Tadpoles – Happy New Year

These are the Tadpoles of IC-410.  They seem appropriate for the New Year when we are celebrating a fresh start or a new beginning.  This emission nebula lies about 12000 light years away, and the Tadpoles are about 10 light years long.  This is a stacked composite of 17 half hour h-alpha exposures taken through myContinue reading “Tadpoles – Happy New Year”

Orion Nebula Work in Progress

This time of year Orion is visible all night long. It rises in the Eastern sky at about 6:30pm, it reaches its highest point at an altitude of about 50 degrees in the Southern sky at around midnight, and it sets in the West at about 6:00 AM. Since it measures a little more thanContinue reading “Orion Nebula Work in Progress”

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”
