Hey Orion,
I've only owned the one C8, and I think it's great when it's in collimation and equilibrium, but that's been an ongoing battle. It doesn't have enhanced coatings, but I've been able to get more and more out of it.
Yeah, I'm pretty much limited to the city most of the time, so my options are limited. That's why I've gravitated more toward the lunar/planetary imaging, improving my humble skills with the help of this forum and through dogged persistence.
I appreciate your comparison and any other comments/suggestions you might have for using the scope.

One nice thing is you can use lower power eyepieces than with a C8 to get the same powers! I don't know if a focal reducer is available for it? I tried my F6.3 Celestron FF/FR WOW what a wierd visual sensation! kind of backwards coma.. One think I forgot to mention is the flatter field than a std SCT..

Hi Traveler,
I did make it from my balcony for sure, no joke! That with some chimneys smoking etc. However the seeing was great and I wasn't even there, I used Firecapture to capture and Autoguide at the same time for 3 hours, 60 avi's. The image was one of the best!
Here is an animation of those 3 hours: 3 hour animation 150mm Mak
I'm sure Richard won't have any problems to improve this!!
Edit: it's a bit dark I see, have to adjust my laptop screen when processing
Dang, what a great animation. I must have watched it about 4 times through! I'm just about to order a Orion 180mm, but I'm now in the 'due diligence' stage or what other stuff I'll need for it. EPs, diagonal, finder, etc..... Thanks for the movie!! Bob

You're gona love that scope Richard, brilliant piece of Maksutov!! Optics are said to be very smooth, mine ( 150mm ) is a nice sample as well, I won't sell never I think! Here a sample image with the 150mm, you are going to blast this away for sure!! Hope to see some images taken with your scope soon!
Wow! Thats so good! Sell your 150 mm and buy 180mm!

Illinois, how would you compare it to your C8?
Cant remember all details but I remember that C8 is pretty good on deep sky object. And I dont use it often and gave to astronomy club. Few years later, I bought Orion 180mm Mak-Cass because I like 2700mm for high power. 10mm eyepiece would be 270 power is good enogh to look at planets. I rather to use 10mm eyepiece than 3 mm eyepiece.
I have 3 telescopes and I am happy. IF I must have just ONE telescope then it would be C8 or C9.25....maybe C11!
