  2. As expected Orion was a popular target for this challenge but we also had some wonderful wide field images from a variety of sky locations. As always the judging was difficult with a spread of votes. 1) Pipnina - The California Nebula and surrounding area As well as a nice capture of the Cal Neb the dusty detail is superb 2) Orion and his easterly neighbours - Gerr What a magnificent expanse of sky. You can get lost looking at all there is to see in this image. 3) Ursa Minor - Red Chilli Sometimes "less is more". This delicately processed image leads you further and further in. The star colour is beautiful and the dust areas subtly rendered. Red Chill also submitted an annotated version of the image https://content.invisioncic.com/g327141/monthly_2023_12/Polaris_1.jpg.6a6d1b676dfd9c857783974234311d2a.jpg Well done to everyone who submitted an image. There are other excellent images on display in the challenge thread.
  3. Start date: 1st March 2024 End date: 31st May 2024 Very simple. We are looking for images showing the night sky with a landscape foreground. The image must be taken with the same camera and lens/scope combination but stacking is permitted as are star trails. If you have any questions please feel free to PM me, this is much preferred to discussions within the thread. RULES All data must be captured and processed by you (no collaborative entries). Data must be captured during the challenge start & end dates. Entries after the end date will not be included in the judging Multiple entries are allowed. 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. The thread is for image submissions only, please do not respond to entries other than by using emojies.

  6. A small number of entries for this challenge but the quality was outstanding. As always, some tricky calls for the judges. 1) Venus What a wonderful daytime image! Kon used IR and UV filters mapping IR to red, UV to blue and created a synthetic green. Beautiful! Taken with a hand controlled 8" dob!!! 2) Geoff Lewis - Jupiter with IO transit Io transit with the GRS just coming into view. Sensitively processed. A great image! 3) Nigella Bryant - Uranus Uranus has been well placed during this challenge but it is a long way away! A fabulous long focal length image. Well done to everyone who took part
  7. Nasa's "Astronomy Picture of the Day" on 23/01/2024 was a remarkable image covering a huge area of sky and revealing a multitude of deep sky objects https://apod.nasa.gov/apod/ap240123.html Of course, very few of us have Arizona type night skies but lets see what you can come up with. This challenge is to capture the night sky and the deep sky objects hiding there. It can be a single wide field image or a multipanel mosaic. The only rule is that the same camera and scope/lens should be used throughout. You can use different filters if you wish. The judges will be looking at the depth of the image, the sheer number of objects visible and also the aesthetic quality of the image. You could choose to annotate your image but if you do this please only use annotations which appear when you move you cursor over it. Part of the fun is for people to see how many objects they can identify for themselves If you have any questions about the challenge please message me, please do not start a discussion within the thread Start date 2nd February 2024 End date 30 April 2024 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. -- RULES 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 make a fresh post within the thread.

    Welcome to SGL Jane. I hope you are enjoying retirement! I finished as a GP 6 years ago and haven't looked back! If your visual impairment mainly affects the macula you should be fine for deep sky observing. In fact observers have to train themselves away from using their central vision towards using "averted vision" engaging the more light sensitive parts of the retina. You have picked a nice scope!

  11. As always some terrific entries with a huge variation in the types of image submitted. This has made the judging quite tricky since there was quite a wide spread of votes. However we now have our three winners along with a special mention for another. 1. IB20 Moon Halo 2) High cloud with ice crystals have created this effect which must have had IB20 hurrying to grab his camera. A very striking image 2. DaveW Pomona Dock, Salford A very mundane title for a spectacular image. Capturing an image like this takes a lot of planning and perseverence. Superb 3) Derbyshire Dave - The moon over Florence Cathedral The cathedral reaching up to the the heavens, what a wonderful image! During the period of this challenge we had a very rare appearence of nacreous clouds. The clouds are made up of very fine ice crystals, much smaller than normal ice clouds. They require very cold temperatures to form and are more commonly seen in extreme northerly latititudes. They reflect light from a recently set sun producing a luminescent effect and can contain a spread of colours. Scotty1 managed to capture this in the image below. It isn't one of our winners because although the moon is in view it is the cloud that steels the show and this isn't a cloud challenge! Well done everyone who entered. I am sorry if you are amongst those who submitted a wonderful image and aren't in the frame, in a parallel universe the selection could have been completely different!
  12. Wowser! That is glorious.
  13. Sorry, I didn't make it clear in the intro, this is a deep sky object challenge.
  14. This is a pure narrowband challenge. No broadband LRGB component and no monochrome images. Any combination of narrowband signal is permitted. Duo and even triband filters are now popular for use with one shot colour cameras and images using these are welcome. Permissable bands are Ha, OIII, SII and hydrogen beta. If you have any questions please message me rather than posting in the thread. Start date 1st January 2024 End date 31st March 2024 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.
