      HI Craig - thank you for your kind words. I have my new Player One Saturn-M. Very pleased with it for both solar and live stacking. The problem is the venerable ZWO ASI224MC still works really well so I am loathe to spend more money upgrading when the old kit still works fine.
      In meantime, may I ask what camera you have?

    Thanks nice talk through.
    10mS exposures and grainy images?
    So a big aperture 480mm f6.7 cdk would give less noise?
    Equipment didn't develop over last 20 years as I hoped. DIY telescope covers too small area for current affordable camera sizes.
    200mm secondary is going to reduce advantage of large primary, but is it worth finishing and mounting?

    • @RefreshingViews
      @RefreshingViews  ปีที่แล้ว

      each frame at 10ms is grainy but of course 1000-off 10msframes stacked together are not so noisy. Good luck with your CDK project - a 480mm scope sounds wonderful!

    I am just starting on my planetary imaging journey and I have all the gear assembled. I also have a grasp of the processing steps. I am unsure on one aspect of it and that is the capture format. Is it RAW or AVI etc. Thanks Mark.

      Hi AN - thank you for your message. You definitely want to be shooting in video (rather than 1000s of stills). I would suggest using SER simply because that’s what the pros recommend. That being said I’ve not seen any loss in quality using avi format. Defo video, ideally SER if not then AVI.

    Nice video. I did not see you used an ( ADC ) Atmospheric Dispersion Corrector. Did you use one?

      I always use an ADC especially with the planets being relatively low from the UK.

    Great Video Mark. Your tutorial videos Are Fantastic. I look forward seeing Your workflow on Mars. Especially with Softwares like 'Winjupos'. I used the Cartography tool 'Lambert equivirectangular projection. Though It doesn't really show much Detail, perhaps the Resolution of my mirror limits it. Cartography with Jupiter is Pretty cool, in Fact I want to Compare how Jupiters Surface changes in Just One Year!

    How did you get such a large Jupiter? My 16" is using a 2.5x barlow at F20 with a 2.9 micron pixel camera, but yours is almost 50% larger, when comparing mine in AutoStakkert. What resolution did you shoot your SER video? I was shooting 1024x768 at over 186 fps and got over 15k frames in 90 seconds.

    • @RefreshingViews

      Hi Mike although it is hard to know with a moving primary mirror, I think I am around f22 or so with my barlow spacing and 3.75um camera pixels. I use the Region of Interest to reduce the image size (something like 600x600 px from memory) - this increases the frame rate down the USB and reduces the file size by not recording empty black space.

    Nice capture. Am wondering how 'seeing' is defined by actual seeing (as in actually captured, rather than an estimate using a 'clear skys' weather app)?

    • @RefreshingViews
      @RefreshingViews  ปีที่แล้ว

      Good question! From reading online professional surveys measure the distortion of an Airy disc. As for forecasts I guess they correlate the turbulence and wind speeds in the upper atmosphere.

      @@RefreshingViews Great! I have learned processing from your videos, only difference is that I take pictures by Sharpcap.
      I never get resolution on C8 like yours, despite having well better conditions in Texas. Thus, autostakkert shows more quality frames. I could go up to x3 Barlow. But, your outcome is better.
      So, scope size could be important contributor.

      Thank you for your kind words - that’s the beauty of editing! It is relatively simple - although a lot of astrophotographers do like to up the complexity to bring out the last smidge of detail.
