Got a little more data on the IC410/IC405 region last night with the 200mm lenses, ASI 2600MC Pro CMOS cameras and the Optolong L-Enhace filters. I am now up to 18 x 20-minute subs. If I can get another 12 … Continue reading
Apart from being freezing cold – last night was also cloudless and Moonless. Managed to get 24 x 20-minute subs (8 hours) on the California nebula with the 200mm lenses, the ASI 2600MC Pro CMOS cameras, and of course the … Continue reading
Got today’s EPOD with a 3D view of DNA. https://epod.usra.edu/blog/2023/01/3-d-view-of-dna.html
Having proved the efficacy of the utterly superb Optolong L-Enhance filters on the 200mm lenses (with ASI 2600MC Pro CMOS cameras) – it was clearly time to fit the same thing to my Sky90s (with Trius M26C OSC CCDs). 2 … Continue reading
Well good old Wolfram Research came through and they have published my Solid Golden Angle in their Notebook Archives. So at least it is now “out there” with a name associated with the discovery. https://notebookarchive.org/the-golden-solid-angle–2022-12-dtu824g/
I am 68 years old, nearing 69 and I have been retired since 2010. Therefore I have no job to lose by writing stuff that you might think could get me committed. And also I don’t have that many years … Continue reading
This is a composite image of the IC410/IC405 region taken using a Sky90 refractor with an M25C OSC CCD and a pair of Canon 200mm prime lenses with ASI 2600MC Pro OSC CMOS cameras. The Sky90 data was 5-hours and … Continue reading
This image is a composite of Sky90 and Hyperstar 4 data only.
This is the central region of the Rosette nebula. This is a composite image created using RegiStar and comprises original Hyperstar, Sky90 and Hyperstar 4 data exceeding 15-hours of total exposure time.
Another hobby of mine is “experimental mathematics” – I think I may have mentioned (ages ago) my Prime number hunting server. Well way back in June 2007 (just before actually) I discovered something that seems to have been overlooked for … Continue reading
