Mike, these really are exceptional photos, the technical aspect is well beyond me, but they make great photos!

Remarkable astro-photography, Mike. Quite amazing what you've captured, presumably from an urban setting with problematic light pollution to deal with.
Thanks for sharing.

I keep wondering what you could do at 10,000 ft elevation w Zero light pollution

Back to non-sony deep space objects... This is the Pacman Nebula.

As with many Nebulae, it's made from clouds of light-emitting ionized gas. Conventional SLR type sensors filter out that band of light rather nicely but an Astro camera can capture it quite nicely, given enough time.


Here's the first one - conventional R/G/B capture with the ionized stuff added in from Ha and Oiii frequencies. Ha is deep red (near infrared) and Oiii emits in the blue range
Pacman Nebula RGB Ha Oiii


(Just over two hours of exposures)

Keeping just the 'narrowband' exposures from the ionized gas allows for some experimental fun with mixing the colours (eg, the Hubble images are usually false colour, but look great

Pacman Nebula - Ha and Oiii


I think I could do better but work and cloudy skies have frustrated me this year!

As a comparison, here's a version from the A6000. It's rotated and at a wider focal length but you can see how much red is missing...

    Nice pics. I was hoping to get some pics myself, but it was too cloudy.
    Plus, I might not have woken up ...

    How wonderful to see all these red moon pics!   I rather like it with mostly red and a hint of grey - it really helps the 3d effect which it often missing from full moon pics.

    I woke up nice and early for work to find a blanket of cloud covering our region. Ho hum.   I still hoped to catch a glimpse at work as totality was due to continue about half an hour passed my planned take off time. No luck there either - we'd turned to face east just before breaking cloud, leaving the red moon nicely hidden from view behind us.. Oh well. Ho hum.

    Also thanks! I hadn't even noticed that light beam in the lower right corner... I was too fixated on the moon I guess…

    Great work here, it's nice to see all the different moon positions from different places on earth

    Here's another one from me that didn't turn out too bad (never imagined the blood moon was so dark) so it needed a much higher iso/longer time than I expected. So this picture isn't the sharpest. It's taken at 5:42, just before the whole shadow of the earth covered the moon completely

    It was clear, cold and very windy here in Atlanta. Wind chill between -11 and -12C and wind gusts to 64 kph. Really didn't want spend a lot of time outside, but here's a couple that weren't too bad.

    Some beautiful images here, and it's interesting to compare with the view of the blood red moon eclipse we had in the Southern hemisphere about a year ago on 31 January 2018. Main difference of course is that the surface features we see are 'upside down' with the 'melon stem' crater at the top for us Antipodeans.
