Recommended Posts

Start date: 1st November 2021

End date: 31st January 2022

The format of this challenge is a little different in that it will comprise three sections with one outright winner for each.  You are welcome to enter more than one section.

1) Widefield landscape images featuring Orion. 

2) Images of the Orion asterism without including a landscape foreground.

3) Deep sky images of any of the objects within the Orion constellation  boundary.

Prize: A personalised mug for the 3 winners featuring your image kindly provided by our sponsors FLO :) and a virtual trophy for your signature.


All data must be captured and processed by you (no collaborative entries). 
Data must be captured during the challenge start & end dates. 
Multiple entries are allowed but please start a new topic for each entry. 
Multiple submissions of the same image, processed differently, will not be accepted.


To enter please post within this topic, do not start a new topic. Please post as much information as possible - when it was taken, how it was captured and processed, etc. The info won't necessarily be used for judging but will help fellow SGLers looking to learn and improve their knowledge and technique.

After we 'put the clocks back' I look forward to my first views of Orion before 'ridiculous o clock', as he rises majestically above our hedge that borders our backyard to the south. Mrs H always says " Orion is peeking over the hedge". This image was captured at 2:00am on the 3rd of November 2021.

My first attempt at a widefield version. Canon 600d camera on a Star Adventurer mount. Sigma wide lens at f=14mm. and F5. Stack of 7x 240sec RAW lights (plus darks and Bias) at ISO800.  Stacked using DeepSkyStakker, colours and levels adjusted and image cropped using APS . Noise and light pollution reduced using Topaz AI and GradientXterminator.  

I am currently trying out the GradientXterminator plug-in and am dropping big hints to Mrs H that my birthday is in November and that this would make a great gift for an old astro-imager!207511872_Orionpeekingoverthehedgewithframeanno.thumb.png.526bdc62f6525a803abd4638dd3860d0.png

Here's mine. Mono, but from nb Hso data. Shot in a single 3 hour morning this week. I used my asi1600 and efw with a heath Robinson attachment to my samyang 135mm.

Processed in affinity photo. I've posted the colour and Mono versions on the dso topic, but I'm going with the mono for the comp. It's a bit different, and I think would make a nice print?  I've tried to keep the dark dust clouds.

First time with the GT71. My first real scope. Been doing astro for about 1 year, DSLR and tracker

Fornax LT 2, D5600 unmodded unguided
3 min x 16 at ISO 400. Lost 90 minutes of data (30 x 3 min) because i left bahtinov mask on the GT71 :( 

Taken evening November 5th in Wadi Sab Sab about 300km NWW of Dammam. 

Ambient around 25c, bortle 3, no filters, have to say I'm amazed the Fornax can track 3 mins at this focal length. Getting accurate PA seems to help, I use AAP just for PA

This is my entry of M42 taken on the 02nd of November 2021. I`ve only been doing astrophotography for 5 months and still and learning the ropes, I think I need to focus more on learning to post process. 


Taken in Bortle 5 with my 150pds on an unguided EQ5. My camera is a stock canon EOS M3, as it doesn't have the port for an intervalometer I used the canon camera connect app and an intervalometer app on my phone.   

60x 45 s lights at ISO 800

30x 45 s Darks

68x bias 

56x flats. 

Stacked in DSS and processed with Gimp.

Here's an entry under category 1: 1) Widefield landscape images featuring Orion. 

Taken at the autumn Kielder Star Camp just moments before I hit the sack (part of the reason why can be seen sliding over from the right of the picture). This  is a view of Orion and my neighbour John's setup - still going at the time as far as I could tell..
