M33 – Triangulum Galaxy
It is a little easier to image galaxies since you can use simple RGB filters. This was done with a Luminance filter and I plan to add the red, green and blue later. M33 is a part of the local group of Galaxies which includes Andromeda. It is “only” about 3 million light years from earth. Continue reading “M33 – Triangulum Galaxy”
Elephant Trunks Nebula – IC 1396 – Color
My earlier greyscale photo of this nebula was derived from 15 one hour exposures through an H-Alpha filter which were used as the red channel in this color image.. An additional 11 half hour images were taken through an OIII filter for the blue channel. An RGB color image usually uses three different monochrome images.Continue reading “Elephant Trunks Nebula – IC 1396 – Color”
Rosette without stars…
Rosette with wider band filter
By adding data from a wider band 5nm HA filter the image is softer and some more detail is observed in a few spots.
Rosette Nebula – Cropped
This is an interesting part of the Rosette Nebula.

Rosette Nebula – Caldwell 49
This is a stacked image of 6 half hour and 7 full hour h-alpha exposures.
Horsehead Nebula (IC 434)
It is a now a good time to image and visually observe the Orion Nebula since it can now be found in the Eastern sky. For those with binoculars, Orion is an easy target. The Horsehead Nebula is located just to the south of the star Alnitak, which is the star that is farthest east onContinue reading “Horsehead Nebula (IC 434)”
