SGL 2023 Challenge 3 - DSLR and Mirrorless Deep Sky Challenge


Recommended Posts

Modern astro cameras with set point cooling are superb instruments for night time imaging.  However, modern DSLRs and mirrorless cameras aren't too shabby either.  So here is a chance to see how well these general purpose cameras can perform when faced with the challenge of capturing deep sky astronomical targets.  For the purposes of this challenge deep sky means any object beyond our solar system.  Cameras modified by removing the IR filter are eligable but not any with fitted electronic cooling.  Although labelled DSLR and Mirrorless all cameras are permitted other than those specifically designed for astroimaging.  You can use a Box Brownie if you like (now that would be a challenge!)

Please include details of equipment used and other capture information.

Start date 1st March 2023

End date 31st May 2023 

No entries will be accepted after this date.

 

As previously the winner and runners up will receive an SGL challenge mug showing their image along with a virtual medal-of-honour for their SGL signature.

Please post entries directly into this thread

To keep the thread manageable for the judges please do not post comments about entries, emoji reactions are welcome of course.

Ok, I'll bite 😄.

This is my take on the heart & soul nebula. Shot during three nights, from 3rd to 6th of March, with moon almost full, from Athens (bortle 9+), and was actually intended as a test for my new lens.

120x300sec subs, Canon RPfullspectrum, Optolong L-extreme, Canon FD 300L 2.8 @2.8, Pegasus nyx-101.

I was quite happy how M 51 turned out, given the modest specs of the gear and software used:

  • TS-Optics 60ED (360mm), AZ-GTI with 120mm guide scope
  • No filters, standard (unmodified) Canon EOS800D
  • Single night (April 21st), 57x 150s, ISO 800
  • Stacked, cropped and processed with Siril, finalized with Photoshop

M63 - The Sunflower Galaxy

As posted in the imaging forum https://stargazerslounge.com/topic/409905-m63-sunflower-galaxy/ .

 

I was a little unsure whether to enter the widefield or cropped version, but the widefield won out as I love just how many faint fuzzies are in this field. The DSLR has picked up galaxies in the PGC catalogue and other even fainter catalogs. I can see 2, maybe 3 distant galaxy clusters. Second image with the new scope, imaged across 5 sessions; 10 frames on 9th May, 32 frames on 12th May, 28 frames on 13th May, 45 frames on 15th May, 39 frames on 17th May. Some discarded for the final stack.

Canon EOS 800D (Astro modded) +  Starfield 102ED with 0.8 reducer. No filters.
Sky Watcher HEQ5 with Belt Mod
ZWO ASI120mm Mini + ZWO 30mm F/4
Frames - 144 x 300s (12:00:00), ISO 400
Calibrations - 50 bias, 40 flats, 6 darks.

Stacked in ASTAP, processed with SIRIL, AstroDeNoisePY and GIMP. Minor crop for stacking artifacts, FL = 570mm.

My attempt at the rather small (in my FoV) M 101:

  • No filters, standard (unmodified) Canon EOS800D
  • Two nights (May 12+13th), 112x 120s, ISO 800
  • Stacked, drizzled and processed with Siril, finalized with Photoshop

First ever attempt at deep sky imaging, and first time using photoshop, was aiming for the North America Nebula... I missed but got the Pelican Nebula next to is although its very faint.

 

Olympus OM-D EM10 Mkii, 300mm F6.7 with pig iron Astro clear light pollution filter

Star Adventurer GTi + ASIair mini 

ZWO ASI120mm Mini + Svbony 30mm F4 120mm guide scope

Frames 18 x 180s (00:54:00) ISO1000 (I had another 7 but bloody satellites...)

Calibration 10 bias 5 darks

Taken from Lytham St Annes coast on 25th May (well, 26th technically) Bortle 5 sky

Stacked in deep sky stacker and finished in photoshop
