2MASS J21383981+5708470 in IC1396A

Been gathering HOYS-CAPS data on 2MASS J21383981+5708470 in IC1396A recently because of a possible increase in brightness. This has been stretched and processed to show details. Normal submitted data wouldn’t be.

Jupiter colour / infrared

Jupiter is so low that only half of the telescope could see over the lip of the dome, so effectively only a 125mm telescope – not 250mm! Surprised I got anything at all at this altitude.

Not much detail visible but the infrared version is much sharper, cutting through the atmospheric turbulence better, and shows the Great Red Spot as white. The SEB is clearly changing and shows white in the colour image. Is this part of the unravelling of the GRS that is reportedly happening?

NGC4565 / Caldwell 38 Spindle Galaxy

Processed 3 different ways – give different results, not sure which I like best. Still too noisy – need many more exposures.
Interesting edge-on spiral galaxy in Coma Berenices, surprisingly large (14.9′ x 2′) but faint (9.60 but surface brightness 13.3). It is actually intrinsically more luminous than the Andromeda Galaxy. First seen by William Herschel in 1785. Also visible lower right is NGC 4562.

18 panels were just enough. This is 3000 pixels reduce from the original 5000.
