Re: APOD: Circumpolar Star Trails (2019 Jan 18)

The observatory was not operating on that clear, dark night, but that's not surprising...
This begs the question - why ever wasn't the observatory operating on a clear, dark night?

Looks like some old fashioned contorted altocumulus lenticularis to me.

Re: APOD: Barred Spiral Galaxy NGC 1300 (2016 Jan 09)

A really great image, but you've used the exact same image before and it's a big universe. Any chance of seeing NGC 1299 or 1301? Perhaps they aren't quite as impressive as NGC 1300 but at least they would be new.

Couldn't the antenna be positioned mechanically with electric motors powered by solar panels?

Or is it maybe that the whole satellite's attitude needs adjusting to point back to blighty because the dish is rigidly fixed to it?

Re: APOD: Comet Siding Spring Passes Mars (2014 Oct 20)

Its a shame that you couldn't have created an HDR image, where Mars had a shorter exposure to make it less bright and exposed, and the comet could have received a longer exposure to make it visible, or would that be impossible to do?

Re: APOD: NGC 6384: Spiral Beyond the Stars (2013 Jul 06)

Hi There's no doubt about it NGC 6384 is a great spiral galaxy - but we've seen exactly the same image a couple of times in the last 18 months. Most of the times when you show a repeat you show greater resolution but not with this one. I get the hankering at times to go where no man has gone before ...

Re: APOD: Messier 77 (2013 May 10)

Hi

I'm confused - if this is Messier 77 why does the one in an image from your site in 2006 look so much different?

http://apod.nasa.gov/apod/ap061207.html

I can't find that much in common between the two images and whats happened to the bright star in the 2006 image?

Bruce.

Re: APOD: Alaskan Moondogs (2013 Jan 26)

I don't believe this is a true moon dog or halo caused by ice crystals in the higher atmosphere, but as someone else said in an earlier post the phenomena is caused by ice crystals in the lower atmosphere, probably trapped in a temperature inversion in the lowest 300 metres. I think the effect is ex...
