  1. Is this bad collimation?

    Hi Rich, With the GPCAM I zoom to about 200x in Sharpcap and try to get the star I'm focusing on as small as possible. This usually works pretty well as I do tend to spend time on it. Now I've got a sturdier mount I'm going to be using fwhm.
  2. I've used ICE for lunar mosiacs before, it's pretty good.
  3. Amazing! Would love to see the full size image one day.
  4. Last attempt for now. I've deviced to use the output file of DSS with adjustments embedded as it seems to colour correct quite well. I just saved as a 32 bit integer TIFF and then made some more adjustments in gimp. It would be great if I could get DSS to do auto colour balance without it also stretching the data: Looking at it I may have made the background a little to dark but I didn't clip the black point. I am wondering why there isn't more colour in the stars. I'm guessing I must have over exposed.
  5. Well I've spent the afternoon on it, and I think this is a nice improvement. Quite happy with this:
  6. Don't worry I make sure I use raw! I've just tried stacking in Astroart(demo) and the red CA in the stars seems to have disappeared. I'll keep at it. I'll try setting the white balance to auto on my next attempt. Thanks for the comments
  7. Thanks Mike. I can see what you're saying about the noise but this version is a bit to stark for me. I was using ISO 800, but it was a warm night and the sensor was between 23 and 26 degrees. Maybe thats why the noise is so high. I'm going to give this another go. I do tend to rush out an image, I'm going to have to learn to take my time and be patient.
  8. Thanks Tommo. Yes thats definitely better. It was was to orangy on my screen too. I'm not very confident with messing with colour balance and I set DSS to align the colours automatically. I had my 500D WB set to daylight, but I thought that was OK. Maybe its the lens.
  9. Thanks Martin, I have cropped this image. The corners were showing distortions even at F5.6, and also I didn't perform a meridian flip and the galaxy went off center, probably due to a sudden weight imbalance. I'm not sure sure if the severe chromatic aberation is due to the lens or maybe I over exposed? It's very noticable in the larger resolution picture and gives the whole image a reddish look. All that being said I'm still happy with it and its the best image I've got yet. Wouldn't mind a bit of constructive criticism though lol.
  10. Took this last night, my first night out in a while. It's my first time using a DSLR and I made a few schoolboy errors, like not covering the viewfinder and and not adjusting weights after going past the meridian. Taken with a Canon 500D with a Carl Zeiss Jena 2.8 135mm at F5.6 on a HEQ5. 50 x 180s Unguided 12x darks 20 x Flats 20 x Bias Stacked in DeepSkyStacker and processed in GIMP 2.9.5. Any criticism welcome.
  11. BYEOS Ascom dithering

    Got the answer from BYEOS forum, I'll leave it here for future reference: With the Premium version of BYE the top of the BYE main window contains controls for controlling ASCOM devices (telescope, focuser, filter wheel). Select the telescope, click on the gear button to launch the ASCOM Telescope Chooser to allow you to choose the telescope driver. Change the Properties as needed and click OK. Then click on the telescope checkmark button to connect BYE to your telescope. Then ASCOM dithering should work.
  12. Hi, I'm trying to dither via ascom using Backyard EOS but I'm getting the message 'dithering cancelled - mount not found'. I'm running a HEQ5 via EQMOD with CDC and tracking and gotos are working fine. I've selected ascom for my dithering in BYEOS. any help would be appreciated.
  13. Is this bad collimation?

    I think it was a bit damp but I was using a dew shield and that seemed to be doing it's job. It could be possible that the sensor could have fogged up. The 130PDS is brand new and spotless. I'm giving it another go tonight so we'll see how it goes. It seems that collimation isn't the problem so thanks for the replies, hopefully tonight seeing will be better.
  14. Is this bad collimation?

    Fair enough, the stars still do not seem right though. Could it be tracking? Or could it be the seeing conditions?
  15. Hi, I had my first light with 130PDS and HEQ5 about two months ago: It's not great, and my processing leaves alot to be desired, but my main worry is the halos around the stars. I thought I wasn't meant to be getting that in a reflector. I don't think it's coma as I don't get coma using this cam (Atair GPCAM) with a 130p. Could it be due to seeing conditions or collimation? The halos are in single subs so I don't think its the stacking.
