  1. Thanks for that - I will give that bolt a tweak then... Much appreciated
  2. Hi. I have the Skywatcher Equinox 80, which is a stunning scope. However, when loaded with a DSLR and Field Flatenner, the focus tube does not lock in place with the inadequate thumbscrew. This causes problems when imaging object near the zenith. Is anyone aware of a solution to this problem? I wondered if there was an aftermarket solution anywhere? It's the only flaw in the scope that I have.
  3. JIM, thanks. What did you do in Elements to bring that extra out?
  4. Thanks for your comments. I agree about the blackness - that is straight out of the camera and not through processing. It seems to be the effect of the clip in filter. Without it I am surrounded by street lamps and Scunthorpe steel works, so the pollution is really bad.
  5. HAd a play for the fiurst time with a modded 450D last night. Quite leased with this but would appreciate any hints and tips. Celestron C8, unguided EQ5, Atik Clip in LP filter, 17 subs at 70 seconds each, ISO 1600. Processed in K3CCD and CS3.
  6. This is my first attempt at the Horshead and first light with a modded 450D. Interested in any hints and tips. I used an Atik clip in LP filter (we live in a bad area for light pollution) Celestron C8, unguided EQ5, 17 subs at 90 seconds, ISO 1600.
  7. Hi. I modded a 450D this week, just taking the filter out and not replacing it. Should I be using any other filters when taking pics now? Having tested it on a clear sky last night, exposure times are shorter but it is more sensitive to pollution from street lights. What white balance setting shouldn't I use? I noticed I can get rid of much of the pollution by changing the white balance in the Canon software after download but can't work out the setting in the camera. Is it normal for a modded camera to be more sensitive to light pollution? I have a clip in light pollution filter that clips into my 50D ok, but not the 450D, it drops out! Any advice much appreciated.
  8. This is my first attempt at M42. Used a Celestron C8 on an EQ5 (unguided). EOS 50D (unmodded) and Atik clip filter as I live in a highly light polluted area. 10x90 exposures, ISO1250, stacked in K3CCD. Any feedback very welcome.
  9. I'm afraid I have no idea what went wrong, but I have similar problems using a similar setup (particularly with the Neximage). Will be interested to see any solutions that come your way. Also interested in the "RAW upgrade fix" that you mention, not heard of this...

    M51

    Thanks for your comments. I used DSS on both, but am having real trouble with the settings, so tried a couple of times and got two different outputs! If only I could master DSS I would be happy
  11. Thanks - glad you like it... I agree with you, must be my favourite countryside and hardly any light pollution! :-)
  12. Taken last week in Pembrokeshire. 3x 90 second exposures, some darks and flats (the clouds came so no more lights unfortunately). My first attempt at widefield image with camera mounted on the EQ5. Canon 50D and Sigma 10-20mm at 10mm, ISO 2500, 90 second exposures unguided on an EQ-5.

    M51

    A couple of images of M51 taken last week in Pembrokeshire. Celestron C8 SCT with Antares f6.3 focal reducer, Canon 50D, ISO 2500, 14 90 second exposures unguided on an EQ-5, darks and flats.
  14. Does anyone know of a good tutorial for newcomers to K3CCD? I can't work out how to process a series of images from my DSLR. I must be missing something simple!

  16. Hi. Yes this was a f10. I have the reducer, but I thought that was for widefield views, so thought I would lose detail of the galaxy if I used it. I'll give it a go, thanks for the tip! The LP Filter does turn everything blue unfortunately, and I can't work out how to get rid of that and restore the correct collours - DSS baffles me really. Want to try a different program to see what effect I get.
  17. Hi. I thook these images last night. Not the best of seeing conditions, but not bad. The first image (cigar.jpg) at 3200ISO 80 sec exposures and 3 darks... The second image (cigar1.jpg) identical except I used an Astronomik light pollution filter. I would like to know what I could do to improve these or my technique. Using the Astronomik filter cuts out some pollution, but also a lot of data it seems. Used and EOS 7D with a Celestron C8 on an EQ5 Synscan.
  18. This sounds interesting, but as a complete novice I have no idea what a FITs file is. Any advice for a layman would be helpful...
  19. That is certainly an improvement, just had a go with those settings. Thanks... The image has more detail but still comes out with no colour though, so can't fathom what I've done (this keeps happening to me in DSS, and I don't know why).
  20. Thanks for the fast reply, I'll give it a go.
  21. I have recently tried out the Astronomik clip filter in my EOS 50D. While it cuts out the light pollution, it turns everything in the image blue. I can't work out how to restore the correct colours in DSS or Photoshop. Has anyone else experience of using this filter, and how do they correct this? Cheers. Charles
  22. Thanks for this. That's a usefuil tool, I used it to reset the image but, when stacked, it wernt back to the dark result. Should I have saved somethng once I'd adjusted that slider?
  23. Hi. Yep, tried that in many different ways, and it's making it worse for some reason...
  24. Hi. I am baffled by Deep Sky Stacker. When I take images on the DSLR I can review the image on the screen and all looks well... When downloaded into lghtroom the data is there and I can see the nebula (in the latest example I was imaging Bodes) but when I then put the files into DSS and stack etc (with darks and flats) all goes dark and the nebulosity disappears (along with any colour saturation). I can't work out what I'm doing wrong - so any advice very much apreciated. Latest image taken at ISO 1000, 110 second exposures through a Celestron C8. All I have to show is black with a few stars in DSS... Very frustrating!
