  1. The Io and shadow transit of 6/11/2023 with Ganymede to the right (W). On the original, the bright patch to the top left of Ganymede is clearly visible and matches the spot shown using the SkySafari simulation. Io is just to the right and below its shadow. The GRS is just going out of view, bottom right.

  2. Rather poor astronomy weather recently so any clear spell is appreciated. The seeing was a bit below average, although it came and went as waves of something or other passed over. I imaged the transit until hypothermia took over - this is just after the start of the shadow moving onto the disk.

    . I don't think you need a C14 for imaging

    TVM Reggie. Unfortunately though, 

    2xAperture = 2xResolution, 4xLight flux and 0.5xNoise.

  4. The hot weather has produced some decent seeing, with glorious views at the eyepiece, and a sharper image stack with the camera. For me this year, last night was the first time that Enke has been clearly defined. 6000 out of 30,000 frames.

  5. Thank you for your kind comments. If only the UK weather would improve and give us a run of warm evenings with excellent plus seeing while Saturn andJupiter are still at their best! This year must be one of the worst I can remember in more than 50 years observing.

    This gives me encouragement to try for Dubhe with my 178mm Intes Micro Mak. It's a double I've not considered before now.

    Certainly splits with my 180 Mak. The secondary touches the 1st diff ring, but if the seeing is good, it can be seen as a separate disk (see other posts here re Dubhe).
