  1. Thank you Iapa, the camera is a OSC and I took 29, 300 second exposures, 12 darks and bias and 15 flats. I used a CCD cls filter. Moving away from Maxim DL, I stacked using a demo of Astroart and the background is now a lot blacker with the colours being as one would expect.
  2. Dear all, I imaged the cocoon nebula last night using my Atik 320e camera and a CLS filter. I used maxim DL to convert to colour, Align and stack. However, the resulting colour of the final stacked image is whey too blue. I have tried different bayer matrix within maxim DL and this is the best colour I can get. Please see picture below. Perhaps I am doing something wrong. I have attached a link to the light and calibration frames, if anyone wants to have a play. Any advice would be appreciated https://drive.google.com/drive/folders/0B-Afq_Dv8HerbUY4clBTd19TMXc?usp=sharing Group1-16 bit.tiff
  3. Thanks for the replies. The image is not a mosaic. The DSO is in the center of both images. However, with the second session, the camera was rotated 76 degrees compared to the first imaging session. Here is the original stack. I'll try and follow Daniels and Sub Warfs suggestions.
  4. HI all, I took 79 light subs of the Hart Nbula over two sessions. However, DSS was unable to stack both sessions in one go, I had to stack each session separately and then stack the two DSS images. The result can be seen below. How can I get rid of the two edges on the right and left of the image. I use Photoshop for my image processing. Any help would be greatly appreciated. Cheers
  5. I have had another go, again trying to keep the noise down to an acceptable level. I think it's an improvement over my first attempt.
  6. Thank you Wimvberlo, again, noise appears to be the issue. I had planned to take more subs, but sadly, clouds are forecast for the foreseeable future. Yes, I noticed that too, stars are elongated on the LHS. Will need to check my optical train and collimate.
  7. Many thanks Ouroboros, yes, indeed it is a trade off between noise and the level of information visible. I had the same problem when I processed the image.
  8. Greetings all, A beautiful clear sky last night and imaging the Bubble Nebula was my plan, 25 x 5 min stubs and calibration frames using a Skywatcher 200p with an Atik 320e Camera. I absolutely adore the bubble shape and i have enclosed the processed picture. Unfortunately, the bubble shape doesn't really stand out from the background as much as I would like. Processing is not one of my strong points and I have tried my best. Data was stacked in DSS and processed in PS CS6 If any of you gentlemen have some time, I would appreciate if you can have a go and see you can bring out the lovely bubble shape.. I have enclosed the link to the calibration frames https://drive.google.com/drive/folders/0B-Afq_Dv8HerWDJXbTNOVGRJdUU?usp=sharing Many Thanks Surinder
  9. Dear all, I am planning to image a DSO, which for the first hour and a half of darkness is behind a tree. Could I use this spare time to take my darks, bias, flats etc.? Cheers
  10. Thanks William. I'll double check the cooling next time. I did notice the Amp Glow and assumed there was some light entering the image tray from the various lit LED's. The Atik 320e does not have managed cooling. It is either on or off, and so within the Atik artemis capture software, the CCD temperature is set as 'Unknown'. If the cooling is faulty, I wonder if Atik do repairs aswell? I'll also double check the collimation aswell. Many Thanks Surinder
  11. Thank you very much Stuart, and I appreciate your time and efforts. I have downloaded PI on trial. It looks a lot different from Maxim DL. Also, I definitely need to dither when guiding. As you say, this may improve the image. cheers Surinder
  12. Hi TW, Hmm very strange. I assume you used DSS for stacking? Did you change the Bayer pattern to RGGB? I didn't have any issues stacking. Not suit why the images didn't stack.
  13. Many thanks Stuart and almcl. I will download and trial Pixinsight as it is fully functional during the trial period. I use PS for processing, so will try PI for stacking and see if it makes a difference. If anyone would like to have a go themselves, the light and calibration frames are here. It would be interested if the issue is the stacking software or the source data. https://drive.google.com/open?id=0B-Afq_Dv8Hercm1NdnFXVGxhZ1k Once again, thanks for the help and advice.
