  1. G'day Neil. I'm not doubting that images opened in different image editors will look different but the issue here is the stretched look of images uploaded to a dark or black background website compared to a white or very light coloured website background, in this case especially planetary images. This has caught me out many times as well. I have to re-edit images just for a few websites with the black or near black background. The only way to test this would be to take a screen shot of an image you've uploaded to a dark background website and take a screenshot of the same image uploa
  2. Someone has been busy. Excellent Kokatha man, all of them. A lot of work has gone in to all that. In regards to the brightening of the images I've also noticed this. It's the dark background of SGF, there's no stretching involved. Your image photo editor probably has a light background so test an image editor with a black background. My final edit tweak is done in an image editor that has a black background to balance it all out before uploading here. It's the same with facebook too when you go to full screen, that's a black background as well. Optical illusion and our eye's playing trick
  3. The best for the night, 440 frames. Captured in iCap, the previous image captured in SharpCap.
  4. arh ok Chris, I assumed low low in the sky like just above the horizon. I was starting to worry there. I can rest easy then
  5. I love a good animation, it brings Jupiter to life and the moon transit is a bonus. Excellent Angie.
  6. Pretty good Mick with some good bands showing with upper and lower gas polar regions. Keep at it
  7. Yes Stu and thanks, happy to finally get some better results and slightly better detail. I'm getting a good image scale with the Celestron Neximage 5 Solar System Imager but lacking more good frames. I'm tempted to get the Neximage 10. I'm now wondering if I should be doing some dark frames. Here's the bigger pic, 1.5x Drizzle with minimal editing, just some level adjustment, colour correction and light sharpening.
  8. Great captures Jake. I have to agree that the second image looks better but I'd be happy getting something like the first, good detail throughout.
  9. Rethinking it all again and taking note of the more experienced imagers here. This time I used 3x Drizzle in Autostakkert which I never use, I usually use 1.5x which seems to be a good balance and then reducing the size of my edited images as one of the final steps. Excuse me for exposing my pixels but if you stretch your head back from the screen it doesn't look too bad and I actually like the colour of these ones. I've held back on wavelets and final editing, as hard as that was. For a size and quality comparison I've also uploaded the 1.5x Drizzle image. 3x Drizzle
  10. Thanks all. I'll keep at it. Any AP folk are welcome here. I can't believe this. So when everyone up there gets it high in the sky it will be rubbish here for as many years before their return to good viewing? I don't like the sound of that. I'll have to get as many captures in as I can, while I can.
  11. @Grotemobile Thanks Steve. Jupiter this year hasn't been the best here, it's nice and high but conditions not good. Early morning conditions here get better in the burbs but Jupiter has passed and is much lower in the sky. I should at least give it another go when conditions improve even though it's lower. I haven't done that yet as I'm usually on to Saturn or trying my hand at DSO with a Sony a5000 which I've recently started. I'll just swing the scope around next time if I remember. Hope you all get better conditions soon. @Scooot Cheers Richard. I like seeing the moons too
  12. Thanks everyone. I'm still processing videos from that night and I'm about halfway through. Conditions may have improved while capturing as one of them seems better or I've over processed again.
  13. Ye Gad! That is a Long wait. So I guess I'd better make the most of it while they're around here.
  14. Good capture Pete considering the poor conditions. I've only ever captured a few transits, they're good to see.
  15. This 460 frame stacked image was from the same night as my previous Saturn post but Jupiter was captured a few hours earlier, conditions were not as good but some reasonable detail came through. The GRS starting to show with the smaller Oval BA further around to the left. Captured with the ZWO ASI224MC with a Celestron UV/IR Cutoff filter in Sharpcap and the Celestron Nexstar 8i SCT. PIPP used to get the better frames, Autostakkert to stack the best frames, wavelets in Registax and finished in PaintDotNet.
  16. Thanks everyone. Just out of curiosity, when will you get Jupiter and Saturn in the Northern Hemisphere?
  17. Saturn from last night. A 6 minute video was taken around 4am with the ZWO ASI224MC in SharpCap and Celestron Nexstar 8i SCT with focal extension tubes. PIPP used to get the best 3000 frames and arrange in quality order, stacked 600 of the best frames in Autostakkert with 1.5x Drizzle, waveletts in Registax and final edit in PaintDotNet. To reveal the moons which were not visible I bumped up levels to lighten the background, then magic wand each moon, cut them out and paste each one in to a copy of the original image. I think I have 4 of Saturn's moons which is a first for me.
  18. From the album: Celestron Nexstar 8i

    Celestron Nexstar 8i SCT with focal extension tubes, ZWO ASI224MC with Celestron UV/IR cutoff filter, 750 frames.
  19. I've only just got in to DSO photography recently with this being my second attempt at the Carina neb on the 24th March. I didn't need to do much with this at all in the final stacked image apart from some level adjustment and slight colour correction. I'm very pleased with this even with it's faults. Taken with the Sony a5000 and C8i SCT. 4 x 15 seconds, 9 x 8 seconds, ISO 6400. Each of the 13 light frames has a dark frame added from the camera. Aligned and stacked in DeepSkyStacker, final edit in PaintDotNet. I wasn't sure on the colour so I just guestimated. I did a quick search for imag
  20. Nice image Adam. I do like seeing the moons with Jupiter, well done.
  21. Jupiter just after 1am this morning, conditions poor. Captured in SharpCap 2.10 with the ZWO ASI224MC, Celestron UV/IR cutoff filter, Tele Vue Powermate 2.5x, focal extension tubes and the Celestron Nexstar 8i SCT. Focal length approximately 5420mm, just under f25 if my calculations are correct. First time imaging with the Powermate. I spent about 2 hours editing the final stacked image of 679 frames from Autostakkert with 1.5X drizzle, Registax for wavelets and some colour correction, noise reduction, RGB Align and final edit in PaintDotNet for further colour correction, some sharpeni
  22. This is some great work Charl, amazing. I've been following the solar imaging section offline recently to check activity as I bought a glass white light solar filter for my C8 to compare to the solar white light film filter. There was a long time with no solar activity. So is this one of the DayStar Quark h-alpha chromosphere eyepiece adapters fitted to your ED80 and what's ERF? Could you point me in the right direction to what you bought please so I can read up on it all
  23. I just saw this on the main SGL page Charl and logged in to say WOW Excellent!
  24. I'm not sure on the Edmund Scientific focal extenders Sean, a quick search says that they are a Barlow design, but I could be wrong, they may have another design. I've never had any luck with Barlows visually or in imaging like you say. I have seen some great shots from people using Barlows but they just don't do it for me so I don't use any of mine apart from the 2" I currently use on the C8 as a focal extension tube, I just unscrewed the lens. I almost bought an Explore Scientific focal extender and have read good things about them but again I think they are the Barlow design too. I ended up
