  1. Looks very nice - plenty of the dark dust picked up, but I'm not sure how well that will print. Whenever I get something printed, the faint stuff always seems to get lost. By North, do you mean "down" - because I think your image might be upside down. Easy to turn a print around, though
  2. You've done a great job with the central core! Nice one.
  3. I realised how badly I had combined my channels last time I posted this back in 2018. Holding back on the Ha channel has really brought out some extra structure I had completely destroyed with my previous hap-hazard approach. So here it is again - it's a Bi-Colour combination of Ha and Oiii as a 2 panel mosaic. Acquisition Hα: 2x24x600s Oiii: 2x17x600s Equipment Optics: MN190 Camera: 460ex Mount: AP Mach1GTO Guding: Orion mini 50mm guidescope & QYH5L-ii
  4. Very impressive results for completely untracked capture! What was the actual exposure length of each sub? Must have been very short!
  5. Well my images are total crap then!! Awesome detail and I like the improved colour balance, especially since you improved the stars.
  6. Fantastic result. Great work on the processing! Would love to have a try for the outer shell myself, but not if it requires 23 hours - that'd take me months!
  7. A very fine image! The original seems the best to me, nice and natural. Good to see the difference that registar has made - I normally get the stacking software to align my channels but that's not perfect.
  8. What a fascinating object! Thanks for imaging and posting it.
  9. Really nice. I like very much the colour and carefully handled background field
  10. Nicely done - I know just how difficult this is to process - there's a huge difference in brightness between the core and outer regions. The second version looks very similar to me, on my screen. I'm almost tempted to suggest you've posted the same image twice!?
  11. When drift aligning my mount, I aim for below 4' (that's about 0.07 degrees) however I have a permanent pier and wouldn't want to do that every night!
  12. Very nicely done Olly. Compared to my own attempt at M101 (which also looks too cold in comparison), it shows just how much further the galaxy extends than I thought it did!
  13. Thanks! Here's a tighter crop:
  14. Hello, everyone. Sorry for yet another M51 but it's always an enticing target, being so high in the sky and I haven't tried it with my current setup. It's been more than a year now since my last post - I've had a bit of a break from the hobby due to various reasons, including the recent birth of our daughter! Baby + astronomy = one very tired dad One victim of this equation was my Hα layer, which was taken with the Bahtinov mask in place! So this is an LRGB image which I've processed with very basic techniques in Photoshop. I decided to get decent amount of RGB to try and bring out the fainter colour in the background fuzzies etc. The RGB layer turned out almost as strong as the luminance layer! However, this is far from the best M51 you'll see - I really don't know how others achieve so much impressive detail. I threw away a lot of luminance subs that were taken before I drift aligned, which helped improve the detail but only so much. Perhaps I need to revisit collimation. Atik 460ex Skywatcher MN190 L: 32x600s RGB: 3x15x600s Calibration: Flats only (Total: 12.8 hours) Thanks for looking!
  15. Hi! There's a lot to love about this image. Really nice, fine detail showing off a great field of interesting galaxies. Perhaps your colour is the more genuine one?
  16. Seems I need to read some more tutorials or finally invest in Pixinsight - I still find colour balance tricky with PS.
  17. Very nice one Sam - I love the wide field, but still plenty of detail in there too. You didn't get on with the Quattro 10 then?
  18. Excellent in terms of detail and colour, but also composition. Makes for a lovely image!
  19. Thanks! I thought I'd attach a 100% crop of the galaxy (0.94"/pixel) - which is fairly unforgiving for most images, especially mine. The answer is infrequently and with a collimation cap - I have a laser collimator but have never used it. When I received the 'scope it was fortunately well collimated and I only adjusted the primary. Still happy with the collimation, although the 460ex isn't a huge sensor.
  20. *of the year* - my second ever image was awful! ? Thanks though - yes I really like the combination of MN190/460ex.
  21. Having only finished my first image of the year about a week ago, incredibly I now have a second one. We should try to remember that we do get decent weather in the UK sometimes after all! NGC 2841 is a neat little galaxy in Ursa Major. I say little, but it's actually similar in size to the Milky Way. The tidy appearance suggests that it hasn't had any recent interactions with its neighbours and apparently has a low rate of star formation. There's a nice variety of faint fuzzies in the background, which I particularly like about this area of the sky. Capture L: 38x600s RGB: 3 x 20x300s Total: ~11hrs Equipment SW MN190 Atik 460ex AP Mach1GTO Guiding: QHY5L-ii + 50mm finderguider
  22. Stunning result! Your first LRGB? The colour balance looks great, I wish I could process my own LRGB data this well.
  23. Very nice. You now have even more sky-hours than the rest of us!
  24. Looking like you may have some really nice data but I can't help but notice the galaxy has an unusual appearance, almost as if it's through stained glass window? Perhaps some of the processing steps have been a little too harshly applied?
