This isn’t my deepest image of the Pleiades, but this dataset was taken over a couple of consecutive nights using the Sky90 array and the M26C OSC CCDs. This is 24-hours of total exposure time using 40-minute subs!
I just combined last night’s 24 x 5-minute subs 200mm lens single framer with an older 40 x 5-minute subs 2-framer also using the 200mm lenses. This is the resulting Arcturus composite.
Managed to get some imaging done last night. Arcturus with the 200mm lenses and 2600MC Pro CMOS cameras. 24 x 5-minute subs. Note the “Napoleon’s Hat” asterism at the bottom of the lower spike slightly to the right.
The collimation was quite a way out when I imaged the Leo Trio 2 nights ago, so last night I was expecting to spend the whole evening trying to get good collimation. In preparation for this I had taken off … Continue reading
IMAGING!!!!!Collimation was well out on the Hyperstar and I thought it was going to take all night to get good collimation. First tweak on the collimation adjuster and I hit perfect collimation – took all of 2 minutes. So I … Continue reading
It was clear last night with a thin crecent Moon about to set, so I fired up the Hyperstar 4 on the C11. Target the Leo Trio. 4-minute subs with a 1-minute dither so I was planning on getting 15 … Continue reading
Last night was the 8th clear night in a row – a new record. Previously I managed to blow all the power MOSFETs in the dome rotator, so I spent all Monday morning replacing same (8 MOSFETs to de-solder, remove … Continue reading
I am not able to keep up with the images I have taken this week as I am so unused to having several clear nights in a row. Having just changed over to UV/IR cut filters on the 200mm lenses … Continue reading
Yet another clear night last night – almost unbelievable. So as I had just removed the narrowband filters from the 200mm lenses and replaced them with the UV/IR cut filters, I had rather creased myself and wasn’t sure what … Continue reading
A couple of nights back I managed to get some 10-minute subs on the Rosette using the Hyperstar 4 and the ASI 2600MC Pro CMOS camera with UV/IR cut filter. I added this new data to a lot of previously … Continue reading
