It will be interesting. The larger diameter will certainly give better results in the case of photography, allowing you to pick out finer details. But what about visual observations? A lot of additional factors are important here - contrast, color, etc..
I haven't forgotten your question. I just have not had the MN65Q out until last night. It needs some collimation attention. It might be awhile, because I do not want to rush adjusting anything, given what, to me, is a very complex process.
My first peek at the moon showed lots of detail, and at Jupiter, there were distinct bands, but everything was very slightly "off" from what I expected. Last night confirmed my concern that collimation was not perfect. However, the first time I used it for a few minutes, the seeing was FAR better than last night. Regardless, I need to take it slow and do a little research and tweaking.
