  1. Hi All, I was lucky enough to have one clear night in between cloudy and rainy weather. It happened to be a moonless night, so between 9pm and just past midnight I grabbed the final subs I needed to finish the NGC1365 barred spiral image (still to be finished-processed) and after those subs were done I wanted to start to image the whole of Orions Sword using my 80mm f6.25 refractor. I captured an hour of 210 second subs, an hour of 180 second subs, 30 mins of 30 second subs and 15 minutes of 15 second subs all on the full spectrum modded Canon 40D at ISO800. For the final processing I selected only the best subs, and thankfully most were near perfect (for my average standards), resulting in me only throwing away a total of 15 minutes of data. The next night I get a another imaging session at Orions Sword (hopefully still when the moon is not lighting things up), I'll grab a stack of Halpha and OIII data to add to this project. I'm curious what the narrowband added to this RGB will result in. Clear skies, MG
  2. My wife Janie is very heavily into cross-stitch and produces beautiful work from photographs (normally dogs!) using patterns that I produce for her using special software. Her latest project is from one of my deep sky images and one of her favourite objects, the Orion Nebula. The 'resolution' is a pretty appalling 216 x 216 stitches but when hung on the wall and viewed from about four feet away, it will look like a photograph. As usual, I have produced a mock-up for her showing literally every stitch that will be sewn using 82 different silk colours! For the fun of it I will post up WIP images but here is the mock-up for starters (the image might need to be clicked on to show the stitches rather than just an interference pattern!):-

    Image of the whole of Orions Sword in RGB using a 80mm f6.25 doublet refractor. I captured an hour of 210 second subs, an hour of 180 second subs, 30 mins of 30 second subs and 15 minutes of 15 second subs all on a full spectrum modded Canon 40D at ISO800. For the final processing I selected only the best subs which was about 2 hours 15 minutes of data.

  4. Well the cold front stays-yay! I'm observing all the time now under crisp, clear dark skies and tonight the HH showed itself with no filter , with best view given from the 18mm ES 82 with and without the UHC. The 20 Lunt did well in both modes but I figured its time for the big guns...the 25mm TV plossl/ZZ and an excellent copy of the Astromik Hb. Both these eyepieces gave a high contrast view of the HH with the Hb. No snout with the 25mm TV so now the zoom. I zoomed in, I zoomed out but I got no snout Well thats that then! An interesting feature caught my attention in the Rosette nebula using the 30 ES 82/UHC. At the top of my newts view in the EP a very nice, highly contrasted, detached section of billowing nebulosity was seen. It measures roughly 1 deg across and about .25 deg high. I looked connected to the main body by a small bit of nebulosity. This feature really caught my attention tonight, what a prize! The Running Man, this is a favorite and tonight the conditions were great for seeing the dark lanes that make his shape up. The other night when observing him I tried the 18mm BCO and bam!! excellent superb view giving great enhancement to the shapes. Tonight under similar conditions the 12.5mm Tak ortho went in and again much enhancement. What I'm saying here is that if dark transparent skies are about and youre observing this object- put those orthos in there, you may be shocked at what you see! Many Many more objects observed including the Jellyfish nebula and an Eskimo nebula that showed it radial filaments and 2 toned green color. What a night! A fine 2 hour session I must say.
  5. Now i dont know if i'd call this cheating - but i did a monochrome version of this because it just feels so much easier to bring out the little detail in this image without creating too much background noise in the colour version . I think i like this more than the colour version edited with PI LE, CS5 Unmodified Canon 50D, Sigma 50-500mm APO F/4.5-6.3, SW EQ5, 30 x 120s ISO 800 Sorry but cant remember what focal length this was taken at! taken in a very light polluted aberdeen
  6. Hi All, Before setting up on to a new target, I managed to spend a couple of nights on exposing the Orions Sword through a HAlpha and OIII 7.5nm filters to add to the pure RGB image I posted earlier. I got 10 x 900s for each Halpha and OIII across two nights. I mixed 30% of Halpha from Red into the Red RGB channel, green and blue from OIII channels into green and blue channels in the RGB corresponding channel. So here I'm sharing the final result... I've moved on to imaging Barnard 33 so I think this will be my final version of the Orion nebula for a while. Another thing is that the contrast and color levels look very different on my PC screen when comparing to the iPad display so I've posted both versions, the darker version is optimized for my iPad screen where the less contrasty version looks better on my PC LCD. For my future postings here is a small survey... which one looks better on your screen/display? Thanks for looking, MG
  7. From the album: Deep Sky Imaging

    Image of the “Running Man” Nebula near Orion Nebula, taken in natural color through my 8" SCT at a focal length of 2032mm using an astro modded and cooled Canon 40D DSLR. Object ID: Sh2-279 - NGC1973, NGC1975, NGC1977, NGC1981 I captured around 90 minutes of sub data on 2nd March but a lot of the data from that night, about 60%, was poor with drift and star bounce due to over compensation with DEC corrections/DEC Backlash setting being too aggressive, and rejected as a result. During the next night the subs are coming out nice and stable. The above image consists of the best 12x30s, 12x60s, 24x120s, 20x180s & 12x240s ISO1600 subs, total time of 2 hours and 54 minutes.

  8. 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
  9. Now this is the way to ring in the New Year. I took advantage of our unseasonal like crystal clear skies we are enjoying and forgo the traditional festivities and spend it under the stars. I was finally able to make another dream come true and at last image the Orion Nebula with my iOptron Zmount and AT65EDQ. With an amazing 5 hour session that wrapped up at about 3 in the morning here's the results. Let me know what you think of the processing. 15x5 seconds, 15x30 seconds, 15x120 seconds, 15x300 seconds. Each series went thru DSS and then blended together in PS4 and tweeked in LR4. The ORION Nebula by Leveye, on Flickr
