  1. Thanks, I might try the 30 days free first. I've been using DSS and Photoshop but I'm not always happy with my stretching in Photoshop although I've used it for years.
  2. Apart from Pixinsight, can anybody recommend good image processing software. Thanks
  3. Hi. Ollie Thanks for your comment about my eggy stars. A friend and I have been trying to get to the bottom of it for some time. Last night we connected the Atik directly to the scope, took some shots and then rotated it through 90% and took some more and the eggs moved, so It's not likely to be the optics but the comera, maybe the sensor not quite square. Kind regards David Alan -thanks for your help.
  4. OK thanks. Did you manage to open the file I sent you?
  5. Hi Adam Sorry, do you mean me or Alan. David
  6. Thanks all for the advice. I'm still trying to track down the egg shapes. We have turned the camera and filter wheel through 90 degrees and the egg shapes also turn suggesting it's not the optics so I'm a little undecided about a flattener. Love the Veil. I was out last night on the Eagle nebula and other targets, processing and coffee today.
  7. Thanks Adam.Ill get one of last nights M13 shots. I have egg shaped star but I am hoping this could be due to a slight mis-alignment in the filter/camera connections rather than the TS optics but I trying to cover all my options.
  8. I have a TS Photoline 80apo triplet and I'm thinking of getting a flattener but I have been told that because of the small sensor size the flattener wont do much. Has anyone any experience with this issue
  9. Ok , need some clear skies . thanks for you advice.
  10. What would your next step be. so far : Track eliminated via a different mount. Light path tight. Filter wheel filters checked to make sure they are seated correctly , There is one lump of glass left that may need correcting image wise or has one of its elements causing the problem But if I've missed something less expensive ?
  11. Yes it is the seperate stacks ... each of the 4 show eggs with differing directions , ruling out guiding maybe . The kit has also been on a different mount with no improvement
  12. I agree , Its a question of if a flattener is not required due to the size of the sensor then an objective issuse ??
  13. Sorry , the guide scope is a QHY mini guider with a QHY5 2 mono , the single subs exhibit the same problem , here is one of the subs Thanks
  14. It may be better to say they probably were all the time , it was that location ie unable to see polaris led to terrible tracking issues and focus related problems meant few nights with subs of any value
