Reprocess of all Hyperstar on all Sky90 Data – Median Mix in Registar

Another reprocess of the Rosette data – all the Hyperstar data was overlaid on all the Sky90 data using Registar and a mean/median mix.

Composite IC410/IC405 Nebulae in Auriga

And a last reprocess (maybe) on this one too. This is around 12-hours of Sky90 data added to 10-hours and 40-minutes of 200mm lens data giving a composite image of the IC410/IC405 region in Auriga – a total (composite) exposure … Continue reading

Composite California Nebula

I added 16-hours of Sky90 data (which added to the bright nebula core) to the 8-hours of 200mm data (which provided the only data for the faint “nose”) to get this result.

The Rosette Nebula – A Work in Progress

Here are just 10 x 20-minute subs on the 200mm lenses, ASI 2600MC Pro OSC CMOS cameras and the Optolong L-Enhance filters. If I can get 30 or more subs on this one it should start looking quite nice.

IC410 & IC405 as You Might Not Have Seen Them Before

Finally got a total of 32 x 20-minute subs on this one, so calling it a day on this for now. IC410/IC405 region taken on the 2 x Canon 200mm prime lenses with 2 x ASI 2600MC Pro OSC CMOS … Continue reading

Now 6-hours on the IC410/IC405 Region

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

The California nebula

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

Optolong L-Enhance Filter on the IC405/IC410 Region

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

Additional Hyperstar 4 Data for the Rosette

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

Composite IC410 IC405

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
