  1. I used Gimp software, after opening I selected to duplicate the image so now I have 2 of the same image in the Layers/Channels the top image and change the Mode from Normal to this point move the opacity slider to adjust the effect, 'sometimes' selecting Overlay or Screen will have a similar or stronger effect, keep the bottom layer as Normal mode.
  2. Aggressive noise reduction tests ! Image 1 is your final image and image 2 is your 2nd posted image. Image 3 maximum noise reduction.
  3. I'd make a cabinet out of 100mm insulated board like this Initially I would make it air tight to stop any warm air entering the cabinet, add some moisture absorbing crystals and keep an eye on the mirrors/lenses, place cabinet in the coldest part of the garage...this method "should" help stop the mirrors dewing up.
  4. .
  5. I hope you don't mind but i tried a little edit in gimp.
  6. Reduced the noise a little bit for you. Reduced even more.
  7. Great detail on the galaxies when you zoom in. Well done.
  8. If you do paint/spray it yourself try to avoid a water based paint, I find water based paint doesn't like being rubbed down with emery paper and water between coats.
  9. Yes it seems so..thanks for the heads up, I found the general area in stellarium and when I clicked on the cluster it said "VdB reflection nebula". I'm not that familiar with the night sky. I had another attempt processing the image and reduced the noise but lost a little starlight.
  10. 7 photos taken with an iphone 4s then manually stacked in Gimp. Using VSCO camera app and remote shutter cable, quite happy with the extra lens or telescope used. ...not sure if called the nebula correctly, looks like a star cluster to me
  11. You may find some info under the "Video Astronomy" section, I found this thread which mentions a 10s exposure but reportedly a bit buggy.
  12. I had errors with .net fixed by installing both 32+64 bit versions. Do so at your own risk.GL
  13. Quite easy but I imagine my technique is quite severe and removes alot of information from the image...something I forgot to do while playing around was select transparency levels . Opened your image in GIMP 1 Duplicate layer 2 Set the top layer to either Screen/Multiply/Overlay/Grain merge or Dodge "Mode" (I just cycle through those modes to see which works best). 3 Then if I remember I should adjust the transparency of the top layer to reduce the effect if it removes too much info as in the 1st image. 4 Merge visible layers and save. Top layer mode set to "Grain merge" and the top layer transparency set at 75% this time.
  14. Well done, I'm no imager but I played around with your image in GIMP...hope you don't mind. Top layer set to "Grain Merge". (should have used the transparency slider to reduce the effect). Top layer set to "Multiply".
