Mar10 CN Imaging/Sketching Contest Submissions! new
      #3655241 - 03/01/10 08:16 PM

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
Sketching

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.

Specifically:
  • 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.

I made a sketch of the nice solitairy crater Hercules (69km wide). I used my old 4" Polarex Unitron for this sketch. Magnification was 300x (5mm Plossl).

This is the raw sketch, made behind the eyepiece. HB Pencil on white paper. Original size of the sketch is 4" by 2".

There's a little more than a day left to enter, and Roel's sketch is too big in file size to pass muster at the poll. If he does not fix it (and no one else enters) then Sketching will not have representation in the finals!

Here is my entry:

Date: 3/16/10
Time: 1:14am MST/ 08:14 UT
Location: Pit n Pole, Rush Valley, West Desert, Utah
Conditions: Clear, cold, humidity over 70%
Seeing: III-II Antoniadi Scale; 8/10
Object: NGC 3190 Spiral Galaxy;
Mag: 11.2
Size: 4.1'x1.6'
RA 10h 18m 1s
Dec +21 50'
Instrument: XT10
Eyepiece: 13mm Stratus @ 92x, 2x barlow @ 184x

Object: NGC 3193 Elliptical Galaxy in Leo
Conditions, Seeing: See above for NGC 3190
RA 10h 18m 4s
Dec 21 54'
Instrument: XT10
Eyepiece: 13mm Stratus

This is a faint spiral galaxy that appears tilted but face on. It may be a dust or dark lane that is riding across it. Core is SE and is bright and large sitting in the dust lanes. The more I observe the object, the more detail comes out. The dust lane is disturbed with mottling showing a possible dark lane running through this galaxy. I would confirm it visually as a dark lane and astro images confirm this as do my observing friends. I do like how I captures this in the sketch.

NGC 3193 is a small elliptical galaxy just east-north-east of NGC 3190. It is a rather bright at my viewing location here at Pit n Pole, and sits next to a ninth to tenth magnitude star. It is a dull white with no discernible features at 92x. This elliptical does provide a nice contrast with NGC 3190 though.

Here is a sketch of M82.
M82 has some dark lane and bright area.
And I observed strange structure in North-Western edge.
Very faint nebulosity is there.. It remind me melope's shape

[M82 sketch]


[Description]


But any photography of M82 doesn't have such structure.
I don't know it is true or false.
Have you ever seen this structure before?

Below is M82's photo. (google search)



Date : 2010.3.13
Time : 8:10~9:30 (UT)
Location : Cheonmunin-maul, Kangwon-do, S.Korea
Seeing : 5/5
Limiting Mag. : 5.0 → 4.5
Temp : -4C
Equipment : Discovery 15inch dobsonian
Pentax XL 14mm (136x)
White conte & pastel, black paper

Hi Nightwid: I can only take one image for the contest - which one of these is your submission?

Nightwid's image also exceeds the forum and contest image size limits at 676 x 872 and will need to be resized to be eligible.

I'm sorry..
I want to submit below image.

Here is a sketch of M82.
M82 has some dark lane and bright area.
And I observed strange structure in North-Western edge. (lower right area of galaxy)

I don't know it is true or illusion.

I observed Saturn through my 10.1" Newtonian at medium to high power magnification (120X ~ 240X) on several evenings from February 28th through March 2nd, in effort to see some detail in the rings and surface cloud banding. Seeing was medium to marginal at times through the evenings. Using Sol Robbins template and other images from the web to accurately proportion the rings, I rendered this 19” X 25” pastel impression showing about what is seen in a good medium telescope if one stands back say 25 feet from the full image on a standard computer screen. Saturn’s disc was sketched at 7 ¾” at the equator. The Cassini division was easily visible and the crepe ring only hinted at high magnification at 240x through a 5mm Super Plossl eyepiece.

The imaginary foreground as if seen from Saturns moon Titan was added as a dramatic finishing touch.
