Sterrenland Posted September 6, 2021 Share Posted September 6, 2021 Was good to be under the stars again last night...decided to try the Heart Nebula for the first time. I found framing it quite difficult due to the FOV, but was pleased with the final orientation. The seeing was pretty good and I was quite pleased with the tightness of the stars. Overall I managed two hours of 120sec subs. I'm not sure what the 'ringed' star is to the left of the Nebula (I've included an enlarged image below)...it was the only star in all the subs to have what appears to be rings around it. I obviously suspect it might just be an 'artefact' fo some kind, but cannot understand why it only affects this one star. I did check in Stellarium, but couldn't really see what it might be. 6 Quote Link to comment Share on other sites More sharing options...
Sonyme Posted September 7, 2021 Share Posted September 7, 2021 Maybe it's a Dyson Sphere!! I'd be delighted with a shot like this. Gary 1 Quote Link to comment Share on other sites More sharing options...

TerryMcK Posted September 8, 2021 Share Posted September 8, 2021 I was intrigued and had a look on Stellarium and in Simbad. It is V559 Cas a double star http://simbad.u-strasbg.fr/simbad/sim-id?Ident=V*+V559+Cas Not sure what the outer layer is but on Simbad it shows up as a halo around the large star 1 Quote Link to comment Share on other sites More sharing options...

That's a very useful link...going back to the portal page when you search it brings up a host of helpful details - including image searches. Some of these DO show a blue-ish hue to the background star which explains my blue halo. Impressed my little 80mm and 294MC picked it up! 1 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted September 8, 2021 Share Posted September 8, 2021 Lovely image. The halo looks like a star has exploded behind. 1 Quote Link to comment Share on other sites More sharing options...
paulgrover68 Posted September 8, 2021 Share Posted September 8, 2021 Looks good - the Heart Nebula is without doubt the hardest object I've ever tried to frame. My wide scope is 345mm and I look at it and wish I had a Redcat. 1 Quote Link to comment Share on other sites More sharing options...
