Anyone here have the fast Celestron COMETRON 114mmAZ Telescope?

Anyone here have the fast Celestron COMETRON 114mmAZ Telescope? Can you share me your experience with it? Did you need often collimation?

Good thing on Celestron website itself it said it parabolic mirror. BAD thing is a fast Newtonian of barely f/4 focal ratio.

I not worry about the coma because it parabolic mirror, but I worry about the frequent need to collimation due to it fast f/4.

Thank you in advance for your help.

One would expect collimation to be more critical than with a f6 Newtonian.  But does it go out of collimation? Is there even a collimation adjustment?  Are the cheap eyepieces good enough to give the best performance?  A f4 Newtonian would normally demand some rather expensive eyepieces.

If you wish to avoid coma, and opt for spherical-aberration rather...

I have the nat geo NY114CF which is also a fast reflector as well. Looks same as your Celestron 114AZ . I used it a couple days ago but I need to collimate it again. Which would be the second time .. (my mom moves my scopes around bumping them Willy nilly on accident)
