  1. 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

    M42 - The Orion Nebula, plus top left M43 - De Marian's Nebula (aka "The Running Man Nebula"). This is 30 x 30 second exposures, plus 22 x 320 second exposures in an HDR composite, taken 11th Jan 2014. Again I was battling a nearly full Moon as we seem to get nothing but rain around here when the skies are fully dark! This image was processed entirely in PixInsight. I hope to get some longer exposures to try to capture more of the surrounding dust.

  4. Hello all, I'm starting a new thread for this since the hydrogen data is rather old and it has been reprocessed since I posted a while ago. Now I finished the acquisition of O[III] too. Or sort of, I planned more, but clear nights were so rare that I decided to process what I had. The image was done in "3 pass" data over the area. That means that I acquired 3 sets of images covering the same area and combined in the end. First 2 in hydrogen, the last in oxygen. First set consisted of 3 panels in portrait mode for the top area and then I wanted to extend them to the bottom so I shot another 2 panels in landscape mode. I knew that I could get a higher SNR so I shot 4 more panels in landscape mode. Each panel consists of 30-31 subs, each sub 300s. Then I started the acquisition of O[III] which needed light pollution and moonlight conditions than the Ha required. Top panels contain 30 subs, but the bottom ones, only 20-22. Each 300s. Luckily there's not much oxygen in that area so I could get away with less subs. I also took some 10s-30s frames for M42's core. For the framing, I created a quick mosaic of the same area. For the final alignment I shot an image somewhere close to the center of this area. I can't remember if the initial register was done in APP or Registar - for the first pass, but for the next ones it was done in Registar. I removed the gradient manually in each stack with APP and then I created the mosaics for each pass same with APP. The 2 Ha passes I then blended manually 50%-50%. For the processing, I tried to stretch both Ha and O[III] to the same levels and I combined them manually in some 60-40/70-30 ratio for a layer which I used as lum. The colours were Ha - reddish, O[III] - cyan-blue. I spent a lot of time trying to control the big stars, the O[III] filter has poor coatings and, together with the ASI1600s non AR coated sensor, I had much brighter reflections than with the Ha filter. And I tried to raise the oxygen levels selectively around the flame and NGC2023, but the flame is really dim in O[III]. Don't know what other details in the story I forgot, this project drained me a lot of energy. Camera was ASI1600MMC, cooled to -15C for the first pass and to -25C for the ones following. Gain 139. Canon 300 F4 L IS lens with a lot of aberrations towards the edges. AZ-EQ5 mount guided with a 200mm lens and an ASI120MM, with varying seeing. 1.5-2.5" RMS guiding error usually. APT for capture, PHD2 for guiding, Registar for each night initial alignment. DSS, APP, Registar, StarTools, GIMP for processing. I started shooting early in October and I wanted much more, but Orion already becomes less and less visible from where I image and hides beyond the house. Ah, yes, I image from a yellow-pink light polluted area. Thanks for reading, thanks for looking! Comments and suggestions are appreciated.

  5. Captured back in early October, I didn't pay quite enough attention to the framing - I should have moved the camera up and right a bit and I could have gotten the whole belt in the picture... the headline stuff is in there though, M42/M43, Horsehead and Flame etc 10x 200 second subs taken with a modified Canon 650D through a Borg 55 f/3.6 (focal length 200mm). There's a load of red stuff in there that needs more exposures (or slightly longer ones) to show more off so I will redo this one and frame it correctly... or do a mosaic of Orion or... well, it'll depend on the number (or lack) of clear nights!! Unfortunately there are haloes on Alnitak and Alnilam, I may have a solution for the next time I cover this area Processing wise I'm going to have to sort out shorter exposures for the Orion Nebula and longer for the rest...

  11. Happy to see the stars again last night, though cirrus clouds were everywhere. With some luck I got some (short) time with lower cloud density and I pointed the scope towards the Orion. 32x30s usable longest subs, 15x10s for the core and I also used 14x20s taken on the 25th to remove the big halos caused by the brighter stars seen through clouds. I could not expose longer, I only had my DSLR and my EQ5 mount, no intervalometer. The second picture contains some narrowband data I had, which I added in a very small amount to the RGB image. Ha as red and O3 as G and B. This is taken through another lens and it is just an experiment. The scope seems to perform very well. I can't wait to see what I can get in proper conditions, but it seems that I have to wait a while for this. Clear skies! Alex
  12. It turns out I can not acquire more data until this challenge ends. I present you therefore what I have until now. It's a 5 panels mosaic in Hydrogen alpha. 3 panels in portrait mode, at the top. And 2 in landscape mode, at the bottom. Each panel is made by 30-31 subs of 300s and for the Orion nebula core I have a few 15s subs. All subs are taken with the ZWO ASI 1600 MMC, cooled to -15C, and 139gain. The lens is a Canon 300 F4 L with a lot of distortions caused by the IS element. Compared to the images I was taking on other targets until Orion rose enough, the focus was good since the beginning and remained ok during the nights. Mount: AZ-EQ5. Guiding with a 200mm lens. Software used: APT and PHD for acquisition; DSS, APP, Registar, StarTools and GIMP for processing. I plan to acquire 4 more Ha panels in landscape mode to cover the same area to increase the SNR and then to move to O3 and LRGB. A lot of work this winter.

