Hi everyone

For our monthly visit to targets suitable for clear skies around full moon, last night we decided upon the double cluster. Also a chance to test the latest GSO Newtonian. It looks like they've upped their game recently. A visitor (A real live visitor. Not seen in these parts since March!) wanted to see if it was possible to guide it, a 203/1000, with a separate guide telescope. It wasn't. Until...

... we remembered @laser_jock99's mirror cell modifications.

Next, the dovetail supplied with most big reflectors is totally inadequate, with the obligation to use an OAG. One proper dovetail plate and top rail later and we guided easily for 5 minute frames using a 60mm guide telescope. Unfortunately, with the moon and big aperture, we were limited to 3 minutes, albeit with alarmingly centralised histograms. We managed 27.

Would love to hear from other gso owners. This ota at least seems rather nice.

Thanks for looking.
