celestron 9x50 focusing problem with qhy5

[paler31]

Hi I wonder if anyone can help? I thought I would have a go at autoguided astrophotography and read about hhow some people had good success with using finder scopes as guide scopes and I thought i would give it a try. I have a celestron 9x50 finder scope and I purchased a qhy5 guide camera with an adapter from modern astronomy. The camera seems to work ok the only problem is the finder cant seem to focus enough to produce a good enough image for guiding. Has anyone got any ideas how I could over come this problem. Any help would be greatly appreciated.

I use a BigEye finder with a DSI to guide, and I too found that getting the camera to focus is tricky. In the end I found that sticking my 2x barlow into the finder, and then the camera into the barlow did the trick Not ideal as you reduce the FOV and light gathering potential, but focus is now possible for me.

What I really want is a 1x "barlow" Not sure that they exist tho...

Thanks for the advice I shall give it a try but I am not sure how to connect my barlo to the finderscope as I have to remove the eye piece holder of the finder to attach the adapter that screws into the qhy5 directly.

Regards
