all, This time, i would like to share this image of the Rosette nebula. This one was acquired in last december with my FSQ106Ed refractor and the STL11k...
Thanks, Danny. Your configuration is very similar to my current one: FSQ (N) as the imaging scope and a Borg 45ED riding piggyback. I'm curious about the plate...
Hi Larry, Sorry I am a litle late. You want to put the sensor closest to the element that is changing with temperature. In most refractors, the focus changes...
Hi Eric, The FSQ has SocalAstro dovetail plates bolted directly to the FSQ's rings. The SV80S, on top, then uses Losmandy DAs to attach to the top dovetail...
