The Orion Nebula - M42

Submitted by jimwcoleman

I haven't been out in awhile due to the large number of hours I have to give to my employer, but I did get out under the Port Orchard, Washington skies at 2 a.m. this morning. The Meade 115 Series 6000 APO Triplet has barely been used since I purchased it some months ago, so I decided to give it some light. I also used my ASI 1600MM Pro camera. 

Widefield view of Sadr

Submitted by jimwcoleman

Here are some wide-field views of my favorite star, Sadr. Located in the constellation of Cygnus, Sadr is high overhead in the late evening this time of year. Deep in the heart of the Milky Way, Sadr is surrounded to all sides by nebulosity. Significant nebulae like the North American and Pelican Nebula are in the region. Photos were taken with an AstroTech AT72ED refractor, using a Canon 60D at prime focus, 13x2 min subs, ISO 1600.

Caldwell 33: The Veil Nebula

Submitted by jimwcoleman

Captured from Port Orchard, Washington on a beautiful August evening.

Scope: AstroTech AT72ED Camera: Canon 60D (prime focus), ISO 1600, 12x120 sec subs, 5 darks Mount: Celestron AVX Stacking software: Maxim DL

I forgot to use my coma corrector. Once I realized that, I stopped the capturing sequence, realizing that the photos would not be what I had envisioned. But the stacked image isn't that bad. Additional subs would have brought the nebula out more.... 

Messier 27 - The Dumbbell Nebula

Submitted by jimwcoleman

Always a favorite target, the Dumbbell Nebula (M27) is climbing high into the northeastern sky after dark. The Dumbbell Nebula is a planetary nebula in the constellation Vulpecula, at a distance of about 1,360 light-years. This object was the first planetary nebula to be discovered; by Charles Messier in 1764. The nebula is 1,360 light years from Earth.

Image was acquired with an 8" Meade LX200 with a Canon 60D at prime focus (ISO 1600, 13x60sec subs). Stacked with Maxim DSLR.

NGC 6888 - The Crescent Nebula

Submitted by jimwcoleman

A photo of the Crescent Nebula taken from my back yard in Port Orchard, Washington. This is not that great a shot, but best I could do in the conditions, with high hazy cloud cover (thickening, intermittently, making guiding problematic) and bad batteries in the camera shutter control. But I did what I could.

NGC 6992 - The Veil Nebula

Submitted by jimwcoleman

After inadvertently seriously disabling my Meade 8" LX200R last night out (necessitating these repairs), I set out tonight to prove that my repair work is solid.

Having been disassembled, the scope was completely out of collimation and out of alignment. After some star collimation and alignment work, I slewed to the Veil Nebula and started shooting.

This was the final result, and is good enough to certify the repair. It's great to be back in business!

IC1396 "The Elephant’s Trunk"

Submitted by thenakedastronomer

The Elephant’s Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant’s Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. Orion 8 Astrograph Newtonian, Baader MPCC coma corrector, Canon T3i (modified) at prime focus, f3.9, ISO 1600, 17×23 subs, 2 darks.

The Great Orion Nebula

Submitted by thenakedastronomer

This is Messier 42 (The Great Orion Nebula), a very easy target in the constellation Orion. This time of year, Orion rises over the eastern horizon and is well into the sky by 8 p.m. (Canon T3i at prime focus on an Orion 8″ Astrograph Newtonian, Baader MPCC coma corrector, 10×15 sec subs, ISO 1600, DeepSkyStacker).

NGC 7023: The Iris Nebula

Submitted by thenakedastronomer

The Iris Nebula, also NGC 7023 and Caldwell 4, is a bright reflection nebula and Caldwell object in the constellation Cepheus. NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158.[1] It shines at magnitude +6.8. It is located near the Mira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.
