The August 2020 Challenge is now open. The target is M20 The Trifid Nebula. To reduce the number of stickies, please submit your entry to this thread.

 

For those having troubles locating the target here is a post that will help locate near by objects.

 

The Rules will remain pretty simple:

 

      Your Equipment

      Your Data, Captured This Season

      Your Processing

      One Entry Per Member

      Only post your FINAL image

 

To increase participation over such a diverse group, the winner will be selected by random drawing. Please feel free to start a thread requesting guidance on your entry prior to submitting it, the whole purpose of this challenge is to learn and compare on a common target. Entries must be submitted by midnight eastern time on August 31, and I will try to announce the winner sometime on September 1.

 

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

 

Please display an image in your post, not just a link!!

 

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

 

Let The Games Begin

 

**Disclaimer** - 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.

Wow M20 will be quite a challenge at this time of year.

I think 34 deg above the horizon is it maximum and its there now.

I'll start you off. 

 

Captured two weeks ago from my front drive with the RASA8 and ASI533MC Pro OSC.  The cooler had just died - it is now on its way to China for repair - so this was shot at ambient (around 30C).

102 x 30 sec subs, Celestron LPF for the RASA, 20 darks, Minimally processed in PixInsight.

27 degrees max for me. I have one from 2019. I will have to sit this one out. Looking forward to others work!

Dears,

 

my contribution, taken June, 12 this year. The object culminated just 15° above the theoretical horizon. As a have a low mountain range in the south the actual distance was less than 10°. Not a big surprise the stars are bloated.

Remember this challenge says images of this season. Not this month. So yes, it will be difficult for people living more north to image this month but if they imaged it at any time this summer then it is fine to submit.

I am quite far north myself, so this is a difficult target, but the combination of emission and reflection colors is really beautiful, I think. As I am currently traveling I do not know if I can image it this season. I find Elf‘s image really encouraging, showing what a great result is achievable from my latitude, where the nebula reaches only 15 degrees altitude.

This picture was taken 5/25/20 with the ASI071MC-Pro camera, 62x1' at 200 gain, and an 8" f/4 reflector, on a CEM-60 mount guided.  Stacked in DSS, developed in Star Tools, Gimp, and Starnet++.  At the low altitude the colors don't quite align, probably due to atmospheric dispersion, but still the beauty of M20 remains.

trifid-webRGB-session_1-csc-mod-SC-St.jpg He is mine. What I got before it went behind the trees in my yard. Only 30 minutes of 3 minute subs, but it still came out ok.

 

Taken with a QHY168C and a 6 inch astrograph on a guided Atlas EQ-G process with APP and PSE19

 

Thanks

Joe

A real "challenge" this month for me. Shot between the trees August 7, 9, 10 for a total of two hours of integration using mono ASI1600MM Pro. The individual RGB subs were processed and combined in Pixinsight.

 

My equipment, acquisition  and other information is listed on AB in the link along with the higher resolution pic.

 

Thanks for looking.
