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)”

My first 30 minute sub exposure of the Horsehead Nebula.

Taken in HA and processed in pseudo color in Photoshop. This single exposure was taken with the QSI 583wsg camera on the Celestron C11 EdgeHD at f7. An updated photo that shows the impact of stacking a few additional narrowband images.

Supernova in NGC 4386

This is a recently discovered Supernova that I calculate is currently at magnitude 14.5. It is a crop of a 200 second exposure taken with a QSI 583wsg camera and the C11 Edge HD. Below is an inverted view.

A Messier Miss in Leo – NGC 2903

This is one of the better objects missed by Charles Messier in the preparation of his list of objects to avoid when searching for comets. Located in the constellation Leo it is around 31 million light years away and has the luminosity of 19 billion suns. It has been adorned with festive star spikes justContinue reading “A Messier Miss in Leo – NGC 2903”
