  1. IC405 - HaRGB

    Thanks Martin. yes, the black is a bit clipped on that version. I've worked on it a bit more and managed to get the star colour a bit better. It really does need more data though.
  2. Flats won't change the colour balance of your image, as they are done per channel.
  3. IC405 - HaRGB

    Thanks Steve
  4. It would be worth your while getting or printing your own 18% grey card and then creating a custom white balance for the CLS filter. It takes out some of the hard work in getting the colour right.
  5. IC405 - HaRGB

    My first colour image with a mono CCD. This is 4.5 hours of Ha (9 x 1800) and an hour each of red, green and blue (12 x 300). Blended in Pixinsight.
  6. IC1396 WIP

    It seems to be Elephant season, so here's another one. Captured from the back garden last night with ED80, Avalon M-Uno, Atik 460EX with 7nm Baader Ha filter. 10 x 1800 subs. Hopefully will get some more Ha and then add some OIII later. Thanks for looking.
  7. I contacted Lakeside and they put me onto the chap who wrote the driver. I said I was interested in trying it. Lakeside have now agreed to allow it to be incorporated into the INDI build, so good news there! I've tested it and it seems to work ok. I'll be testing it fully as soon as the sky allows.
  8. Thanks Graham, I'll do that.
  9. Does anyone know if they plan to include a driver for the Lakeside Focuser? I'd love to switch over to Linux but I'd rather not shell out just to replace a device that works.
  10. Guide scope or OAG

    I've tried this. You need an extension tube, I'm pretty sure over I needed 50 mm with my QHY5-II. Edit - I use an Altair Astro 60 mm guide scope. Much better in my opinion. Lighter, less chance of flexure, better optics.
  11. Skywatcher focuser upgrade - camera question

    I upgraded my ED80 with a Moonlite focuser and a Lakeside motor. It's a massive improvement on the stock focuser.
  12. CCD reality check

    I was just looking at the same graphs. The ASI1600 graph is relative - that camera has a peak QE of around 60% (according to ZWOs manual), so at 656 nm, you have about 77% of 60%, so around 46.
  13. CCD reality check

    I can honestly say I've not yet seen a image from one of these CMOS cameras that holds up against a CCD image. Zoom in and the noise really starts to show, even on the longer integration images. I'm also curious about the lack of the need for guiding. Even with good polar alignment, surely periodic error creeps in? Fine if you've got a permanent setup and can PEC train but not so much use for those of us on tripods? Happy to be corrected if I've got the wrong end of the stick.
  14. CCD reality check

    That's ok if you have a permanent setup. I'm running off battery, so another power hungry device would be unwelcome and I wouldn't 100% trust wifi to get my files synced with the cloud.
  15. JPG is a lossy format and you'll be throwing away image quality. Try PNG instead. The files are bigger but not as big as a tif.
