  1. Hi Freddie, it was bringing up the error message as soon as I hit the Register button, so it seems as if it was rejecting the frames from the start. However, things have moved on! I decided to see if I could narrow it down to maybe one or two frames that were causing the problem. I unchecked all, then checked all flats, darks and bias frames, then one light, hit register, and it started registering no problem. Then repeated this, adding 5 more lights, again no problem. Carried on 5 at a time, and all worked, right up to me adding all of the original frames! Ended up with a normal, stacked image, no frames rejected. So, maybe a glitch in DSS when using the check all button? Will have to see what happens next time..
  2. Hi Freddie, the images all seem exactly the same, 5184x3456 pixels. I'm stacking 37 lights,13 darks, 23 bias and 20 flats. The 'scores' for the lights on DSS range from 26 to 117, number of stars frm 8 to 20. I notice that the dX and dY columns are all NC though, not sure if this is usual. At a bit of a loss with this one....
  3. Definitely, and it says so in the image table in DSS. These are my first from my modded 600d, with an Astronomik CLS filter. Apart from looking a bit red they look pretty good.
  4. Hi Bsdgerchap, Success with lading DSS 3,3,3, using winrar. Many thanks! Pics all loaded now and look complete and the right way round. So now I hit the start register button and I'm getting the error message 'the checked pictures are not compatibles (width, height, number of colors, number of channels, only one master dark,offset and flat' whaaa ???
  5. As usual for me, easier said than done. The link downloads a rar file, but I can't open it. Any ideas how to?
  6. Thanks all. I've checked and its version 3.3.2 I'm using. It worked fine on my previous PC and camera.... I'll try the link you sent.
  7. Having been offline for a few weeks for a summer break, I fired up my new laptop and downloaded my first images from my new modded Canon 600D....and have an immediate problem with DSS. For some reason, every image (lights, flats, darks etc.) seem to have been imported as a narrow, vertical, rectangular crop of the image, about 30% of the originals. All settings seem the same as on my old computer, so I haven't a clue what's going on. Hopefully the attached printscreen will show what I mean. Anyone any thoughts? DSS printscrn.docx

  12. Thanks for all of the help and tips guys, it has given me a lot to work with.
  13. Thanks Paul, I will look into this when I get home!
  14. Thanks guys, looks promising. I'm going for a new laptop rather than an old, Gina, as it will also be the family PC and it needs to have good longevity. Anyone have any sparkling recommendations in the range of £500?
  15. Aenima, I'm far from being an expert, but from a cursory look on the web it seems a white card is good, but the grey card is spot on...
  16. I think I'll try the custom white balance method with the grey card, but should I leave the CLS filter in the camera when taking the shots of the card in sunlight? I think I'll have the CLS filter in most of the time when astroimaging.
  17. Hi all, I'm about to invest in a laptop for astroimaging (camera control and processing) but I noticed all in the high street now come with Windows 8. Will my favourite programmes (Deep Sky Stacker, Gimp, Pixinsight) all run OK? I've looked on the web and seen mixed opinions.
  18. Stuart, this seems to make a lot of sense to me. I have been doing almost exactly this after stacking in DSS, using the DSS processing stuff, and it helps a lot with my light polluted orange frames. So hopefully it will also work with my new red shifted frames (which look a lot like Amra's shown above). Guess I'll just be doing bigger red and green shifting. I do background extraction and colour calibration in PI also, so hopefully all will go back to normal colour with lots of new H alpha areas! Alex, are we getting there yet?
  19. Alex, I'm completely in the dark on this one (no pun intended), and hoping for salvation from the great and the good on here......I'm just trying to avoid too much wasted effort on my next AP session!!
  20. Alex, this is the gray card reference, from Kev above. It seems to be a fairly standard DSLR technique, it is certainly covered in my Canon 600d instruction leaflet. See this site as an example: http://www.diyphotography.net/diy-making-your-own-gray-cards
  21. So, looking at the responses, there is the suggestion to use custom white balance and the 'grey card' method, and relying on the post processing (or maybe both). I'm certainly a bit surprised at the added 'degree of difficulty' involved with a modded camera plus the CLS filter - although maybe the latter is the main culprit? I didn't pick this up from the many posts on using these items. In fact, all that most articles on the web talk about is how to use a modded camera for normal daytime photography, rather than how to get the blessed colour right on your astrophotos. A good topic for a tutorial? Or maybe there are some out there?
  22. Ooer, are you implying that processing a modded image is more of a challenge than an un modded? Yes, I am using RAW. I can't supply an image yet as I won't be putting the software on the PC for a week or two. I just didn't want to take too many more images if I'm using the wrong settings, hence the request for advice...
  23. Last night was the first try out for the brand new modified Canon 600d with an Astronomik CLS clip in filter. In my usual untutored way I snapped away at M82 using ISO 1600 120sec exposures. Whilst the amount of image detail and contrast to the background was much better than with my un modded 1000d, I was surprised at the amount of redness in the image - most of the galaxy was red, plus many stars. In addition, the flats came out vivid blue instead of the normal grey. Is this normal for a modded image set? Should I have changed the camera settings to compensate, or is it all done in post-processing? Can't post an example yet as I haven't loaded the Canon software yet....
