  1. You can also get mini table top Dobsonians. Carole
  2. An ETX without the tripod sits on a table quite nicely. Carole
  3. I don't know when l will get a chance for more data, l have to go to a dark site with low horizon. Obviously that would be desirable when possible. Carole
  4. Thanks Ray. Carole
  5. Following Rudeviewer's beautiful image of M20 it inspired me to go back and re-look at my processing of this target which I thought looked very washed out in comparison.
  6. Really beautiful, it has inspired me to go back and re-do the processing on my own M20. Carole
  7. Whilst it is true that you won't see colour with the naked eye, surely the colour produced by a non colour enhanced DSLR has to be a true colour. Admittedly this is done in long exposure which the eye cannot do. I think the most exciting objects to a beginner are Saturn and Jupiter, followed by globular clusters. Carole
  8. I have CS3 and can use gradient exterminator on that. Maybe there is a different or earlier version download for CS3. try speaking to the Author Russell Croman he is very helpful. Definitely looks like lack of flats to me, but can't comment on the green colour. Carole
  9. I am puzzled why film is being used for flats. I just use a piece of cardboard made into a sort of lens cap so the collar fits round the scope with typing paper over the aperture end. This is for day time flats of course, but when I used to use a EL panel, I still used typing paper, never film, so just wondering about the logic of this. BTW I think my cardboard and typing paper and sticky tape is even more Blue Peter than the nicely carpentered one above. Carole
  10. I would go with a piece of space junk, like the 2nd stage rocket suggestion.
  11. Absolutely agree with Olly, probably the best purchase I have made. I have two CCD cameras and a DSLR and 4 telescopes. I can combine the data of any combination I like. One image I took years ago with a DSLR was the Horsehead Nebula. When I tried to add Ha to it, whilst I found I could register in other programmes (can't remember what I used now and they didn't always work), when I overlaid the Ha the stars matched at one end of the image but did not at the other end. Presume this could be the effect of different scopes and flatteners. Took it into Registar and Bingo. Registar will even stretch the images to make the stars line up perfectly. Could not and would not be without it. Carole
  12. Good tip, as I hear Lexel is no longer available and even Skypod were worrying about it. Carole
  13. Well maybe fast optics might make a difference, but I could never see nebulosity with my DSLR, even after doing a long exposure I might only see a faint hint of it. Only processing would bring it out. I coped getting focus by marking the drawtube so I knew where the point of focus roughly was each time, but doing it from scratch I used to use the Moon to get rough focus. Once I was close to focus I could actually see a star on live view and then could complete focusing. Well that was my experience. Carole
