This is my first Mars of this apparition. Under average conditions: http://www.bcastropics.com/img/gallery/3/Mars_200114_084943_g2_ap13-RGB3-set_full.jpg

I imaged Jupiter recently (not good seeing) and was reminded how quickly it rotates; even the moons go whizzing by. I think you are right to use a Bayer camera for color images of that planet. Stan

Hey Stan, "The primary aberration is not the usual chromatic where colors focus at different points but rather convoluted spherical aberrations" You are correct. Thisis why I image at 8 inches from

That can be a difficult decision, especially if you find a used C14 to save some serious $ compared to an Edge. Classical C14's have had an excellent reputation for several decades and there are very

" SCTs corrector plate can contribute to CA because technically it is a lens, the prescription is weak and is zero" The primary aberration is not the usual chromatic where colors focus at different

Hey Stan, Although SCTs corrector plate can contribute to CA because technically it is a lens, the prescription is weak and is zero in a good chunk of the glass. "So a Bayer ("color") camera will

Thanks Brian. I have used mono and color side by side for 4 years now and from my location and with my equipment see no difference. Of course, your milrdge may vary... Dan L

These days it is mostly "hit" on both the C14HD and the standard C14. If you only care about looking at or imaging the center of the field, then the standard C14 will be fine. But if you want a nice

Hi John, I have had mine for about 2 1/2 years and have not had any problems with it. Optics remain consistently good. To improve focusing and mirror flop, I have an external focuser (FLI Atlas) and

I've had a C14HD for about 1 1/2 years. It is observatory mounted and used for visual and Mallincam use. The optics are simply superb. I do not have experience with any older Celestrons, but it is

Hi group, For those of you that own the new C-14 EDGE HD scopes, do they consistently have high quality optics, or is it HIT or MISS? Do you feel that they are WORTH the extra $$$ photographically

Seeing was good only briefly but I captured one decent shot: http://www.bcastropics.com/img/gallery/3/2014-01-13-0424_3-Jup_L_13_08_2012_101226-RGB3-set_full.jpg

"good seeing for my red channel data, only to be stymied with much poorer seeing for the green and blue" That may be what is actually happening because longer wavelengths are less affected by seeing.

Well done Dan! You get more out of an all color camera than anybody I know! I actually bought a color flea because I admit to getting tired of getting good seeing for my red channel data, only to be

Conditions pretty soft, not turbulent. Got more detail than expected. In photos section: <http://groups.yahoo.com/neo/groups/C14_EdgeHD/photos/albums/1517094101/lightbox/1757006156> Dan L

I finally had some decent conditions 3 days past opposition. This is a combination of 3 sets of data taken over 11 minutes:

Ed - You may be right, I claim no expertise here. I just didn't like the idea of focusing with a loose mirror then tightening the mirror down, then slewing to another sky location and doing it all

Dean would generally be wrong. If you happen to have a C14 with extremely small focus shift you may be OK, but in general the C14 has the most focus shift of all the Celestron SCTs. For imaging, a

Thanks Mark :-) Could you send a link to the resulting mosac ? Christian Le 03/01/2014 13:08, crossley_mark a crit :

I have a ZWO ASI1200MM camera. It is a very fine camera, esp for the price. max QE = 70% and read noise is only about 3e- at maximum video gain. It is very good for lunar planetary but also performs
