  1. An excellent Venus, as always by you Kostas.
  2. Yes, I’m viewing on my iPhone. Currently traveling, so don’t have a large screen. EDIT: Just looked on iPad and see that they the same - as you say the iPhone scaled them to screen size.
  3. Did you drizzle, or resize it, as the ‘new’ version looks larger.
  4. So it normalises to black 🤯. Is that for all %s? I won't be upgrading yet then....
  5. That's so true Pete, it's changed hugely since I took early retirement 11 years ago and even in the past 2-3 years the advances in camera technology has been phenominal.
  6. If you have several SERs from the same session, then it is definitely worth taking a look at WinJupos to derotate and stack the TIFFs you are creating from each SER. I know that just more stuff to learn, but it can significantly increase the SNR of the final stack. Based on the image you posted above, I think it will respond well to stacking more data. If Maybe even try 20%, 25% or 30% of the single SER to see if it will take a bit more. It's always a bit of a balancing act..... Good luck.
  7. It's difficult to be certain examining that small scale image on my laptop, but it looks as if the additional sharpening has brought out some noise. It has that slightly speckled look from sharpening the high frequency detail/noise.
  8. Thanks for the feedback Alex, so what happens with normalisation?
  9. That's turned out well for your 2nd attempt. the main features are well seen and some detail coming through.
  10. Thanks Kostas, yes, I'm very surprised how well they scrubbed up. I was pretty close to deleting the lot, but stuck with it and well.....🤔
  11. I'd heard that there was a new version coming, so I'll be interrsted to know what you think about it.
  12. Thanks to Kostas (@Kon), who notified me of an upcoming interesting moon alignment around Jupiter yesterday evening, mainly that 3 of the galilean moons would be stacked vertically fairly close to the right of Jupiter's limb. I headed out to see it, but unfortnately had lots of cloud here so missed the event. Nevertheless having opened up the observatory, I decided to try imaging the remnants, both widefield to get all 4 gallliean moons in view (Ganymede way off to the left) and later just with Europa, Io and Callisto. The wide FOV image was using the full sensor as seen through the C14, so I only just squeezed everything in. I derotated and stacked the best 1000 frames from 5x1m SERS for the wide FOV and best 1000 frames from 7x1m SERS for the closing in view. The seeing was awful and clouds continued to plague me, hence the very soft images, eventually shutting me down completely. Looking at the 4 moons alignment on screen whilst capturing the widefield image, I imagined that Cupid had fired an arrow through Jove - ok I've had too many late nights recently....!!🤪
  13. Nice capture with good details showing. It looks a little blue/magenta on my screen, so maybe check the colour balance.
  14. Thanks Pete, I lost touch with the hobby for the best part of 30 years, due to family and work comitments, but since I retired in in 2012, work at least has been one thing I haven't had to juggle in my life...
  15. That's excellent Kostas, thanks for the heads up about the alignment, but cloud cover here meant that I missed it. I'll put up what I captured a bit later in the evening, but as we discussed the seeing here was awful as well as continuous clouds passing through.
  16. Nice images, with lots of details.
  17. That looks good Paul, you pulled some excellent details considering the stormy conditions. The GRS and it's wake are nicey seen.
  18. That's a very nice start Ian. As Stuart says, Autostakkert is better for grading & stacking than Registax, though I still use Registax for colour balance and initial wavelets. Saturn is also still a challenging target from the UK, being so low down and you're a tad further north than me, so it will be even lower for you. Also it is now well past it's opposion so receding from Earth, getting smaller all the time, so much so that I've stopped imaging it. Jupiter is a much more accesible target and riding pretty high this year, even better next year, so hopefully you can get your scope pointed that was soon.
  19. Very nice images and details. Interesting to see the different colours coming from different capture software. I've not used SharpCap for planetary capture, so wondering how the channel histogram settings between FireCapture and Sharpcap compare. I use FireCature with a fairly high histogram of 85% and like @Kon I also use auto colour balance in Registax on my images, though the change is usually very subtle.
  20. Nicely done Andy, the main features are well seen. It looks like you had better seeing for the set that comprise the 2nd annimation after the GRS has transited Jupiter's meridian.
