Welcome to the Cloudy Nights Imaging/Sketching Contest!

Over the years, we’ve noticed we have some exceptional talent in our forums, and we’ve decided that we would like to show it off. Each month our readers will choose an overall winner, and that photographers image will be displayed on the front of CN for a month. The winner will also be awarded an official Cloudy Nights t-shirt courtesy of Astronomics.

How to enter:

Please visit our forums and submit an image/sketch in the appropriate forum, each forum will have a "sticky" thread called "Imaging Contest Submissions".

Images may be submitted to the contest threads in the following galleries:

Beginning Imaging
Film Astrophotography
DSLR and Digital Camera Astro Imaging and Processing
CCD Imaging and Processing
Solar System Imaging and Processing

Moderators are listed by the forum name, and additionally their name or handle appears in green. Please contact them if you have any questions.

Each month, 6 images will be chosen from each gallery for the readers of that gallery to vote on. The winner will be placed in a site wide poll for our users to determine which is an overall winner.

See the individual forums and moderators for additional details and questions.

Rules are subject to change without notice.

Contest Rules:

1. Images submitted in a particular forum must reflect the focus of that particular forum.

  • Entries in the DSLR forum must be images captured with a Digital SLR or digital camera
  • Entries in the CCD forum must have been captured with a dedicated astronomical CCD camera
  • Entries in the Film Astrophotograpy forum must have been captured with a film camera
  • Entries in the Solar System forum must be of subjects within our solar system
  • Entries in the Sketching forum must be an image of a sketch
  • Entries in the Beginning Imaging can be of any astronomical subject as long as they are captured with a camera of some sort and do not violate any other rules.
2. In order to provide a level playing field and to encourage participation by novice imagers, entrants in the Beginning Imaging forum who win the semi-finals poll in the CN Imaging Contest a total of three (3) times - or who win in the finals regardless of the number of times they have won the semifinals - will have demonstrated sufficient proficiency at astrophotography to no longer be considered a "beginning imager". Such an imager will be considered to be a "graduate" of the Beginning Imaging Forum, and are encouraged to compete in the other imaging or sketching forums. The exception to this rule will be in the case of an entrant who wins the semi finals poll in Beginning Imaging as an uncontested entrant. An uncontested winner in the semi-finals will not have their win count toward their "graduation" as a beginning imager unless they also win the overall contest.

3. Entrants may submit an image for consideration in only one forum participating in the CN Imaging Contest. Entrants submitting images in more than one forum must choose a single forum to enter in or else all submissions from the entrant will be subject to disqualification.

4. 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.

5. Please include the equipment used to take the image. Scope/Mount/Camera/Focal reducers/Barlows...whatever, as well as your name, the time / date and your location.

6. Entries are limited to absolute maximums of 100,000 bytes in file size and 800 pixels X 800 pixels square. Entries that do not meet this criteria will be disqualified.

7. Links to any other versions of contest entries are specifically restricted and will subject the entry to disqualification if included.

8. There will be a separate sticky thread for Contest entries. Please do not post comments in the entries thread its just for these wonderful images you all will be submitting.

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

10. You must be the owner or co-owner and operator. You must setup, align, take the exposures and process them yourself. No pay by the hour rent-a-scope images will be allowed.

11. A given user can only win in the finals once every 3 months.

12. Voting for the individual polls posted in the forums will be no later than the 5th day of the month. Forum voting takes place from the 5-8, finalist pictures / poll is posted no later than the 10th, and voting takes place from the 10-15. Finally winners are posted to the front page on the 16th of each month.

All right, I'll throw in my 2 cents :-)

Saturn image taken March 16th around 23h30UT, using my Celestron C9.25 at F/27 - DMK21USB camera and Astronomik R,G,B Filters.

This image is a composite of 7 RGB runs, in Red & Green the best 2000 of 10000 frames, the best 3000 of 15000 frames for Blue. DMK21 camera was run at 15fps, so these images span tens of minutes - any surface detail that isn't cloud bands is smeared.

Not that Bart doesn't deserve to win (nice image, sir!), but are you going to allow him to go unopposed?

Shame on you! <big fat grin> You've only got a few hours left!

O.k., think this Venus might be quite nice for the contest.

Posted Image

Venus about 1 week before inferior conjunction at 19° altitude (still daylight observation, sun 6° above horizon).
8-in Newton @ f/19 on Losmandy G11, DMK21AU04.AS with IR 1000nm filter.
Bad seeing, only 20 usable frames out of 2000 stacked with registax 5.

Best regards

Here's Saturn with just one degree of ring tilt, the Cassini Division is barely visible inside both east and west ring ansas. The northern polar and temperate regions contain several beautiful teal-blue colored belts and zones, the North Equatorial Belt-north is a rich green color, while just to its south lies the golden North Equatorial Belt-zone, and below this is the greenish colored North Equatorial Belt-south. The razor sharp and ink black ring shadow spans the entire width of the sandy colored North Equatorial Zone, curving as it approaches each limb. Saturn's sharply angled globe shadow is visible on the back ring located behind the planets western limb. A couple large swirling cloud tops are visible inside the South Equatorial Zone, and to their south lies the large (red or salmon colored) South Equatorial Belt, it's split by a thin light zone, and south of these are located many colorful light and dark (tropical/temperate) belts and zones, next is a wide copper colored band the South South Temperate Zone, and finally the South Polar Region and South Polar "Olivet" Cap are indeed olive colored. The (950 mile diameter) moon Rhea is totally eclipsing the Sun and casting its shadow on the dark green cloud tops of the NEBn.

Meade 10" SCT, Celestron's Ultima barlow (extented to F/44), no (UV/IR or IR Cut) filters were used so that I could capture the full color spectrum. Philips SPC900NC webcam, frame speed: 5fps, shutter speed: 1/5th second, recording: 10m 40s. Processing: Registax v4, stack size: 2,222 frames. Post processing: MS Digital Image and IRIS. Image aquisition: 1/22/09, 9:29 UT from the "Chiefland Astronomy Village", Florida.
