Astrobdlbug Posted January 21 Share Posted January 21 (edited) Hi everyone, been doing a few bits and pieces of imaging but no real big projects - you may have noticed I have been using my OSC camera and giving broadband a go from my location - using IDAS D2 filter, despite its halo generation in conjunction with the FF/FR. Hower for this image I used a 1 hour unfiltered image of Orion I took back in November 2021, same camera, different telescope, I used registar to match the images and Photoshop to blend in the large stars that suffered halo disease... This is purely OSC image, no additional Ha channel has been added. Seeing was not so great as there was high humidity and this morning we had freezing fog. Overall quite pleased given conditions and total integration time, I used Rus Croman's tool suite and SPCC to get an accurate colour representation and did not use curves to alter the balance in any way. I am quite impressed how much dusty stuff the ASI2600MC hoovered up in a relatively short 3 1/2 hrs . Hope you enjoy my annual pilgrimage to The Great Orion Nebula, M42, Bryan Image Detail Dates: 7 Nov 2021 · 19 Jan 2023 · 20 Jan 2023 Frames: NO FILTER : 30×120″(1h) IDAS LPS-D2 2": 107×120″(3h 34′) Integration: 4h 34′ Edited January 21 by Astrobdlbug 8 Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted January 22 Share Posted January 22 Looking good Bryan. That’s the target I’m currently working on with exactly the same IDAS D2 filter but ASI183MC much smaller sensor instead with the Redcat 51. Doing many (lots) of 30 second subs on it. Probably it’ll take all year to process! 1 Quote Link to comment Share on other sites More sharing options...
Astrobdlbug Posted January 22 Author Share Posted January 22 Thanks Terry, hope the weather holds so you can finish your M42 image. 9 hours ago, TerryMcK said: Doing many (lots) of 30 second subs on it. Are you planning any longer subs to capture the dusty stuff or is it 30s for entire image ? I did a M42 image using L-Extreme filter in Nov’21 and did a series of subs 15s, 30s, 60s, 120s and used Photoshop to combine the stretches and create a HDR image from Triangulum out to the dust - it’s an interesting exercise in processing and although not ‘representative’ of how we observe M42 with its very bright core it does allow a greater appreciation of the structure right at the heart of the nebula. Having said that I didn’t do that with this image - I used HDRmultiscale Transform followed by a masked LocalHistogram Transform to balance the core with the outer wispy gas.

TerryMcK Posted January 22 Share Posted January 22 I was doing some 60 second ones last night - got 2 hours in - but the forecast for the next few days is dire. So putting it on hold until the weather improves. 1 Quote Link to comment Share on other sites More sharing options...

Thanks Tony, I’ve been messing about with the image this afternoon and gone back to some old friends in Photoshop - layers, masks and astroflat Pro - lifted up the dust a bit and done a bit of HDR on the core Triangulum stars using some 15s and 30s subs I took unfiltered with same camera. Here’s the revision Edited January 22 by Astrobdlbug 5 Quote Link to comment Share on other sites More sharing options...

Here’s the revision Nice job! I do love the fine-tuning flexibility that PS gives. I’m still not in any rush to take on a new learning curve with PI yet.
