Off Axis Guider (Atik) Question(s)
Posted 06 December 2011 - 02:15 PM
After months of threatening to do it, I believe I'm going to dabble in some prime focus imaging and I'm looking at ordering up one of the Atik off-axis guiders to assist in the guiding chores. The image train I'm looking at right now is this:
C11 Edge HD --> T-Adapter --> Off Axis Guider --> QHY8PRO camera
I'm considering downsizing to a more manageable focal length as well and my image train could quickly look like this:
AT8RC --> Field Flattener --> Off Axis Guider --> QHY8PRO camera
Either way, if I understand correctly - I have a small problem to overcome. The off axis guider has female M-54 threading on both sides....so I'll need:
an M-42 female to M-54 male adapter to fit between (and connect) the flattener & OAG
and a M-54 male to M42 male adapter to fit between (and connect) the OAG to my QHY8PRO.
So now my questions:
1 - Am I correct in my understanding of what I need above?
2 - Anyone have a source for these adapters? There's a bewildering assortment out there and a definite lack of knowledge on my part has me shy to take the plunge.
I've spent a good amount of time looking at some of the results that are out there. BuckeyeStargazer has done some really cool stuff with a setup almost exactly what I'm considering. Anyway, thanks for any help or advice you can offer.
I'm not even married to the Atik OAG...but it's been reviewed favorably, seems reasonably priced and the t-thread for the guide camera will fit my current guider (QHY5).

Did you have enough of Hyperstar?
Not quite yet. I'm beginning a transition out of such wide field imaging though. Hyperstar is tough to beat for wide field imaging in a very short amount of time. My motivation though has always been to get to some longer focal lengths and shoot "eyepiece sized objects" and I feel like I'm approaching the point where I'm ready to start moving in that direction.

I really like the Atik OAG - I got it a few months ago and have been very pleased.
