Welcome to the Cloudy Nights Monthly Challenge Imaging Competition in CCD Imaging & Processing Forum:

This competition is intended to be a fun way for you to improve your imaging abilities and a way for you to see many new images with a variety of equipment. All imagers are welcome and encouraged to enter.

Each month a single object will be selected for the competition by the winner from 2 months previous. Having a one month delay allows voting and selection of the next object and will give a full month's time for entries.

The winner of each competition gets to choose the next object and their image will be included in the Hall of Fame message thread. There are no other prizes.

Please include your imaging details such as location, date, telescope, guiding, exposure time, etc with your submission.


1. Have fun! Support other contestants and be polite with your comments.
2. All entries must be captured within the same imaging season. For example, if the December target is the Orion Nebula, you must use images taken during the current winter, not any other year.
3. Image size is limited to 800x800 pixels and 200k in size.
4. Any equipment is allowed to be used in the images including rental equipment; with the only exception of DSLR, since we have another forum specifically for DSLR.
5. All image taking and processing must be done by your team, including equipment setup.
6. Each person may submit only 1 entry per month. However, you may edit your submission and replace the image with a newer one if you wish using the Edit function.
7. Winners will be selected by forum members, the one which receives the highest number of vote will be the winner.

Please submit your image in this thread, comment can be made in the same thread as well.

Well, have been working on this object all summer and still collecting data. This is described in more detail on Astrobin, but basically:

59 x 750s RGBs + 9 x 3600s H-Alphas.

Processed in PixInsight using Harry's script for integrating H-alpha... not much color otherwise.

This is my wide field version showing many fainter galaxies in the background. I often see this with more blue but according to Xcalibrator there is not that much there.

Scope is AG Optical 12.5" F/3.8 newt.
QSI640wsg8 camera with Astrodon filters gen2
Lodestar guider
AP1200GTO mount

20 x 5 min Lum 1x1
18 x 4 min ea RGB 2x2

Imaged at my observatory under yellow/orange skies.

Might as well fill out the field with one more. Took this back in early July. Supernova 2013bu (detected April 2013, aprox. mag 16.5 here) can be seen as the top "star" forming the triangle just below and to the left of the core. It faded away pretty quickly.

Here is my entry. I have had very little time for imaging, but managed some time on this object. It was taken with my homemade astrograph, based on a 12.5 Zambuto mirror. Time was limited, but roughly 3 hours of L and 1 hour each of RGB. My camera is a FLI ML8300M with Astrodon filters.
