ISS Pass Last Night

Unbelievably it was clear enough last night to have a go at capturing the 9:41 p.m. 7-minute space station pass. I used the Canon 15mm fisheye lens on the Canon 5D MkII ISO 100, f#2.8, bulb setting, and took ~10-second … Continue reading

Spica Deep Down in the Murk

Unbelievably it was actually clear last night AND there was no Moon. Choice was between Arcturus and Spica, and as I’d only done Spica once before with the Sky90 array, Spica won. Just as with the Sky90 array image, Spica … Continue reading

Is it Really Worth it?

Aldebaran

Only 6 x 10-minute subs from last night, so pretty noisy, but at least it’s the first image since November 14th 2023, so a major landmark. 200mm lenses and the ASI 2600MC Pro CMOS cameras. Need to take some new … Continue reading

First Clear Night in Weeks.

A couple of nights back we had the first clear night in many weeks. This is such a rare event it deserves an entry all of its own. So, starting at 7 p.m. I began work on setting up the … Continue reading

M31 – the Final Cut

I just found another 6-hours of 40-minute subs of M31 taken with the Sky90 array, and I added this to the earlier composite. You can see the result above and it is virtually no different from the previous result. I … Continue reading
