I got 29 x 4-minute subs on the Hyperstar 4/ASI 2600MC Pro CMOS OSC CCD last night which I added to the 10 x 4-minute subs taken last year. This is the result. Not a huge improvement – but a … Continue reading
As I have access to the original data, I was able to look through the 50 subs and then threw out 16 which had “blobby” stars. So here is the sharper result using only 34 of the original 50 x … Continue reading
Well this is quite extraordinary. I discovered a huge pile of DVDs last week and I just spent a few days downloading them all onto an HDD. The data was all very old (mostly around 2005) and is all taken … 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
Noel worked his magic on this superb California nebula process which shows the extent of the “nose” on the front end of the nebula which is often missing in smaller field-of-view images.
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.
