wingeing Pom 762 Report post Posted July 6, 2021 I actually picked the wrong star. V1331 is correctly labelled below. 1 Share this post Link to post Share on other sites
wingeing Pom 762 Report post Posted July 6, 2021 How did I find out I picked the wrong star? Because I decided to take a look at the DSS data and put V1331 in the centre of the field - this is what I got. Greg Share this post Link to post Share on other sites

Radar 648 Report post Posted July 6, 2021 Very cool. Circumstellar disc (a mostly depleted accretion disc,,,posssibly). Ray 1 Share this post Link to post Share on other sites
timthelder 206 Report post Posted July 7, 2021 Interesting 'smoke ring' feature at about 11:00 from V1331 in the 3rd image near the top. Kudos, Tim. 1 Share this post Link to post Share on other sites
Radar 648 Report post Posted July 8, 2021 Tim very interesting. My C14 would be able to zoom right in on that. Cygnus unfortunately is a tad low for me. I did shoot it once, but I drove out to the bush, and then up onto a monolith called Kokerbin Rock, which gave me super views of the Northern horizon.

Yes - that is the DSS image and it is flipped top to bottom, so if you want the same area on one of my images, it's around 7:00 towards the bottom.
