  1. On off behaviour of ASI178MM

    Yes, playing with all the settings, and it eventually worked with default USB traffic settings, and then didn't work with the same ones 30 mins later. Will ask vendor.
  2. On off behaviour of ASI178MM

    Hi Vlaiv, no disconnect noise, camera still connected in SharpCap, PHD2, SGP (whichever program I test with), just no frames. In FireCapture it says "Capture Failed". Think I will drop FLO a note on Monday and see what they say.
  3. First light, ASI178MM/Lunt 50

    Surprised you have the time Ian with all your projects!! Blizzard dodging does sound rather ferocious. Thanks for all the positive feedback, looking forward to more of this...
  4. First light, ASI178MM/Lunt 50

    First light with my new ASI178MM with my single stacked Lunt 50. Full disk in a single frame. Lots of problems with the camera, which is another story and a LOT of learning ahead of me, but here is effort #1 of hopefully many improving ones! Isn't solar imaging so much more civilized than night time astrophotography
  5. I recently acquired an ASI 178MM (non cooled) and seem to have a bit of a problem. I have managed to get it connected, but often, it will simply not download frames. It just sits there. I have an ASI1600Cool and that works first time, every time, but this 178MM is far more precocious. Just as I am about to pack it up and send back, it comes to life and behaves perfectly normally with fast framerates etc . I have swapped USB3 cables and same result, reinstalled all the drivers, same result. I think I just want confirmation that I am not missing something daft and that I should send it back for appraisal by a professional!
  6. OGEM open source mount

    I do so hope this turns out to be a winner.
  7. Trying to understand LRGB imaging

    You are pretty much there. If you are confident that your newt setup has no focus difference between filters, then you can always do L,L,R,G,B,L,L,R,G,B... or something along those lines and dither every cycle or something like that. That way you can be sure to have something by the end, as opposed to the soul destroying L, R, G and no Blue for 2 weeks because of the weather
  8. That camera will make a decent planetary imaging setup with your scope, but I wouldn't think too hard about doing DSOs with it. It can be utilized as a very decent guiding camera once you make the move to DSOs, but you should get a lot of joy and fun out of that camera with your Mak for planetary, lunar etc.
  9. First attempts with PixInsight

    The star core holes are usually as a result of HDRMultscaleTransform operations. A simple star mask to protect bright star cores is the solution for this one...
  10. Will this cause flexure - guiding

    There always seems to be a little play in the place where a Canon fit locks into the T-Adaptor for the DSLR. For imaging, it has the potential to move as the imaging train tracks, and also move if the scope/lens gets buffeted by wind. You can get away with it most of the time though I have found. Baader do a decent T-ring which seems to be tighter than cheaper alternatives, but still the movement is there if you wiggle the lens. Using it for guiding may make it worse, but that completely depends on the various image scales of the guiding versus main imaging setups. I have added tape on both sides before, once locked in, to try and add some resistance to movement to my system when using a setup like this.
  11. Imaging with a Star Adventurer

    Its like one of these : http://www.rothervalleyoptics.co.uk/baader-v-dovetail-clamp-70mm.html
  12. Cone Error and Guiding

    If the light beams enter the scopes perfectly parallel to the pointing of the scopes, then I would have thought that it makes no difference if that system is one single scope, or multiple smaller scopes all perfectly parallel with one another. Light from stars arrives in parallel beams, so unless we are talking about extreme widefield, where projection of the curvature of the celestial sphere comes into play, I would have thought they are completely interchangeable.
  13. QHY10 with Purple Frame...

    The holes in the stars are processing artifacts from the stacking. You need to have a play about with the stacking/processing parameters to avoid getting those. Welcome to the wonderful world of data processing...
  14. I used the one from ModernAstronomy: http://www.modernastronomy.com/shop/accessories/polemaster-adapter-for-star-adventurer/
  15. Imaging with a Star Adventurer

    I have a polemaster, so PA is pretty good after doing that. Also, with short exposures, it doesn't really matter if it drifts slowly, natural dither,albeit during subs as well
