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
This image is just 8 x 20-minute subs on the 200mm lenses with the ASI 2600MC Pro CMOS cameras AND the Optolong L-Enhance filters. There is more signal in the Spider’s Web region in these 8 x 20-minute subs than … Continue reading
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
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
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.
This is the original Parker/Carboni Heart nebula taken with a single Sky90 and M25C OSC CCD after star reduction has been applied.
