Re: January 29, 2015
Excellent! Did you image the resent triple transit of Jovian moons? Or know of any good shots? Stan

Re: Celestron 11" Edge reducer on 14" Edge?
Thanks Stan & Ed, That is my feeling too: it won't be ideal, but maybe not much worse than a normal, non-Edge 14" . Well, for getting some central stars in focus for a drift alignment, it doesn't

Re: Celestron 11" Edge reducer on 14" Edge?
If you look at the EdgeHD white paper, you will see that the position of the corrective optics in each of the four scope sizes is different. As a result, I would be surprised if the C11HD reducer

Re: Celestron 11" Edge reducer on 14" Edge?
"any idea if the 11" (Edge) reducer would work on the 14" (edge) as a temporary solution? " It is certainly worth a try. You might need to adjust the back distance a little. Reducer/correctors are not

Celestron 11" Edge reducer on 14" Edge?
Hi all, I've been very quiet so far since this group seems mostly focussed on planetary astrophotography instead of deep sky, but if anyone is interested, a few of my images with my 11" Edge are here:

Re: Jupiter December 27, 2014 GRS from DEC Large
"surprising how much oversampling you really need" The Nyquist criterion for sampling a Gaussian PSF is FWHM = 3.3 pixels. So "3.3 times oversampling" may actually be proper sampling for the best

Re: Jupiter December 27, 2014 GRS from DEC Large
That's really nice. It's surprising how much oversampling you really need. I usually go for an image scale that is about 3.3 times oversampling vs the diffraction limit of the scope (ie the Dawes or

Thanks. I was surprised imaging over 10 meter focal length paid some good dividends. Dan Llewellyn

I over sampled more than I usually do. It paid some unexpected dividends. C14, Zeiss 2.6x Barlow, Blackfly GiG E w/sony 104 cmos, one shot color. Dan Llewellyn Jupiter December 27, 2014 GRS from DEC

Re: Celestron c 14 orange
Hello Jose. If you are asking what the numbers mean on the back of the primary mirror in a C14 (or any other Celestron SCT), they are the "serial number" for the optics set. There should be a matching
