The February 2024 Challenge is now open. The target this month is the Horsehead Nebula. To reduce the number of stickies, please submit your entry to this thread.

 

The Rules will remain pretty simple:

 

-Your Equipment
-Your Data, Captured This Season
-Your Processing
-One Entry Per Member
-Only post your FINAL image. Please display an image in your post, not just a link!!

 

NO general discussion in this thread. Your post should only contain your image and appropriate info. There is a separate thread for discussion.

 

To increase participation over such a diverse group, the winner will be selected by random drawing.

 

Entries must be submitted by midnight, eastern time, on February 29, and I will try to announce the winner sometime after March 1.

 

If the selected winner does not reply and pick a target with-in 3 days of the winner being announced, the Mods will then select the next target.

 

There is now a companion thread that runs parallel with the imaging challenge each month. This thread will be for general discussion on the corresponding months imaging challenge target. This thread will be very informal and relaxed and will be treated just like any other thread in the forums. Here is where you can post questions on processing, get help finding the targets location, post a preliminary "final" image to get feedback, etc. The only thing special is that I will be pinning it every month and each months companion thread will be titled in the same way for easy finding and searching. Since this is informal the mods will NOT be starting this thread. We will leave it up to the general membership. So it could take a couple days for someone to start it and for a mod to pin it. So please be patient if you don't see it up day one. Who ever starts this thread please PM me with a link to the thread so I can pin it.

 

Whoever starts the companion thread should title it to match the following: Target Name - Techniques and Progress Discussion  For example: Rosette Challenge - Techniques and Progress Discussion

 

Once the companion thread is post, please DM me with a link or put in a mod alert and I, or a fellow mod, will get it pinned.

 

Note: If I am late announcing, gently nudge one of the moderators in a private note, it helps.

 

I hope everyone has fun with this one, and with that,

 

Let The Games Begin

Nice, finished this just a week ago.

I couldn't decide if I like SHO or OHS better, so I processed both versions.

For once the forecast was wrong about a cloudy night and instead we had the first clear night in weeks here on the Oregon Coast!  I just happened to shoot the Horsehead too.

Here is my entry for this month. I would try to get more Ha for this, but it is too low too early for my horizon this late in the season.  I was only able to get 50m of H, and 30m each of R, G, & B, however this 2h 20m image has more detail than my previous OSC image that had about 2x as much time on it.  The H filter and mono camera was a real game changer.  Still, the short integration time hurts the final image.  The JPG might look ok since it was scaled to 50% before cropping to 1600x1200, but there is still plenty of noise for you to enjoy on the full size/res version here:

 

https://drive.google...iew?usp=sharing

 

Equipment used:

  • Camera: ZWO 2600MM
  • Filters: ZWO Ha (7nm), R, G, B
  • Scope: Zenithstar 73, 0.8x flattener (345mm focal length, f/4.7)
  • Mount: EQ6-r Pro
  • Guiding: OAG-L, ZWO 174MM
  • Exposure: H 300s-10, R 120s-15, G 120s-15, B 120s-15

Finally got a clear night for the first time in a long time.  Framed this as Orion's Belt, processed it as a black and white Ha due to the low total time/high noise.
