  6. From the album: Deep Sky Imaging

    The subs exposed for this image were done almost a year ago and I completely forgot about them. This image consists of a total of 16.5 hours exposure time on SII, HAlpha and OIII data over multiple nights of imaging. Imaged through a BOSMA 80mm refractor at 500mm focal length (f6.25) using a full spectrum modded Canon 40D DSLR.

  9. Hello Astronomers, I got the Topaz Labs Detail and DeNoise PS plugins and I have to say that they are great... noise is literally seek and destroyed without effecting the detail.... After playing with it for a couple of days I say that the plugins are definitely definitely worth getting. I reprocessed my M16 data from July this year and used topaz detail and denoise to try to get some more detail... I also applied the denoise filter to a JPEG image of the horsehead nebula from last year and, well I think the results speak for them selves. Clear skies, MG
  10. Hello Astronomers, During the week when I was imaging the Helix Nebula, I was exposing it when it was east of the meridian. So as it hit 15 degrees past the meridian and the meridian flip happened, there was no guide star in the OAG FOV so I had the option to pack up and continue imaging another day or try for another object and hope for a guide star. As the sculptor galaxy was close to the location I slewed to it (with favour western horizon selected in the CGEM settings) and to my joy when the sculptor galaxy was framed a 1/3rd of the frame to the edge there was a guide star in the OAG... WOO HOO ... and so a second object imaging continued. After getting 3 nights worth of ISO400 10 minute RGB subs, I found that after processing the image was very amber at best.. almost sepia... and no matter what I done to it it always looked too green or purple at certain parts... just didn't look right. When I eventually got a chance, I was going to image some pure blue subs to add to the image to correct for the amber look, but as luck would happen, forecast was for at least a week of clouds and rain... this week was no better BUT I did see a break in clouds the other day with a 3/4 FULL MOON!!!! I couldn't afford to let this opportunity go to waste so I imaged NGC253 through a Halpha filter to cut out the moon glow... remembering that when imaging through Halpha in the 40D there is a lot of data in red (of course) and about 30% as bright in the blue channel.... I thought that I could use that added to blue as well as add some halpha to red and perhaps reveal some nebulosity. I only managed 8 x 15 minute subs before clouds started coming and 4 out of those were usable... here is the result. Thanks for reading my babble.... MG
  11. 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
  12. Hi All, After a 8 month break due to moving I finally had a chance to do some simple Deep Space imaging. This image is of the Tarantula Nebula in the Large Megallenic Cloud (NCG2070). This is imaged using my modded Canon 40D at F10 2032mm using a Nexstar 8SE on a CGEM mount. The image consists of 12 x 5 min subs, 5 x 10 min subs and 10 x 1 min subs, all in RGB through a IR Cut filter. Currently I'm working on using the PEC feature on the CGEM, and after I've spent a few hours before trying to work out how it works... when it got to past midnight, I was ready to call it a night but decided to frame up on the Tarantula and give it a go... I thought it's not to shabby for a quickie, so I'm sharing it. As far as PEC goes, next time I get to do some astro, I should have NexRemote, PECTools and PHD to give me a average PEC training from 10 cycles... hopefully it'll improve the guiding accuracy and hence detail in my 2000mm imaging close up images. Thank for looking, Mariusz

    While waiting for the Tarantula to get into imaging position to grab some Ha and OIII subs to add to the previous posted image, I decided to do a quick 47Tuc image. Unfortunately when centered, there was no guide star in the OAG at the current setup, and I did not want to alter the position of the OAG since it was still setup from a previous session to continue on NGC2070... so some unguided subs of the glob had to suffice... it's only 15 x 60sec, 15 x 30sec and 15 x 10sec subs in ISO800 at F10 using the modded Canon 40D. Seeing wasn't the best but surprisingly being unguided the stars were round, fat but round... I guess it's only 60 seconds at longest sub and PA was quite accurate.

    Barnard 33 Region

    From the album: Deep Sky Imaging

    Horsehead and Flame nebulae around the star "Alnitak" in "Orion's Belt" in the constellation of Orion. The nebulae are located approximately 1350LY for Flame nebula and 1500LY for the Horsehead curtain glow nebula. Alnitak is a bit closer at about 1250LY and is the source of light for the glow of the nebulae. The Horsehead nebula is a cold dark nebula silhouetted against the pink hydrogen alpha emission nebula IC434. The Horsehead shape is just the shape of the nebula that blocks that part hydrogen emission of IC434. This image was taken using a full spectrum modded Canon 40D. Image consists of Hbeta, HAlpha and OIII data as well as RGB taken through IR cut and neodymium filters across multiple nights in November and December 2015.

    The Lagoon Nebula (Messier 8, M8 or NGC 6523) is a emission nebula in the constellation Sagittarius, and is estimated to be between 4,000-6,000 light-years from the Earth. This image was taken with a full spectrum modded DSLR through a 80mm refractor for a total exposure time of 1002 minutes through SII, HAlpha and OIII filters.

    This collection is of my images of Venus I captured during December 2016 and February 2017 which shows the change in phases as Earth catches up to Venus in the orbit around the Sun. The pictures where cloud details are coming through were captured through a UVenus (UV) filter on the clearer atmospheric condition evenings and used as the blue channel. The rest the channels are IRPass 685nm filter as red and luminance (IrCut filter) as green. All were captured using a DMK618 through a 14" Dobsonian.

    Image of the area around the Tarantula nebula, imaged in RGB. This image consists of a few hours of 5 & 10 minute subs in RGB at ISO400. The Large Megellanic Cloud is visible in the lower right of frame where as the Tarantula is in the upper left. Image was taken with a 80mm refractor at 500mm FL.
  18. 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
