I
just finally got a decent DSO image, so count me in the ¡°if I can do it,
anyone can do it¡± category..

Tonight
was below the normal.. 3 hours and I was at 0.92 arcseconds total RMS on both
axis.. Normal
is ~0.75, but my seeing was bad.. Polar Alignment is off by 5 arcmins..

Typical Guided Performance of GM8G, GM811G, and G11
?
Thanks
all, I really appreciate the thoughtful responses. It sounds like the GM8G with
a guide scope should be a pretty decent setup to start with. Since my focus is
on live stacking at outreach events, I will probably mostly use it for the
larger and brighter objects. I currently have a 750mm FL 6-inch Newtonian on a
stock mount and a 200mm FL DSLR lens for wide field. Eventually I may look into
getting an APO refractor somewhere in between
those focal lengths.