This led me to wonder if there was a way I could display my images on a single page together with a few notes on the target object as well as few technical details of the capture for those who might be interested. What I came up with a "scrapbook" like page that combines all of these three elements in a single PDF sheet ( or jpeg image) that ultimately I might combine together to form a PDF book that I can share online or send to friends and family. In the meantime, I thought I might post in this thread each page of my work-in-progress towards volume 1 of my Astrophotography Scrapbook. Any and all comments, observations, suggestions and constructive criticisms will be warmly received. Cheers Mike ps. The pages have been sized to fit full screen on an IPAD

  15. Just gone ten o'clock and I notice a clear sky (well I didn't recognise what it was to start with, pin [removed word] points of light against a dark background - I wasn't used to it). Scrambled the scope to a state of readiness by 22:15 hrs and pointed it towards the Great Bear, which now dominated the Eastern sky and had risen quite high. An easy find was the galaxy NGC 3877, very close to Chi Ursae Majoris. At magnitude 11, this was not easy and looked like a small linear subtle wisp with averted vision which became more obvious with the 8mm X-Cel ED eyepiece. A short star hop to the East led to another galaxy NGC 3893, a larger wide oval haze which I found slightly easier to see. I then began another star hop from Gamma Ursae Majoris (Phad) via M109 which was not as obvious as I had previously noted, and eventually landed on NGC 4026 which was perhaps the most prominent galaxy of the night. It was much more condensed than the others and very slightly elliptical. Sadly some light cloud rolled in over the Eastern sky, so I switched to Orion just past its best in the Southwest. M42 and M43 looked mighty fine with the UHC-s filter on the 8mm eyepiece, although I couldn't pick up much texture. Something which I had managed previously on a slightly clearer night. Never the less, I managed to sketch it for the first time and will post a little later. The clouds had thickened up by now and more of the sky was now obscured. My scope had also misted up a little so I called it a night. Not the longest session ever but i'll take it right now! __________________________________________________ ______ Observing Session: Friday, 1st February 2013, 22:15 hrs to 23:10 hrs GMT VLM at Zenith: 5.1 New - Revisited - Failed

    This is my first play with Photoshops 'Layer' command. An original single frame capture was copied to a new layer above my stacked and manipulated image. I then used the history eraser tool to remove the area around the trapezium to show the adjusted layer below but kept the original brightness of the trapezium stars from the single frame layer - if that makes sense?!? That way I can show more of the nebulasity but have kept the trapezium stars from burning out.

  20. M42 and M43: my first target using the new Orion SteadPix EZ. Once all set up, Orion's SteadyPix EZ works really well (though it can be tough swapping lenses on a dark night). This pic is actually just one shot made into three layers: 1 layer for is the entire picture, one layer with the main body of M42 cut out, and one layer consisting only of M43. I stacked and processed them on the iPhone with the Photoshop Mix application. I found that playing with the stacking transition settings (Blend) yielded the best results when using the following options: Normal, Brighten or Punch. Cutting away portions of the various layers allowed me to expose just the portion I wanted, so the dimmer nebulousness came through without destroying the rest of the photo. For me iPhone afocal AP is the way to go... until I can trick my wife into allowing me to buy a an EQ mount, guide scope, imaging OTA, CCD sensors, etc... 13 January 2018 Memphis, Tennessee, USA Sky Watcher 10" Dob iPhone 8 Plus Sky: NELM 4.5-5 Bortle Class 7-8 Edit: Used a cheap bluetooth shutter remote to actually take the photo
  21. Hi Everyone, This is my best M42 image till date. Every year I take a shot at this wonderful object and every year it teaches me something new. I started using Pixinsight only two days ago and the results are dramatic. I do take more care while processing and it has given me wonderful results. C&C welcome.
