  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

    Orions Sword

    From the album: Deep Sky Imaging

    The whole Orion's Sword in RGB and 30% HOO added to the channels. This image was taken with a modded Canon 40D through a 80mm F6.25 (500mmFL) Bosma Beta RE Refractor.

  3. From the album: Deep Sky Imaging

    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.

  5. 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

    This exposure of the Orion Nebula region is really just a quick and lazy session since I didn't want to waste a clear night by doing nothing and the scope was already setup and focused so I wouldn't be spending much time on setup. I also didn't have a plan for imaging another object it seemed like a good idea being a bright and easy object to image. I already imaged this object in the past, but by comparing the setup, procedure and improved tracking accuracy of the past together with the now cooled 40D, I know that the result would have been an improvement if I would have dedicated the necessary exposure time, through the necessary NB filters. This image all consists of RGB/OSC, IRCut filtered, 31x15s, 32x30s, 16x60s, 10x90s, 11x120s ISO1600 subs.

  7. Hello astronomers, This exposure of the Orion Nebula region is really just a quick and lazy session since I didn't want to waste a clear night by doing nothing and the scope was already setup and focused so I wouldn't be spending much time on setup. I also didn't have a plan for imaging another object it seemed like a good idea being a bright and easy object to image. I already imaged this object in the past, but by comparing the setup, procedure and improved tracking accuracy of the past together with the now cooled 40D, I know that the result would have been an improvement if I would have dedicated the necessary exposure time, through the necessary NB filters. This image consists of all RGB or OSC (through the IRCut filter) 31x15s, 32x30s, 16x60s, 10x90s, 11x120s ISO1600 subs. I am not prepared to spend subsequent nights capturing narrowband subs on "Orion's Sword", at least not this year... perhaps next time M42 is in the sky and only if I reach near freezing temperature cooling on my sensor. Clear skies, MG
