  1. Hey guys Having been inspired by everyone else's fine images of M81 & M82 recently, i decided to go back and re-process my shallow stack of the same objects. I shot this back in early Feb, and at the time only decided to swing the wee 80mm scope around to it after my main target for the night (the Rosette Nebula) had disappeared behind the neighbour's house, so i wasn't able to go deep on it. I haven't bothered to return to it since, but i was never fully satisfied with the processing on it (even though it can obviously only be taken so far, given the short FL and exposure) so i decided to have another go (plus the weather's been crap recently!). I'm much happier with the star colours and background now (at least to my eye) and i seem to have eeked out a bit more detail in the galaxies themselves, especially in the jets of M82, where i was able to stretch the Ha data a lot more before blending together a mix of it and the Red channel from the RGB data. Although in hindsight i may have gone too far with the sharpening in M82. Be interested to hear what you guys think. If i was going to add more data to this, i would definitely prioritise the RGB over the Ha (i think i need a much bigger scope to properly shoot Ha on this). Oh yes, and try to remember to shoot at ISO 200 next time, and not 800! lol. Here's the new version: And here's the original: And finally, here's a crop of the new version, just to display the galaxies a bit bigger:
  2. Hi! My next 3 images from December 2015, May 2016 and February 2016. All taken with Nikon D7200, SW150/750 and guided HEQ5Pro at Lisow (35km from Czestochowa, Poland) BTW I've got a question... Which settings are better for D7200? Higher ISO (eq. 1600) and 300sec frames or lower (ISO400 or 800) and 480sec light frames? M81 and M82 (May 2016) 7x300s ISO800 3x dark M33 (December 2015) 11x300s ISO1600 only 1 dark frame M1 (February 2016) 3x300s ISO800 3x dark (only 3 light frames because of very poor weather and high clouds) Tomek
  3. M81 Bodes Galaxy and M82 Cigar galaxy. Taken last night 23rd April despite a bright moon. 120 x 60 sec lights, 40 darks. No bias or flats as I'm having a bit of problem with my flats at present, they seem to make things worse not better. Taken with Canon 1100d unmodified with a Celestron C8 on an HEQ5-pro. Processed in DSS and Star Wars (Sorry Star Tools). The Star Wars connection?, well you can see that M82 is better illuminated while M81 is on the Dark side. It was reported that a supernova was observed in Bode’s Galaxy in 1993, however it is much more likely that M81 was the location of Alderaan. destroyed by the Death star in the first 1977 movie and we viewed this event 12 ish million years later given that M81 is 11.8 million light years from Earth. If this sounds a bit far fetched remember that the story was set "A long time ago in a galaxy far, far away" so it sort of fits. If you don't believe this then all I can say is that "I find you lack of faith disturbing"
