Orion mosaic - 2 seasons - M42, IC434, NGC2024, M78

Recommended Posts

Posted (edited)

I've been processing this image for quite a long now.

I started acquiring data the last season when I only managed to shoot 3 panels with the Canon 6D through the Esprit 80 for a total of ~7h.

This season I restarted and I added more data and covered a wider area. So a mix of portrait and landscape panels were planned and shot with the same scope and camera. Now every pixel represents at least 3-4h of integration, some have more.

All the above were shot from Bortle 2-3 sites where I traveled sometimes even for an hour of exposure.

To the RGB data I added 17.5h of Ha, same story with the panels. Some were oriented N-S, others E-W. These were shot with the SW 72ED and the ASI1600 from home and Bortle ~7.

Then I figured out I still had time and I planned and shot 9 more panels of luminance with the 72ED and ASI1600, each consisting of 1h of exposure.

I combined all of these into an image, processed it and for the Orion nebula and Running Man nebula I also blended some data I shot last season with the 130PDS and ASI1600 from home.

Below it's my first final version of all data combined. You can watch it in full resolution on astrobin: https://www.astrobin.com/full/jni0w8/ or Flickr: https://flic.kr/p/2iBGUXq

Here are some intermediary stretched stacks

Outstanding. I especially like the first intermediary stretched image, looks very natural and delicate.

Great stuff! Very interesting to also see the intermediary stacks!

Thank you too!

Here's one more intermediary image I used for aligning the FOV. All framing was done manually, rotating the scope in the rings and slewing the mount slightly.St-avg-65697s_stretch_025_crop_grid.thumb.jpg.fee48e8a4f29affdf107173556b4d748.jpg

Hi Alex. Incredible image! It was also your first take on it last year that convinced me to buy a Canon 6D! Great camera!

Thank you, David! It is indeed a very capable and robust camera and quite cheap used. In the far future I'm thinking of modifying it, once I buy one of those new Canon mirrorless for everyday use.

      Since I am very new to this, I struggle a lot. Especially when observing planets and also recently deep sky objects. My telescope is an amateur telescope and its almost 11 years old (The telescope was re used a year ago). During summer of last year I took photos of Saturn,Jupiter and a month ago took photos of Venus and Mars. About 2 days ago I stumbled upon a new thing in the sky, (Unfortunately, I didn't take a picture). It definitely was in the Orion constellation  as I had observed Betelgeuse and the 3 stars that were close to each other. After a couple of minutes later I saw 2 stars next to each other and another two which were on top of the other star, surrounding these set of stars were a blue-ish and grey-ish colour at the same time. I had done some research and many people told me it was the trapezium cluster found in Orion. I honestly don't know. Any ideas? Thanks.

      First image from my new NEQ6 Pro driven mount, all other images before this were static.
      Sky Watcher 200P prime focus, 10x 60's lights, darks, bias and flats. ISO 200
      Bortle 6
      Yes I know there is a plane track through it.

      I recently posted a picture of B33 using my Optolong L-Enhance filter which was not too bad, a bit red, for my first time trying out Pixinsight. Last night I managed to get nearly 2 hours using my IDAS D2 LPS filter and after watching many Youtube videos I've managed to get the following using my Esprit 100ED and modded canon 450D, 21*300s Lights, flats, darks and bias frames. I think I'm starting to get my head around post processing.

      This is my first image using my Optolong L-Enhance dual band filter and the free version of Pixinsight, which does certainly take a lot of time to learn. I know it's not going to win any prizes but I'm quite pleased with it. Especially after all the time it's taken me to produce Master Darks, bias and flats today, luckily the weather has meant I've been stuck indoors most of the day.
      This is with my Esprit 100ED, Canon 450D, 24 * 300s Lights, 100 flats, 100 Bias & 30 darks. I do struggle with post processing as I'm not very artistic, so all advice on where to go forward with this will be appreciated. I am hoping to get some more subs with my LP filter to add to it.

      This may be an artifact, but I took this shot of the Orion Constellation from the Canary Islands and it showed a small nebula around Beteleguse. Do you think this is real? The shot was taken with a dual band filter which brings out the Ha.  I initially assumed it was a camera artifact, but I took more shots with different camera positions and it was still there.  There are some on-line articles about such a nebula. My first reaction was to edit it out, but I think it might be real and only visible because Beteleguse has dimmed by over 50%.  What do you think?
