  1. This is the result of my main imaging session last night, early evening was spent cloud dodging but come 10:30 p.m. the cloud went and the night sky was amazing with good seeing. Here's the details: DSLR Prime focus on C8-N; 22 X 5min subs, ISO800; Guided with QHY5 on ED80 using PHD; Processing PixInsight DBE, PS CS3. cheers Keith
  2. I actually took this right at the end of last night's session, its just a single 5 min exposure, but anyone that was lucky enough to get clear skies last night was in for a treat - lovely clear atmosphere - well at least over my bit of somerset . Here's the detail : Prime focus DSLR on C8-N, guided with QHY5 & PHD on ED80. Bit of fettling with Pixinsight DBE, PS CS3. cheers Keith
  3. The amount of detail is simply stunning This is already superb, colour will be the cherry on the top Keith
  4. Apart from all the excellent advice already given from your kit list I assume you're using the SW 150 Newtonian to image with? If so you should get diffraction spikes from the support vanes for the secondary mirror when imaging a bright star. You know when you've achieved good focus when these spikes are viewed as sharp distinct points radiating out from the stars centre. I usually pick a bright star to achieve focus through the DSLR viewfinder (the brighter the more prominent the diffraction spikes), take a test shot of 60 seconds or a bit less and then check with max zoom on the cameras lcd screen. best of luck Keith
  5. You're right about the CLS TJ, sometimes I think its more trouble than its worth. I may have another stab at this one but use the C8-N instead for better resolution, plus it will be alot faster at F5 rather than the ED80's F7.5 Actually I think the image looks alot better when viewed from my SGL album rather than this attachment; I guess it loses some quality in the compression? cheers Keith
  6. Taken last night, but unfortunately not as long as I wanted (PHD lost the guide star for some reason?!!) The two largest fuzzies are NGC4889 & 4874, but there's simply loads of others in shot in this group. Details: Prime focus DSLR on ED80; 16 X 300s subs; ISO800; CLS clip filter; guided with a QHY5 using PHD on C8-N. cheers Keith
  7. Thanks for the comments If my luck holds out with the weather tonight I'm thinking of doing a whole moon mosaic, probably six panes will do it un-barlowed -fingers crossed;) cheers Keith
  8. Nice capture TJ - the other fuzzies I can make out so far from top down are ... IC3546, IC3571, NGC4562, IC3533. There's probably more in there but it's just too sunny here looking at it on my work screen. cheers Keith
  9. Hi, For the image on this thread I think it was captured using 640X480 sub framing in QGVideo, just to make the AVI size manageable (1000 frame AVI), then I resized the final image just before saving it in Registax. For the other two images I've posted - these were at full chip resolution, but I limited the AVI to just 100 frames because of the file size. If disk space is not an issue I'd capture at full chip resolution, personally. Keith
  10. I've be using QGVideo-Beta for these shots. The wide shot was with an Exposure of 4 Ms and Gain of 0 %. For the barlowed closeup Exp = 10 Ms and Gain = 0 - 2% I think. These were both taken through my C8-N, which is a good light bucket, hence the low settings. Whilst QGVideo's functionality seems pretty good it can be a bit flaky cleanly shutting down though, guess that's why its still a Beta. Keith
  11. Thanks for all your comments guys I've posted a couple more in the meantime from last night. I think conditions were better last night as well; not so much atmospheric boil visible on screen. Subsequently, alot more frames were accepted by registax from my relatively short 100 frame avi's. cheers Keith
  12. Great shot CW, nice to see you posting again Keith
  13. Getting to like my QHY5 camera alot Two ends of the spectrum for my available scale at the moment. Both prime focus through the C8-N. Stacked & processed in Registax4 cheers Keith
  14. This is my first foray into closeup lunar imaging, trying out how good my QHY5 guide cam is at this type of shot. I must say I'm well impressed with the camera's sensitivity and the degree of fine adjustment that you can get with exposure and gain. Please be gentle with the comments, this is pretty much new ground for me, not even shure what the target is . Details: QHY5 + 2Xbarlow, prime focus on C8N, 350 frames from a 1000 frame AVI, stacked in Registax4 - that's about it. cheers Keith
  15. John's right, you can use a an unmodded web cam in PHD but the reason I moved on to using a QHY5 is that the chip size is also small on a webcam, typically 1/4 size - with a QHY5 it's 4X the size! plus alot more sensitive as already mentioned. Keith
  16. The improvement is clear to see, nice capture Sam. Just one comment though, have you thought about darkening the background a bit more? If so I'm sure it would be more dramatic and contrasty. cheers Keith
  17. Here's an idea a bit out of left field, found it on my web travels whilst looking up all things guide scopey (now the proud owner of a QHY5 today!). A canadian company look like they've stuck a QHY5 on the back of a 9X50 finder scope for use as a guider. It maybe worth trying to copy the idea? Advantage would be a very light guider with a wide field of view, plus it's likely to not cost alot if you get a second hand finder. Here's the link: http://http://www.kwtelescope.com/KWT_KWIQ.htm I may try this myself when I get my hands on another finder;) cheers Keith
