And here is the actual pinhole camera image (solargraph) itself. The topmost bright line is the Sun's path on the Summer Solstice (June 21st 2022) and the bright line at the very bottom is the Sun's path on the Winter Solstice (December 21st 2021). The two white domes at the bottom of the image are the New Forest Observatories. Greg

I replaced the original image with one taken on a higher resolution scanner. Greg

Summer Solstice today for us Brits and tonight I will bring in the photopaper from the pinhole camera that has been imaging from December 21st 2021 until today. Piccie of the pinhole camera is attached. Greg

A white Poppy and a Rose Greg

The good thing about the rings is that they are precisely the star colour as Noel takes the colour from around the edge of the star (keeping clear of the core where it is saturated - white). Greg

A reprocess of Aldebaran from 08/12 /2015 using the Sky90 array and the M26C OSC CCDs. This is a 2-frame mosaic with a total number of 66 subs at 2-minutes per sub. Greg

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.

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.

Yep - that's M97 Owl nebula and M108 galaxy Greg

This is another reprocess of old data, this time it's the mighty Merak in the constellation Ursa Major. This is a 4-frame mosaic using the Sky90 array and the M26C OSC CCDs. Total exposure time is 16 hours using 10-minute subs. Greg

Carbon star T Cancri from 14/03/2016 using the Sky90 array and the M26C OSC CCDs. This is 18 subs at 10-minutes per sub. Greg

Another reprocess of old data. This time it is the Heart nebula. A 2-frame mosaic taken using the Sky90 array and the M26C OSC CCDs. The upper half of the image is 24 x 20-minute subs and the lower half is 15 x 20-minute subs so the whole image is 13-hours of exposure time. Greg

In going through all this old data I found M45 data taken over 3 days and totalling 21 hours. So I put the whole lot together in Maxim and this is the result. Once again it's the Sky90 array and the M26C OSC CCDs. Greg

Another reprocess of old data. This time it's little reflection nebula NGC6914, the only bit of blue in a sea of red Hydrogen emission nebulosity. This is 51 x 20-minute subs (17-hours) taken on the Sky90 array with the M26C OSC CCDs.

The star spikes are just wrong so I got rid of them. Greg

My last revisit to this one for a while now. As per Noel Carboni's advice I went much lighter on the flattening and I also applied ZERO noise reduction. After all, with 30-hours of data you really shouldn't need noise reduction. Greg

It is in fact 30-hours of exposure time as all 4 datasets were 40-minute subs. I still can't find those extra 6 x 1-hour subs so maybe I just dreamt it? Anyway - here's a fractionally better reprocess. Greg

Taken in the garden in the last hour Greg

I just quickly checked if the GIF would upload and it seems it does Going through all my old data I found this 2012 transit of Venus which I downloaded (15-minute frame by frame) over the Internet.

I found another 6 hours of data giving 27-hours in total. Greg

I've just found my first gem in reprocessing all this old data. This is IC348 an open cluster and associated nebulosity in Perseus. This is 21 x 30-minute subs (10 and a half hours!!) using the Sky90 array and the M26C OSC CCDs. Greg

39 x 10-minute subs using the Sky90 array and M26C OSC CCDs. Carbon star U Cygni is the very red star towards top left of the image, lying just below a white star of similar magnitude in a faint wisp of Hydrogen emission nebulosity. Greg
