  1. Imaged with a c9.25, ZWO ASI224MC at 12 degrees altitude and ADC. Difficult to make out detail at this aperture but more seen than at opposition. Used winjupos to derotate after the usual stacking of recordings. I hear will be better in 2020 - Martian dust storm and earth weather permitting
  2. Irrespective of dust storms - just goes to show seeing is everything. I have processed the images with identical profiles in registax and equivalent tweaks in photoshop to prove the point. ADC was used for all sessions.
  3. Very humid night on the UK South Coast with minimal breeze. My ADC helped a lot with the low altitude of the planets. Look forward to the Martian dust storm clearing up some more before Mars starts shrinking again as an imaging object.
  4. Thanks guys and yes I forgot to add in a skywatcher dual speed crayford focusser. I dont usually have any problems achieving dslr focus without the focal reducer but adding one in causes me difficulty.
  5. Dear all, I am relatively new to the concept of backfocus. Please can you advise which spacers would be required for the following combinations of equipment: 1. DSLR to C9.25 and 0.63 Focal Reducer 2. ZWO ASI224MC to C9.25 and 0.63 Focal Reducer 3. ZWO ASI224MC to Altair starwave ED80 with 0.8 Focal reducer many thanks in Advance. Please be gentle with my ignorance
  6. I have started imaging late this season due to house moves. Saturn is pretty tough this year.
  7. Somehow manged to coax reasonble detail with the help of an ADC despite the altitude of 14 degrees in West Sussex. I have looked at the firecapture log and a bit confused as to how it works out that the image was taken at f40. In the image train was a c9.25 scope, a skywatcher dual speed focuser, a x2 Barlow, astrosystems holland ADC then the zwo asi224MC camera.
  8. Wow, the experts can do so much better than me with even average data in average seeing
  9. Jupiter taken on the 26th May. Images derotated in Winjupos from 5 avi's caught in firecapture then sharpened in registax and finished in photoshop. ASI224MC camera on C9.25 scope and x2 Barlow
  10. In retrospect was a little bit unlucky on the 26th May in needing to stay up with the kids a bit and missing my chance to have imaged the impact on Jupiter that evening 3 hours prior. Enjoyed the good seeing for a bit. Then gave up when I had a go at Saturn and got put off by it's awful appearance at it's low UK altitude. Anyway the image is derotation of 5 avi's - each 20% of 5000 frames. Programs used: firecapture, registax, winjupos, PS. ZWO ASI224MC, C9.25, ADC and x2 Barlow. I have probably oversharpened the image - I am not used to getting so much detail on my imaging runs.
  11. Yep will have another go with the winjupos
  12. derotated with winjupos. still havent got the hang of photoshop and of course the moon io gets smeared
  13. yes I used a x2 Celestron Xcel barlow
  14. Jupiter from the 8th of April 2017. 6 x 2 minute avi (50% of 3000 frames each) derotated in Winjupos. C9.25 with ZWO ASI 224MC and ASH ADC.
