  1. I was trying to view this with my Altair GPCAM using live stacking in Sharpcap, and although it was there it was very hard to make out. Congratulations on a great image.
  2. Looking for the above or maybe a unmodified 1100d as well if the price is right.
  3. About sequence length, a lot of people use 90 seconds as a starting point. However the higher the resolution the lower the capture time. This is the equation that I got from another forum: Tc = res / (pi * D/P) where Tc - maximum capture time (minutes) res - desired "resolution" in arcsec D - planet diameter in arcsec P - rotation period of planet (minutes) If you put your camera and scope combination in here: http://astronomy.tools/calculators/field_of_view/ That will give you your resolution. This site will give you Jupiter's current angular size: http://www.skyandtelescope.com/wp-content/observing-tools/jupiter_moons/jupiter.html# Jupiter's rotation speed is 590 minutes. I would advise not using PIPP to select out frames, just order them by quality. Choose how many frames to stack in Autostakkert where you can actually view the frames and see where the quality starts to deteriorate. Stack as many frames as you can and that will increase your signal to noise ratio, your images will be less grainy after sharpening. I will say that I tend to favor getting as many frames as possible over the rotation issue. I took a 2 minute avi at 0.15" resolution and it turned out pretty well. I have a USB 2.0 camera though, if you have a high speed USB 3.0 camera you may want to do things differently. This is an interesting read: http://www.planetary-astronomy-and-imaging.com/en/maximum-video-time-jupiter/ The raggedy edge of the planet is probably caused by oversharpening or it might be a stacking artifact. The only way to tell is to experiment with stacking and processing.
  4. Both cracking images. Looks like you've hit the ground running.
  5. Wow amazing shots. Does the ADC make a big difference?
  6. Yeah looks great, is that the great red spot on the left limb?
  7. Thanks Si!
  8. Really good detail. If you don't mind a suggestion it looks like you pushed your wavelets or sharpening a little to far. If you dial back the sharpening or add deniosing or noise reduction that should get rid of the 'blocky'. The image is also looking a liitle green. If you're using Registax try using the Auto Colour Balance feature and make sure you're debayering using the correct pattern. I wouldn't mind one of them new GPCAM's. Great image!
  9. These two images were taken using an Altair GPCAM V1 and Skywatcher 200p on an AstroEQ Vixen GP. They were both captured with Sharpcap and processed with PIPP, Autostakkert, Registax and GIMP. The Jupiter image was taken with a Revekation 5x barlow. The Saturn image was taken with an Astro Engineering AC333 2x barlow. Not looked at all the data yet but this is looking like my best capture from last night for Jupiter. This capture also has Io to the right. 1300 frames stacked. Taken at 11:43PM on 10/05/17: This saturn image was taken at 03:11am on 11/05/2017. Best 50% of 5110 frames stacked: Saturn is going to be a challenge this year but I'll give it a go. Roll on mid June!
  10. Thanks Angie!
  11. Thanks SnakeyJ.
  12. Thanks guys. Next stop Saturn. Thats going to be a challenge.
  13. Thanks Michael. I kept going to about 1am. By that time the seeing was getting worse so I packed it in. Interestingly most of my captures were done in 12 bit, but this image is from one of the two 8 bit captures and it's by far the best result. The number of frames being stacked isn't that different so it must be down to seeing during that capture run. I still have some of the 12 bit captures to process so I'll see how I get on.
  14. This was taken at 12:27am last night. I used an Skywatcher 200p on an AstroEQ Vixen GP with a Revelation x5 Barlow. The image was captured with an Altair GPCAM v1 using Sharpcap. I stacked the best 50% of 3875 frames from a two minute AVI. The image was processed with PIPP, Autostakkert, Registax and GIMP2.9. w1 Final.tif Any comments or criticisms welcome.

    Cheers Bill, didn't know the central star was that faint, thanks.
