Here is my attempt to image NGC 2683 and some of the surrounding galaxies. Most of these distant galaxies are magnitude 18 or fainter. Located in the constellation Lynx, it is similar to our own galaxy as seen nearly edge on. NGC 2683 is thought to be between 16-24 mly away. A much closer and more
detailed shot of this galaxy can be found on the March cover of Sky & Telescope magazine.

This image of the region just south of Alnitak, the most eastern star in Orion's Belt, shows three different kinds of nebulae. The Horsehead Nebula (Barnard 33) in the center is a dark nebula. NGC 2023 is the blue reflection nebula just to the left of the Horsehead's base. The Flame Nebula (NGC 2024) at the left of the image is an emission nebula. This is an HaRGB image taken at a focal length of 620 mm.

Comet Lovejoy, C/2014 Q2, is currently (mid-January 2015) visible with the naked eye under dark skies. This image was obtained under the considerably less than dark skies of southern Springfield. Total exposure time was 9 minutes, consisting of 1 minute sub-exposures (3 each through R, G, and B filters). Images were acquired with a Celestron Rowe-Ackermann 11"/f2.2 Schmidt astrograph. Field of view is 100' x 75'.

NGC 1788 (aka The Foxface Nebula & LBN 916) is a reflection nebula located in Orion about 1,300 ly from Earth. It is the home of an active star forming region called Lynds 1616. Many hot young star inhabit the area.
This LRGB image is a composite of about eight hours of exposures.

M1 (Crab Nebula) is a supernova remnant located in the constellation Taurus. The progenitor star exploded in the year 1054 as recorded by Chinese & Arab astronomers. Since the SNR is only 6500 ly away, it has been well studied for centuries. The original star remains as a spinning neutron star (pulsar) only 30 km in diameter.
Narrow band filters reveal ionized sulfur (red), hydrogen (green), & oxygen (blue) mapped as per the Hubble palette. About 12 hours of 20 min exposures were combined to complete the image.

Here is an image of the brighter parts of IC63 (Right) & IC59 (Left). Both objects are part of the same gas cloud and are located in the constellation Cassiopeia, about 620ly from us. The nearby bright star Gamma Cas (not shown) is illuminating the nebulae. The picture is a composite of images taken through Ha, Luminous, Red, Green, & Blue filters.

NGC 660 is located in the constellation Pisces about 20 mly away. It's described as a polar ring galaxy because it has a ring of debris orbiting the galactic disk. A possible collision with a smaller galaxy is the likely explanation for it's appearance. Around 40, ten minute exposures through LRGB filters were combined to create this image.

NGC 925 is located about 30mly distant in the constellation Triangulum. It is classified as a barred galaxy with a bent bar in its core. Around ten hours of exposures were needed to capture the image through LRGB filters. Image acquisition in TheSkyX software, Stacked & Registered in CCDStack, finishing touches in Photoshop 6.

The famous Ring Nebula (M57). This planetary nebula is about 1ly wide and 2000ly distant. Twenty 50sec integrations were acquired and stacked with MiloSlick video software. Final processing in Photoshop.

Here is my attempt to extract galaxy IC 342 through the dusty disk of our home galaxy. It is located in the constellation Camelopardalis, about 10mly distant. Since the galaxy is obscured by dust it requires long 10min exposures to reveal any details. This image was created from about 13 hours of exposures through Luminous, Red, Green, & Blue filters.
