  1. Thanks once again to FLO & IKO for this opportunity to work with quality data as the awful weather continues to dominate in my part of the world! Processing information below image. Each channel DBE Balance channels with HistogramTransformation I like to try something different each time I process an IKO image and this time I used PixelMath "Dynamic narrowband combinations" to combine as SHO (based on the post at https://thecoldestnights.com) Multiple small stretches with HistogramTransformation then a MaskedStretch Remove magenta stars with pixel
  2. Thanks for the kind words, I really need to do more Lunar imaging as I found it so rewarding. DSO just seem to be an endless source of frustration at the moment.
  3. First time out this year as the weather in Edinburgh has been so bad. The Seeing was great but the moon was as 77% so Deep sky wasn't an option (apart from some Ha later on) so I decided to try some Lunar imaging for the first time in ages. These are all taken with my Sky watcher 120MM ED DS Pro with a Teleview 3X Barlow (f22.5) and an ASI290MM (usb3 version). Stacking in AS3! (1000 frames per capture stacked to 12%), Processing in Photoshop including Topaz DeNoise AI. Copernicus (4 panel mosaic) Montes Apenninus and Eratosthenes Archimede
  4. Well done to all (Especially David), really enjoyed all the different versions/styles, really inspirational.
  5. A huge thank you to to FLO & IKO for this, weather has been awful here so was great to have some quality data to work with. Each channel DBE Small stretch with HistogramTransformation Starnet Create SuperLum using all 3 starless images Balance channels with HistogramTransformation PixelMath to combine as SHO HistogramTransformation MaskedStretch LRGB Combination using SuperLum Remove magenta stars with "Invert->SCNR->Invert" SCNR LocalHistogramTransformation Stars layer PixelMath to combine each channel (before starnet) for stars image
  6. Thanks for all the kind words, my motivation is really struggling this year as the weather conditions are so bad, doubly so when you have to set up/tear down every time. I haven't seen too many SHO versions of IC405 and they are usually super saturated so I was aiming for a more subtle approach - no sunglasses required Rob.
  7. The Flaming Star nebula (IC405) Captured over several nights in September processed in the HSO (hubble) palette with RGB for the stars. I had intended to get more data for this, particularly in OIII but the weather hasn't been playing nice! I haven't had any clear nights for the last two months so I am going to call this done for now and return to it next season.

  8. My goal was to show the huge dynamic range captured in this magnificent data set of M17 using a “non-standard blend” to really highlight the main nebula and background nebulosity. A huge thank you to FLO & IKO for this, it's been nothing but clouds here. [Processing steps detailed below image.] Pixinsight Slight Crop to remove some stacking artifacts DBE (only a small amount of gradient to remove) Ha, OIII, SII => stacked as MasterLum Noise reduction and Deconvolution were not used as the data is so good Channels combined with PixelMath Red: Sii 80% + Ha 20%
  9. A huge thank you to FLO & IKO for this, it's been nothing but clouds here so was great to have something to work on. My goal was to create a classic Hubble palette version and show the huge dynamic range captured in this magnificent data set of M17. Keeping the green and aqua tones were vital in this image to really emphasise the richness of signal in all three channels. Pixinsight Slight Crop to remove some stacking artifacts DBE (small amount of gradient to remove) Ha, OIII, SII => stacked as Master Lum Noise reduction and Deconvolution were not need
  10. I have an Evostar 120ED with the sesto senso on the fine tune side of the focuser so should be similar. My step size is 575 (calculated using SGP's instructions) and this works well for me, giving nice V curves during auto focus runs.
  11. Love it, although it looks to me like he's set himself on fire !
  12. Lol, ok a teddy bear jumping over a fiery skull. thanks Pixies, it probably works well as a rorschach test
  13. Thanks Andrew, spooky indeed, maybe it's just me but I have never been able to see it as a teddy bear.
  14. Sharpless2-171 is an emission nebula which is part of NGC 7822, in the constellation of Cepheus. It is often called the "teddy bear nebula", however viewed in SHO with this rotation it looks (to me) like a screaming skull, or the head of the Balrog from lord of the rings! Perfect for Halloween.

  15. A huge thank you to to FLO & IKO for this, it's a rare treat to work with such fantastic data especially in OIII & Sii. I wanted this image to show the magnificent background Ha nebulosity with an RGB look while also using the SHO data to highlight the crescent 'bubble' in a complimentary colour so that it stands out while still looking natural. To achieve this I created two versions (plus a third for the stars) and blended them together. Full processing details are listed below the image.
