CNers have asked about a donation box for Cloudy Nights over the years, so here you go. Donation is not required by any means, so please enjoy your stay.
I’ve wanted to interferometrically test the two C14s that I have in my shop to get some good data on their optical quality for some time but gathering all of the equipment needed for such a test isn’t easy and I was hesitant to take my scope out of action when the skies were clear. Since it would probably be cloudy for months on end in winter, December seemed like a good time to try to get it done.
The owner of Stardust Gallery, Craig, was looking for volunteers to review an LED backlit lightbox containing either a Hubble image or an image of user choice. Since I had what I felt were fairly decent Milky Way images acquired from a session at a dark sky site late last Fall, I thought one of the somewhat processed images might be a good candidate to display inside one of the Stardust Gallery backlit lightboxes, and eagerly forwarded the image to the website.
The Rayox dovetail saddle (regular price $449 with adapter through Woodland Hills Telescope, with an initial discount for Cloud Nights members) is a breakthrough product that has significant advantages compared to existing systems, especially when working with heavy equipment. If this system had been available earlier, I could have avoided some potentially dangerous situations…
I have been using telescopes for film and limited CCD use for well over 20 years, and because of extensive business travel coupled with a spouse who cannot access the observatory due to disability, I needed a product that would be solid, reliable, allow for remote precise FOV rotation, temperature compensation, no requirement to find a zero-point and reinitialize the position of the drive motors, and easily adaptable to various optical tubes. As an engineer and former aircraft mechanic, I demand a great deal out of the build quality of anything that I own as well.
This review describes the Celestron Cometron 7x50s including my initial impressions along with examination during actual use for around 1 month. I live in a suburb in New England under Bortle 6-7 skies. I have 3 telescopes, the oldest of which I have had for one year.
This will not be a comprehensive, or even scientific review. I will just share what I would have wanted to know if considering purchasing one of these parallelograms.
What is a System of Binoviewing? An assembly of common observing equipment that’s powerful, portable, easy to use, effective, and fun to use. In my experience Binoviewers enhance the observation of Targets of Excess Light (moon, safe solar, and planets) I believe that given a half-decent telescope, most amateurs will see a much greater benefit from Binoviewing than upgrading any single optical component.

There once was a mystery in Lynx. The story opened in 1790 when William Herschel discovered a small, nebulous glow about 2½° northwest of 27 Lyncis. He later added it as number 830 in his list of "very faint nebulae" (abbreviated H-III-830) and apparently moved on without noticing a second, fainter blur of light just to the northeast. That second object was discovered 66 years later by William Parsons, 3rd Earl of Rosse, through his 72-inch "Leviathan" reflector. Both were later incorporated into John Dreyer's New General Catalog. NGC 2474 is described as "faint, pretty small, extended?, brighter middle, very small star?, large star north following." NGC 2475 is simply noted as "makes a double nebula with" NGC 2474.
