  1. Removing Noise

    Noel Carboni as you may know works for Adobe so has inside information on Photoshop. The noise reduction packages were tested and optimised on deep-sky images (as well as others) which is why they work so well on DSOs. Greg
  2. Removing Noise

    I do the same as Ken Greg

    This is today's (21/05/2021) EPOD - but you saw it on here first Greg
  5. Street Lights For and Against

    I was at a Council meeting where they were discussing changing all the Sodium street lights over to LED. And the only question that came from one of the local councillors was "Would the new lamp posts be the same colour as the old ones". That was the depth of their understanding. Greg
  6. Street Lights For and Against

    As someone who is up all night and sees what's going on - the only thing the street lights help at 1 in the morning are the foxes to find their way home. I have never seen anyone walking around at that time. Greg
  7. Street Lights For and Against

    Oh - and by the way. It was excellent here for a while when the LED street lights were turned off around midnight - then my skies were pretty dark indeed. But what happened? Enough people complained that they didn't feel "safe" and so the Council kept the lights on all night. You just can't bloody win here Greg
  8. Street Lights For and Against

    I have some very impressive before and after shots too. Before was Sodium street lighting and the sky was a BRIGHT sickly yellow. After, the sky (to the eye) looked much darker and you could see many more stars. Here's the rub. Astroimaging wise the sky is WORSE with the LED lighting than it was with the Sodium lighting!!! Has Parker lost it? How can it possibly be worse when you can see far more stars by eye - and that of course is the argument the local Councillors use when convincing the plebs that LED lighting is so much better for the night sky. Well the problem is that manufacturers made really efficient light pollution filters which took out ALL the Sodium light pollution. You cannot have a filter for the LED lighting as it is broadband. So what you find is that Sodium filtered skies are DARKER to the CCD than the skies where LED street lights are fitted. So even though the LED lights are better shielded, enough bounces back off the ground, trees, whatever to actually make the skies worse than they were before. Greg
  9. 1st Images from my new 450d

    Good work!!!! Greg
  10. M87 Jet!!!!!!!!!!!!!!!!!!!!!

    Thank you Tim - my present the last few years is just to be above ground, that'll do me Greg
  11. M87 Jet!!!!!!!!!!!!!!!!!!!!!

    Hi Ray, No inversion or colour manipulation, just a bit of careful processing with the DD filter and some curves at the end to reduce the overall brightness a LOT. Greg
  12. M87 Jet!!!!!!!!!!!!!!!!!!!!!

    Here's the whole image with M87 blown up as an insert. Greg
  13. M87 Jet!!!!!!!!!!!!!!!!!!!!!

    Those of you used to seeing my work may think (at first sight) that I've lost the plot with this one. Got out for the first time in MONTHS last night and did an hour's worth of imaging with the Hyperstar III on the C11. 12 x 4-minute subs of M87. Processed using the Digital Development Filter (instead of a bunch of curves) and I managed to pull out the JET!!!!! May look unimpressive - but I am really happy with this one Greg
  14. Pelican

    Minimal processing done Tim. Greg
  15. Heart nebula composite

    Yep - to get the whole thing in it's a 2-framer with the Sky90s, that's like trying to image IC1396 (which is also huge). Greg
