Orion and Running Man Nebula
Orion and Running Man Nebula
Date: 01/17/2009
There are many better images of this target, but this one was made from inside Atlanta. AstroTech 80ED refractor, Meade LXD 75 mount, unmodded Canon DSLR, PHD guiding. 30 x 2 min subs through Lumicon Deep Sky and Orion UV/IR cut filter. darks and flats applied. Individual subs were green/blue but after stacking and increased color saturation, the red came out.
Eagle Nebula
Eagle Nebula from 2008 PSSG
Date: 09/30/2008
Eagle Nebula from 2008 PSSG. Unfiltered, 18 x five minute lights, master dark, no flats or bias. Curves applied. Unmodified Canon DSLR, AstroTech 80ED, Meade LXD 75 mount, manually guided.
Only time I've manually guided and I am grateful computer guiding is now available to amateur astronomers.
Globular Cluster
Messier 15
Date: 12/04/2009
Messier 15 - Taken from my back yard in Vinings, GA with a monochrome Meade DSI III and Orion Skyglow Imaging filter. I was doing some guiding and flexure tests and thought, "why not get some usable images"? A globular clusters is one of the few objects that can be imaged from urban areas without using narrowband filters. 49 frames, 60 seconds each, dark corrected and stacked. Taken through a CGEM 800 at f6.3.
Messier 22
M22. Just learning to use DSLR.
Date: 06/05/2008
Stack of five 30 sec. exposures with Canon DSLR. Starblast 4.5" f4 OTA.
Messier 16 - The Eagle Nebula
Pillars of Creation region in the Eagle Nebula
Date: 07/28/2009
Early test of the DSI III Monochrome from CEWMA. 20 subs x 2 min. each, luminance only, through CGEM 800 at f6.3 with darks applied. Incorrect camera settings produced extra noise, but the resolution in the Pillars of Creation was still more than I ever achieved with a color camera. I plan to image this target more with narrowband or RGB filters.
North American Nebula (NGC 7000)
North American Nebula (NGC 7000) in H-alpha from PSSG 2008
Date: 10/05/2008
Unmodified Canon DSLR with Astrotech 80ED doublet. Meade LXD 75 mount. Four x 15 min. subs, H-alpha filter with three 15 min. darks. No flats or bias. PHD guiding.
NGC 6960
Western Veil Nebula - a supernova remanent.
Date: 08/16/2009
Taken from the North shore of Lac Courte Orielles, Wisconsin. Stack of 12 - 5 min. sub-frames with darks subtracted. Taken with unmodded Canon DSLR through an AstroTech 80 ED mounted on a Celstron CGEM. Manually guided.
Bubble Nebula - NGC 7635
H alpha emission nebula in the constellation Cassiopeia
Date: 07/28/2009
My first tests with a DSI III monochrome imager. Taken at CEWMA, 11 subs x 5 minutes, luminance only, through C8 at f6.3. Darks applied. I used the wrong camera settings, creating more noise, but the overall result was still worth sharing. I plan to return to this target for more data through narrowband filter.
The Bubble Nebula
Emission Nebula in Cassiopeia
Date: 11/27/2011
The Bubble Nebula is a very dim object that is difficult to observe visually. This image was composed from two hours color data and two hours luminance data all taken at Deerlick Astronomy Village.
Messier 81 - Bode's Galaxy
Date: 10/19/2009
Messier 81 - Bode's Galaxy: Taken just before dawn after the PSSG. Only 7 subs of five minutes each. Canon DSLR through CGEM 800 at f6.3. PHD guiding.
Trifid Nebula
Emission and reflection nebula in Sagittarius
Date: 09/05/2010
Taken at Brasstown Bald and John Wood field using DSI III monochrome imager through AstroTech 80ED refractor.
M31
Andromeda (M31) from PSSG 2008
Date: 10/09/2008
Unmodified Canon DSLR, Astrotech 80ED doublet, Meade LXD 75 mount, PHD guiding. Unfiltered 12 - five mun. lights, four darks, no flats or bias. Levels and curves applied. Some more processing is needed to lower the black point and sharpen detail.
Rossette Nebula
Rosette Nebula
Date: 01/28/2009
Same data, different processing.
Taken after January meeting at CEWMA. Nine, 15 minute subs through Lumicon Deep Sky filter, stacked in DSS with dark frames but no flats. Taken with Canon DSLR through AstroTech 80ED on CGEM guided with PHD.
Messier 20 - The Trifid Nebula
Trifid Nebula
Date: 06/24/2009
A combination reflection and emission nebula near the constellation Sagittarius. Imaged from Stooges Field, this image is composed of 12 - 5 minute subframes without filters through a Celestron 8" SCT at f/10. Unmodded Canon DSLR, 4 darks, no flats or bias. CGEM mount guided with PHD.
The three lobes of this nebula usually appear with a stronger pink color. The prominant blue in this image may be the reuslt of the unmodded DSLR, which tends to be less sensitive to redlight.
