Hi Mike,
No, not using the MPCC yet, I only have the T-ring screwed on to the 2" flange thread after removing the 1.25" focuser barrel. I am not sure the best way of connecting the T Ring to the MPCC as I couldnt see how to do that with what I have, perhaps the spacer you mentioned is what I need.
Not sure if the coma is from the F5 or due to the stars wobbling a bit on the drive. I noticed in each run of 10 images, I had to chuck away about 3 due to blurred stars. Strange that it was so periodic, some were GREAT, by flicking through each saved image in a viewer, I could tell which ones weren't going to cut it.
I think the focus was pretty good, I didnt change it the entire time I collected M8, M20 and M22.
I tried a quick look at NGC253 in Sculptor when it rose but with 30 sec subs, it was lost in the Sydney Skyglow from the East, need to wait until its at the Meridian.
Not bad for a newbie hey?
Cheers
Chris
