Summer Solstice 2022

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.

Aldebaran with Ring Flare

I reprocessed Aldebaran with ring flare so it would look similar to Spica and Arcturus.

Epsilon Cassiopeiae and Greg’s Lambda

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.

Kemble’s Cascade

This is Kemble’s Cascade in the constellation Camelopardalis – and in this image the Cascade has been made more apparent by using the Akira Fujii effect. Another old data reprocess from 22/09/2015. This is a 4-frame mosaic using the Sky90 array and the M26C OSC CCDs. 3 of the 4 frames are 12 x 10-minute subs, and the 4th frame is 15 x 10-minute subs giving a total exposure time of 8 and a half hours. This is a large crop to centre the cascade.
