Callisto and Ganymede shadow transits

2021-10-06T10:25:16+00:006 October 2021|Jupiter, News|

Poor seeing so not much detail visible on Jupiter so concentrated on the shadow transits. Seeing comes in and out through the session. 13 frames in an animation. Satellite visible is Ganymede. Callisto is much further out and so the Ganymede shadow catches up with that of Callisto.

M31 tri-band test

2021-09-24T21:10:18+00:009 September 2021|Galaxy, M31-60, Narrowband, News|

Test to see if imaging M31 in tri-band is worth it. Yes! Detail in there that I haven’t seen in other images I’ve taken. Planning a 6 pane mosaic of the galaxy.

Horizontal banding sorted. Camera into USB 2 not 3, and not through a USB hub.
Not very happy with the processing.

IC 1396 Elephant Trunk Nebula

One I often observe for HOYS but purely for imaging this time. Some horizontal banding noise from somewhere – to be resolved.
