  1. Seems it is faulty, it's missing a part on the bottom of the sensor so it's going back!
  2. Hi, I bought a spyder3pro from fleabay that arrived today. I activated the version 3 software and ran through monitor calibration.... my monitor is pretty good to be fair but when measuring with spider it showed the green as really, really low. Running through the auto calibration it then produced a horrible colour profile with green cast as well. I've never used monitor calibration hardware or software before, it looks like this might be a faulty unit I've bought 2nd hand but anybody able to confirm/assist? Im not sure what else I can try.....
  3. Brilliant - thanks for doing that and also providing the details of how you did it! Will go give it a try myself. Cheers
  4. See the image, my monitor seems to show grey images as brown, the right hand side is my laptop where to me the colour looks more grey. I've played about with the windows settings but cannot get it right. Anybody know anything I can try?
  5. Hi, I got about 7 hrs of L and an hour each of R,G,B as well as an hour of Ha but for the life of my I cant get it to add the Ha properly to the galaxy! I get horrible colour casts, also my Ha seems noisy when stretched, tried to do a low stretch and just keep what I want by making the background black but that also does not work! Can anybody assist? I've attached the XISF files from Pixinsight, would appreciate a little help/advice HA.xisf M31_LRGB.xisf
  6. No – I dont think it looks like a Pelican either! Anyway, this was taken over 2 nights on the 27/28th August, totally around 7.5 hrs of narrowband 2 min (Ha/Oiii) and 5 min (Sii) data. Its taken a while to process, the data is good but I was not happy with the background so I cropped it in a bit. The scope was my William Optics ZS73 with an 0.8 reducer bringing it down to a pretty fast F4.7 (Its natively F5.9). Anyway, pretty happy with this, still getting used to narrow band processing as the colours are very subjective. This is in the Hubble Palette and has Sii mapped to Red, Ha to Green and Oiii to Blue.
  7. Cool, pretty much what I thought - I think I need to go a mm or so further in but I like the idea of taking it out further to see what shapes they look like when its knowingly too far out
  8. I think its now down to spacing - but I cant figure if its too far out or too close!
  9. I emailed William Optics about this and they send an image of the focuser and said to tighten the screws. When I checked, one of them did need tightened, only about 3/4 of a turn, the others were tight but I gave them a little 16th of a turn to tighten them and its now looking a lot better
  10. I'm really wondering if I need the focuser lock screw back in, I removed it when attaching the motor focuser and forgot to put it back in. To refit would mean removing the motor again as the bracket goes under the focuser and won't let me get the screw in. That might be today's job! One of the advantages of work from home.....
  11. And just to check, the finder screws are the ones that are not countersunk in the image above? The ones on the side
  12. Cheers, will order some and see how they go, could you feel the slop in the focuser? Mine to be honest feels rock solid!
  13. I think I have a bit of focuser slop in my WO ZS73 - I get elongated stars in a couple of corners that move when I rotate the camera, so I believe this indicates is not the camera but the scope/focuser? Im wondering if its possible to tighten the focuser on the ZS73 and if so what screws? I have an electronic focuser connoted to the scope currently, and had to remove the focus lock screw for this to fit, I also cant feel any slop in the focuser but I assume that doesn't mean there is none as it only needs to be a fraction of a mm anyway
  14. I watched that vid and it looks good, how does he build it though? I saw the video where he makes it but what's the 2" tube that he uses to hold the camera? I wonder if any Astro manufacturers would consider selling one of these jigs?
  15. Ah! How obvious! I get it now and yes it works a treat.... Thanks
  16. First time using Autostakket and Im a little confused! I load my image in, click analyse, get it to create alignment points but when I want to save, I want to stack the best 50% (Whats a reasonable % to stack? This is 2000 frames source file) - what are the 4 options for? Also, any tips on using wavelets in Registax? Never really done any planet imaging for years! I knocked up an IR filter with some film somebody gave me years ago and had a we go last night with my 8" SCT and ASI120mini Jupiter2.tif Saturn.tif
  17. Thanks Alan - I strongly suspect I will adjust the flattener till I get to a point where I can live with it - Im not a pixel peeper! I also realise that this is not the worlds most expensive scope or camera and as such Im realistic in what I can achieve... Also, I think its the camera that has the tilt as it did follow it from top right to bottom left when I rotated the cam. Thanks for all your assistance with this, it has been really helpful
  18. Bottom left still looks the worst - silly question, but do I determine what corner of the camera is bottom left to adjust tilt? I do have a tilt adjuster but Im not sure I can use it, due to the adjustment screws hitting off the filter wheel and knocking it out of tilt!
  19. OK folks - how does this look? I think I might need to add a little more extension but t my eye it looks better - the tilt seems a bit improved as well, or will that become evident again once I add more space/extension?
  20. Spot on BTW, 3mm, so I reduced the extension tube by 3mm down to 5.3
  21. Thanks @symmetal, will go check things again before it gets dark and see how it goes tonight
  22. So spacing should be 9.5 taking into account filter and ccd cover
  23. Ignore the spacing in the last pic, that was last nights spacing!
