  1. Yeah its a tough one with Luminance. I noticed that in some of my photos adding a luminance channel doesn't make that much of a difference if any. If you are binning 1x1 for lum and 2x2 for RGB then Lum should certainly reduce the background noise. Ray
  2. Stunning starfield buddy. Ray
  3. After four nights of hitting brick walls, posting two threads on PI's forum and reading and watching a ton of tutorials I posted this earlier on FB. Worth posting here as well - I'm trying to reduce large stars (not low focal length stars which are medium to small), the PI function "morphological transformation" (MT) appears only to work with small to medium sized stars (which surprises me, why would they leave "large" stars out of a "star reduction" algorithm, Spock would find that highly illogical, as I do). I have been using a star mask from day dot (even using MT on the star mask to ensure the protection wasn't too extreme). I've posted twice on the PI forums asking them about this with no solution (from the experts). I've also watched and read a ton of tutorials. This really surprises me that a dedicated astro processing program like PI cannot do this. But not only, not do this, but not do it quickly and simply> Select stars sizes with a min and max slider>size adjustment with another slider> fuzziness or smoothing with another slider> apply. Done. Every tutorial I've read has so many steps and hoops to jump through to perform such simple reduction on medium to small sized stars, that other software can do in literally 20 seconds, with no training, at a cost of $20 (PS pluggins). Seriously, what am I missing? I bought Warren Kellers instruction book on PI, and I have been diligently working through it, and at the part where star reduction came into it, that is where I hit a brick wall. So I should be fair and mention that I haven't finished reading it, but the fact that two posts on the PI forums draw blanks from the PI experts is a very big worry. My comments above are well documented from other user threads online elsewhere all the way back to 2010, so I'll be perplexed if something hasn't been implemented since then. I could harp on about other stuff in PI but I want to be completely fair and give it a proper effort, I've had it for about 12 weeks, I've spent dozens of hours learning it, yet still struggling to reduce stars that I can do in other software in 20 seconds with no training for $20, but I'll hold my judgement until I've finished Warren's book. Thanks again to everyone that has tried to assist. I shoot at 4000mm FL and get pretty big stars. For anyone finding this thread on Google, I currently use Noel Carboni's actions and also another pluggin called Star Shrink. Until I find something better, those are what I'm using. Hopefully PI comes out with something. I'll respond here again if I work out how to do it in PI, but a quick warning, its been four nights of hitting brick walls with PI. Regards Ray
  4. I agree, summer went straight into winter, no transition. 40 degrees one day, blowing a gale the next. Good to hear your eyes are doing well. Were you expecting any particular feedback / condition about them? Ray
  5. Hmm. If your current computer isn't locking up, go the OAG. That said, have you seen an On Axis Guider (ONAG)? Ray
  6. You must be loving that mate. Good feeling. Now all we need are some clear skies. Ray
  7. Very nice Dave. With so many late nights in the observatory (when its clear), i miss these beautiful sunrises (except on the really late nights in the observatory when I'm still up). Ray
  8. Wow mate, so am I right in thinking you have solved everything? You must be loving slewing that mount around? Its a good feeling when it works. Astrophotography forces us to become software and electrical engineers among many other trades. Ray
  9. Well I am very impressed so far with what I am learning. Of this 389 page manual I am up to 130. However I've trawled over those pages twice now and performed every function so far as to make sure I absorb this well. I'm happy to say, that average looking data or average looking master subs become extremely vivid and detailed when the software is applied correctly. PixInsight is not for the faint hearted though. You really have to put in the time and effort to get the rewards. I can't wait to absorb the rest of this manual at this stage. Ray
  10. Hi Dave, Have you considered a scope trolley for that rig? Seeing as you have a paved floor it would be very handy. Ray P.S Nice looking kit by the way. Murphy's Law it will be raining all week now.
  11. IMO, PI requires a course book and Warren's certainly does that. I watched tons of video tuts and got somewhere with PI, but the book really puts things in perspective. Can't wait to get through it (and absorb it, which will be the harder part). Ray
  12. I'm trawling through PI last few weeks. I've got heaps of new data but I'm refusing, protesting, standing my ground, and not going to process anything until I've wrapped my head around a 389 page instruction manual for PI. Everytime I read another chapter I'm wanting to go back and reprocess, so I'm being patient and doing the PI learning curve first. I've been using Cosmetic Correction tonight and whilst it is clever at removing hot pixels (and even cold pixels), I'm noticing that it only removes hots specs of a certain size. It can be used for pixel sized noise removal as well which is handy. I'm yet to use the Master Dark Frame option with Cosmetic Correction. The defect map however does enable a user to select specific defects for removal. If you had a lot of noise it could take a while however gives you much more control over what happens in the resulting image. Ray
  13. Well done Prof, as always. Ray
  14. Agreed, impressive for a test shot. Glad that down time was only for a few days. Ray
  15. Interesting result Eric. What tools did you run it through? Ray P.S I don't think there is any compression on the upload, I'll check.
