This is a pinhole camera image (solargraph) of the Sun’s path in the sky from the Winter Solstice (lowest bright line) to the Summer Solstice (topmost bright line). For the first time I have left the image in colour as it looked better than the greyscale image. The two white domes at the bottom of the image are the New Forest Observatories.
This is a composite Sky90 array image of the Coddington nebula region in Ursa Major made up from 2 frames. Frame 1 is 7 x 20-minute subs from 08/02/2015 and frame 2 is 11 x 20-minute subs from 26/02/2015. The red star towards the bottom left hand corner is Carbon star VY Ursae Majoris (SAO15274, HIP52577).
A Sky90 array image from 03/03/2015 this is star V509 Cassiopeiae a yellow hypergiant star in Cassiopeia. 44 subs at 4-minutes per sub.
A 2-frame Sky90 array mosaic taken on 08/03/2015. Each frame was 18 x 4-minute subs.
Bright blue star Rho Leonis captured using the Sky90 array on 13/03/2015. 23 subs at 5-minutes per sub.
Today is Summer Solstice 2022 for us Northern Hemispherers. Tonight I will bring in the photopaper from the pinhole camera (image above) that has been tracking the Sun daily since December 21st 2021. Tomorrow we should see a solargraph of the Sun’s last 6 month daily travels.
I reprocessed Aldebaran with ring flare so it would look similar to Spica and Arcturus.
Spica – the Brightest Bluest star in the sky. Reprocessed 22/04/2015 data taken on the Sky90 array with the M26C OSC CCDs. 33 subs at 5-minutes per sub. Spica is Alpha Virginis, the brightest star in the constellation Virgo.
From 03-06-2015 a 2-frame mosaic of Arcturus taken with the Sky90 array and the M26C OSC CCDs. Each frame was 30 subs at 4-minutes per sub. In the 5 o’clock position is the asterism called “Napoleon’s Hat”.
Reprocessed data from 09/09/2015 – the bright star towards centre bottom is Epsilon Cassiopeiae (the topmost left star in the Cassiopeia “W”) – and in the 11 o’clock position is an interesting asterism I call “Greg’s Lambda” as noone else seems to have laid claim to it. This is a Sky90 array/M26C OSC CCD image with each frame being 12 subs at 10-minutes per sub.
