This month's subject: M13 with NGC6207 in the frame
Post your entries here.

The rules:

1. All entries must be captured within the same season as the contest. For example, if the subject was Orion Nebula, than any photo captured during this particular winter (or period that it was visible) would qualify for the contest. Entries must be made prior midnight of the last day of the month.

2. Images to be considered for entry to the Challenge must be posted to and visible in the challenge submissions thread. A link to an off-site image without a version that is actually displayed in the Challenge submissions thread will not suffice and is subject to disqualification.

3. Images to be considered for entry to the Challenge must conform in all respects with the site wide image posting requirements. Entrants may elect to set this "entry image" up as a "clickable link" to a higher resolution image if they so desire, and entrants may also elect to instead provide a separate link to such an image if they so choose. If the entrant provides a legally sized and working "clickable link" as their "entry image", that "clickable link" will be included in the polling thread so that voters can examine the high resolution image before voting. However, any "entry images" displayed on the CN site that do not meet the file size and pixel dimension requirements will subject the entry to disqualification. Any questions on this rule? Just ask.

4. Please include the equipment used to take the image. Scope/Mount/Camera/Focal reducers/Barlows...whatever. Also include your location.

5. Please do not post comments in the entries thread. It is just for these wonderful images you all will be submitting.

6. The equipment must be yours. Doesn't matter what it is. 20" RC, ETX70, 2" Tasco or an 8" TMB.

7. No collaborations. You must be the operator. You must setup, align, take the exposures and process them yourself. You can have help mounting that 26" RC if need be. No remote scope images. Unless you own that remote scope and have set it up aligned it and hooked your camera up. Then you can use it. No pay by the hour renta-scope images will be allowed.
*If you have a physical disability which prevents you from being able to set up your equipment, you may still post images in the contests. However, you must own the equipment.

8. Most importantly! Have fun. Support one another's efforts. As we all can learn from this and enjoy each others accomplishments.

Happy April everyone! spring should eventually come! I sit on my deck and close my eyes so I don't see the snow and listen, I hear spring birds! Bring on the Spring!

Here is my submission for this month:

Object: M13 Keystone Cluster
Location: Enfield, NS Canada
Date: April 6 into the 7th, 2013
Camera: Canon XSi / 450D Gary Honis Full Spectrum modified
Coma Corrector: Baader MPCC
Telescope: Orion 8" F4 Astrograph
Mount: Celestron CGEM
Guiding: Celestron 80mm Guidescope with a Celestron Nexguider.
Subs: 120s x 58 Integration time of 1hr52m
Darks/Bias/Flats added
Processing: Pixinsight 1.8 RC5
Post-Processing: Pixinsight 1.8 RC5

Hanging out in space at a distance of 25,100 light years, this 24 million year old beauty is one of the most impressive globular clusters for the northern hemisphere. Containing over a million stars packed into a 145 light year sphere, the center of this glorious object is 500X more concentrated than its outer perimeters. And out of all of those stars there stands one stranger… Barnard Number 29. What is it? In a world where all the stars should be the same age, there is a spectral type B2 – a young, blue star. Where did it come from? Apparently on one of M13′s journeys around our galaxy, it collected a field star, for radial velocity measurements have proved that it does belong to the globular cluster!

Also, here is a link to the FULL resolution of the image, take note of the detail in NGC6207, there is also another galaxy to the north of NGC6207. This file is 4MB. I can count 17 galaxies in the background.

My submission and first DSO image

Equipment:
Orion SkyView 6" Deluxe newtonian modified for prime focus
CGEM mount unguided
Sony A57 DSLR unmodified

The exposure is a single frame, ISO 1600, 107 sec.
Processed with StarTools

I took this image while trying to figure out how to autoguide with the CGEM and an SSAG/ Orion ST80 combo. That effort was unsuccessful but I did manage to get this one frame with round stars before the sun came up.

A few nights later I finally figured out the basics of autoguiding but alas I did not use the camera during that session. I wanted to keep the session simple and keep my head in the autoguiding game and not be distracted with imaging. Things should get easier from here on. I think I am over the first big learning hump.
