Wizard Nebula (NGC7380)

Buy a Print (New version captured July, 2013 – posted here September 2013) One of my first targets with the AP 142 telescope, the Wizard is interesting in that it contains a fair amount of both oxygen and sulfur in addition to the predominant hydrogen. With more OIII and SII data I suspect there would be quite a variety of colors in this image, but it still took special processing to bring out the OIII and SII details and color. The Wizard (NGC 7380) is in Cepheus and about 7,000 light years from Earth.  Look for his hat, nose, and […]


Bubble Nebula (NGC7635)

Buy a Print The Bubble Nebula is a hydrogen-rich emission nebula in the constellation Cassiopeia. It is 11,000 light years from Earth. This photo also includes the open cluster M52 and NGC7538. This image is a composite of shots from two sessions.  The area immediately around the bubble is from my AP 142 at f/7.5 (1065mm focal length), while the rest of it was done with the AT111EDT at f/5.6 (622mm fl). The wide shot was the first image I captured with my Astro-Physics Mach1GTO mount. Captured on 2011-10-25 & 26 at Wa-chur-ed Observatory using H-alpha for red plus green […]


Lamb’s Head Nebula (NGC7822)

Buy a Print Although this region is part of a larger structure known as the “Question Mark Nebula” (this being part of the semi-circle in the question mark), this fascinating region itself does not have a common name. I’ve decided to call it the “Lamb’s Head Nebula” because of the obvious (to me, anyway) shape near the top center. Scope: AT111EDT at f/5.6 Mount: AP Mach1 Camera: QSI 583 at –15C


Pacman Nebula (NGC281)

Buy a Print (Updated Dec. 2017) As is often the case, the name of this nebula is more sensible when seen with the eye through a telescope than in a photograph that includes colors we can’t see when this faint. But if you imagine the shape of the famous video game character I think you might see how this object got its name. The previous version of this target used only H-a and O-3 data.  Adding S-2 (and quite a bit more exposure time) really added a lot of detail and color. Scope: AT111EDT at f/5.7 Mount: AP Mach1 Camera: […]


Hotech SCA (Self-Centering Adapter)

Almost every customer for our MRT adapter has asked, “This is great, but how do I attach it to my telescope?”  The answer has always been that a direct threaded connection is best, but since most telescopes don’t have T-threads, the next best solution (and one that is far more universal) is the SCA made by Hotech.  So to make it even easier for you, we have arranged to be able to offer you this brilliant product. The SCA is like a standard 2” nosepiece-to-T-thread adapter, except that instead of using one or two thumbscrews to secure the adapter (leaving […]


MRT (Mister T) T Mount Adapter

Astro-photography with a DSLR camera is a great way to go for high quality images with minimal expense and headache, but the traditional T mount adapter was never intended for this application and leaves much to be desired.  MRT solves the problem. First, MRT has 3 set screws that tighten against the lens flange of your camera to dramatically improve the rigidity of the connection between camera and telescope.  The set screws have nylon tips, so they won’t mar the finish on your camera. As if that wasn’t enough, MRT also provides a much better camera rotation capability.  Standard T […]
