  1. Guys, how do you process your stars? Mine seem to come out fuzzy??... Tried star masks but somehow it's not quite right and sharp.
  2. It's never ideal, eh?! I think, I want myself an obsy/shed where I'm permanently set up. Roll open roof (by push of a button) and off you go...
  3. Had visitors over and couldn't go. Funny this hobby - makes me wanna hate friends and family that keep me from going into the garden...
  4. Hi guys, I've always struggled with keeping my stars nice and neat. But that wasn't a major issue with a large DSLR sensor before. With the Atik314L+ now I find myself struggling to my dismay. I've separated the nebula in Ha from the stars in Strata and am now left with a stars only layer that I want to stretch. Stretching it however blows the stars up and gives me strange fuzzy unround "halos" around my stars. I've tried reveal all layer masks to prevent the cores from burning out, but it's the fuzzy bright halos I can't control. And as soon as I unsharp mask this layer I get weird black dots inside the outer part of the brighter stars. Can you point me in the right direction? Will upload an image later when I'm home...
  5. I use AstroTortilla too, but slight differences b/o movement or camera rotation already make a difference. In particular if you're stacking like 100 images...
  6. After a long abscence I've finally managed to start with NB imaging... Moon was up - but with Ha you get quite a good result as opposed to my previous Canon attempts... lol Anyway, judge kindly, I somehow need to figure out how to prevent stars from bloating. As well - On the stars right hand side I can see an indentation which I think stems from the focuser tube jutting forward into the scope tube. Anyway - now I'm waiting for clear skies to add OIII and SII. Oh, and I've realised that by imaging several nights and adding more images you de facto are making your final image smaller, because you will never be 100% spot on with your subsequent images, hence cutting off at the edges in stacking. So I guess - looooong exposures is the way forward to increase image size... sigh... On the bright side (even though this image below is 500s exposures) I did manage to do one night of 1000s for the first time with SII. With the moon nearly full, you couldn't really see anything unfortunately. And, now all these images are stuck on a USB stick that suddenly decided to pack it in... uff
  7. For the initial question - I use a finderguider with a QHY5 on my 130 PDS which works just fine. I've imaged upto 1200s. Recently though, the finderscope shoe had come lose and caused all sorts of weird guiding. Weight wise the finderscope is better. But it depends on your mount.
  8. I know that Uranium has actually sawn of the ridge of the skywatcher coma corrector in order to put the whole camera setup further inside the focuser and thus reduce the length the focuser sticks into the actual tube. Would there be another coma corrector fitting the 130 pds where you wouldn't need to do that? Anyone has one?
  9. Ooh, just recently had an issure with AT - I've tried using 2x2 binning and it really didn't work - so I went back to 1x1 binning and it found me again. What a drag sometimes...
  10. I'd say, forget about narrow band on DSLR's. Rather start saving for a dedicated CCD...
  11. In comparison - if I don't choose the blend option in startrails, it really looks like morse code ... lol...
  12. oh - noise reduction in the qhy5? I have to look for that - I really have never used that old second hand camera for imaging I must say - only for PHP - and there it does what it should.
  13. my image wasn't magnified - it's really just the Qhy5 on a 9x50 finderscope... (fl = 180mm - probably less)
  14. Hi guys, this was just for fun - my guiding setup gave up on me, so I had the finderguider disassembled - exchanged and tightened screws etc. While looking out the window I saw a few sparkling stars and remembered that I always wanted to see how to do startrails. So I opened the window, leaned the finder guider out of it and hooked my guidecam up to the comp and shot 100x 30s exposures. what I'm a bit bewildered about is, that I have gaps inbetween the trails even though I had left no pauses between the exposures. I suppose it's the time it takes to load the FITS files to the comp and the quite large magnification b/o the rather small chip. Well anyway. Here's my attempt: (don't laugh too hard...)
