Thanks Much Chris! Was quite happy with how it turned out as it was my 1st light image with the Megrez 72mm. Great little scope..love it.

Thanks Hop. Was pretty impressed with how much the info the 72mm picked up myself. Would love to get another couple of hrs on it.

I really do not think I can agree with you Luc, but thanks alot!

Thanks Mark. The old Rebel still works pretty well. You might want to check the Astro Tec flattener as I here it does a better job. The one I have (W/O) still makes bad stars on the corners.

Hi Marc, really tried not to blow out the core as in the original. Masking in the shorter exposures sure helped.
