The Horsehead Nebula in HaRGB A famous, indeed iconic nebula in the constellation Orion, The Horsehead was not even discovered until 1888 with the advent of astro photography. It is very faint to see visually with a telescope. The image above was captured with my TEC 140 refractor and Atik 460 CCD camera with Astrodon RGB and Ha(3nm) filters. It contains a total of 120 minutes of Ha data and 45 minutes each of RGB data, everything binned 1×1 with 5 minutes exposures.

Hydrogen Alpha North American and Pelican Nebulae Above is 120 minutes worth of Hydrogen Alpha data captured in five minute exposures with an Astrodon Ha 3nm filter and a Samyang 135mm camera lens on a Moravian Instruments G2-8300 CCD camera. RGB data I then captured one hour in each of the Astrodon R,G and B filters with the same rig as detailed for the Ha image, again in five minute exposures. However, use of the superb Astrodon E series RGB filters produce a nice image and the colours are brought out quite nicely although it lacks a bit of punch and vibrancy. The bright star to the right is Deneb. HaRGB image In Photoshop I broke out the red channel and then blended it as a 50:50 mix with the Ha image (at the top of this page) before recombining back into RGB. I also saved a copy of this…
The Draco Trio The Draco Trio is a group of three galaxies in the constellation of Draco, The Dragon. They are located about 120-130 million light years away. This image was captured over the winter 2019-2020. I used my TEC140 refractor with Atik 460 CCD and Astrodon LRGB filters. The luminance is four hours of 15 minute exposures binned 1×1 and the RGB one hour in each filter binned 2×2. Mount is MESU200 guided with OAG with a QHY5. Draco Trio Annotated Draco Trio Inverted
