  1. Seasons greetings, all! HiloDon and I are at it again with another seasonal delight for our friends here at SGL! HiloDon provided the stellar images and I created the musical landscape and produced the video. There's a little surprise near the end! Hope you enjoy! For all who observe, have a Merry Christmas and Happy New Year! Reggie
  2. A close up of this summer gem. Approximate exposure times: Red: 59 x 60 s Green: 33 x 60 s Blue: 41 x 60 s Ha: 25 x 120 s Data from the LT archive; processed in PixInsight
  3. Had great skies last night - first decent clear night of the Autumn season, so made the most of it with a first try at the Dumbbell Nebula: (Skywatcher 200p, EQ5 GoTo unguided, Canon 450D @ISO 800, 16 x 120s subs, 8 darks, 8 bias, processed in DeepSkyStacker + GIMP) Taking the subs went smoothly enough, but I struggled with the post processing. The stacking went fine, but I was finding it very hard to get the colours to look right in GIMP. I was messing around with levels, contrast, colour enhance. In the end the only thing that gave half decent results was doing a colour enhance, then adjusting 'colour temperature'. That seemed to restore some sanity. I feel like there's a lot of decent data in there, but it's hard to coax it out. Any tips for bringing out decent colours for the Dumbbell Nebula? I'll have another crack in GIMP tonight!
  4. Sadly, this project is currently stalled by the atrocious weather but at least I have had one uninterrupted night of imaging to start the ball rolling! I'm aiming for a bi-colour rendition combining Ha and OIII data at 3nm. I have a lot of data capture to go but it's a fair start. Image Stats Mount: Mesu 200 Telescope: Sky-Watcher Esprit 150 ED Pro CCD Camera: QSI 683 WSG-8 Sampling: 1.04”/pixel Guiding: OAG/LodeStar Filter: Astrodon 3nm Ha Exposure: 10 x 1800 sec Date: 31/07/17 Calibration: Bias, Darks & Flats Full Frame Cropped Frame

    M27

    From the album: Photos from Bury

    M27 the Dumbbell Nebula. Processed using DSS. Hardware details: Camera: Nikon D200. Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 21 x 3min at ISO 800, Darks: 20 x 3min 20sec at ISO 800 (from dark library), Lights and darks separated by 30 sec intervals. Flats: 40 x 1/40s at ISO 800, Bias: 30 x 1/8000 at ISO 100 Date of capture 30/04/2016. Increasing cloud stopped imaging after about 1 hour, some wind, seeing was reasonable. Guiding was not great in RA but fine in DEC, PA was ok - I think I might have knocked the scope at some point in the night. I increased the saturation by 20% and manually aligned the colour channel histograms. No drizzling was done here - it was crashing my laptop.

  7. Hi all This one was processed using Ha as monochrome Luminance layer. Ha 2x15m 2x10m 31x5m, binx1, 3h25m integration time RGB 5x5m each, bin1, 1h15m integration time, altogether 4h40m. Andy
  8. M27 or Dumbbell Nebula taken on 3 July 2014. A second attempt as the first was thwarted by dew on the lens and the sky getting lighter. 98 x 15 second exposures at ISO 6400 and 42 dark frames. Processed in Deep Sky Stacker, PixInsight and Photoshop CS6.

    M27 (Dumbbell Nebula). Processed using DSS. Hardware details: Camera: Nikon D200. Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 39 x 3min at ISO 800, Darks: 20 x 3min 20sec at ISO 800 (from dark library), Lights and darks separated by 30 sec intervals. Flats: 40 x 1/40s at ISO 800, Bias: 30 x 1/8000 at ISO 100 Date of capture 30/04/2016 & 08/05/2016. Increasing cloud stopped imaging after about 1 hour, some wind, seeing was reasonable. The second night was less cloudy but transparency was much worse. Guiding was not great in RA but fine in DEC, PA was ok - I think I might have knocked the scope at some point in the night. The second night gave better auto guiding. I increased the saturation by 25% and manually aligned the colour channel histograms. I stretched the red colour histogram more that green or blue to increase its contrast. This helped bring out some of the nobbled structure within the nebula. 2x drizzling was done on DSS.

  10. Another reprocessing while waiting for the weather to improve. The data for this was taken on 30th June 2015 from London. This time I used the processing tools in Nebulosity and Maxim DL in order to get what I think is a better image than before. 19 x 2 minute subs at 800 ISO 6 x dark frames 11 x flat frames 24 x bias/offset frames Guiding by PHD Calibrated and stacked in Maxim DL Post Processed in Nebulosity, Maxim DL and Photoshop
  11. Not my first post here, but my first DSO that I can say I'm truly happy with. Comment and suggestions welcome. Thanks for looking. Mike

  13. Back in 2013 i captured a nice image of this nebula that i was very pleased with. However, it strongly lacked red as my unmodded 550D filtered it all out. So here the other day, trough some fog, i managed to capture some Ha data with the help of the QHY5L-II-M and a Baader 7nm Ha filter with the explorer 200. Exposures were limited to only 60 sec as i was capturing unguided, and even then i had to throw away half my subs (i really need to have my mount chacked and serviced...). Captured using Firecapture, with gain set at 1000, and peltier cooled the camera to about -20c. RGB data from 2013: 1 hour 45 min @ ISO800. Ha data from this week: 47x 60 sec. Gain 1000. I think the Ha data helped a lot to bring out more red color and details. What do you guys think? Original RGB from 2013: Ha data from the QHY5L-II-M: New HaRGB:
  14. Absolutely stellar seeing last night for a few wee morning hours despite the forecast my autoguiding graph at one point looked like the heartbeat of a deadman finally nailed the balance of the DEC of my mount let me know what you think of the processing 5 lights 3 Darks 420 seconds each iso 400 20 biases at 1/8000th stacked in DSS and tweeked in PS5 and LR4

  17. Hi all Another M27, this time with H-alpha added: I set out to capture the outer shell, no matter how little or much. It may not be perfect, but I'm happy with it. 2x15min, 2x10min, 31x5min, RGB 5x5 in each channel, bin x1, altogether 4:40h of exposure. This is an HaRGB image, Ha integrated into red, and the separate HaR used as luminance. Andy
