The Rosette Nebula (Caldwell 49)
The Rosette Nebula (also known as Caldwell 49)
is a large spherical H II region (circular in appearance)
located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The cluster and nebula lie at a distance of some 5,000 light-years from Earth.
The image was taken in my backyard in Regina Saskatchewan, Canada. I live in the suburbs and my skyglow is around Bortle 8.
The photo was taken with a 71mm William Optics Zenithstar refractor and a ZWO ASI1600 monochrome camera, mounted on the Skywatcher AZ-EQ6.
I shot through a Optolong narrowband filter set, (7nm Ha, 6.5nm Sii and 6.5nm Oiii).
- Hydrogen-Alpha : 300s x 47 (47 images, each being 300 seconds in exposure)
- Sulfur-II : 300s x 27
- Oxygen III : 200s x 79
Total exposure is approx 10 hrs.
I assigned the Ha channel to Green, Sii channel to Red, and Oiii channel to blue and combine them to process in the Hubble Palette.

"A New Hope"
This image is from a visit to Death Valley. By the time
I flew into Vegas, got supplies, and drove out to Death Valley, the only campsite I could snag
was near the Mesquite Flat Dunes in a sea of RVs. I managed to sneak in a quick scouting trip
out to the dunes before the sun set to mark on GPS a couple of good dunes for this image.
After attempting to sleep in 90F temps, my alarm had me up at 1am and off to the dunes I
went to make this image and several others. This particular image is a composite of two
images. The silhouette of me standing on the dune is one image, and the sky is another, shot
on a tracking mount at around a 70mm focal length. The longer focal length is essential to
compress the Milky Way to get it to appear larger in the frame. I opted for the wide aspect
shot to increase the feeling of isolation, which turns out to be reasonably appropriate for
the times we are in!
