Astrophotography / Blue Horsehead IC4592 from DSC

Last post by Carole - May 12, 2024, 14:17:51

Was pushing my luck with this target, but it has been on my bucket list for some time and one of the reasons I picked these particular dates for DSC.  If we had booked a month later it would have risen earlier, but there would be less dark sky and hoards of Joe Public on site.

It didn't rise until after midnight, and disappeared by 3.20, so only managed 2 hours 40 mins.  Could have done with 2 nights on it, but as we only had 2 clear nights and those were both a bit iffy, I had the wrong scope on the rig the first night I could have done it, so just continued with my early target.

Samyang lens and Atik460EX
2 hours luminance and 40 minutes binned RGB.
Total imaging time 2 hours 40 minutes

A great collection Roberto, I will have to get cracking on the imaging report now I am back from DSC.

Been at DSC and only realised there was something afoot when I saw the massive sunspot group on Sue's Ha Solar scope.

Was in transit on the Friday evening and only managed some Smartphone images of the display.

Thank you Fay!  I wasn't expecting the aurora to be visible from London TBH.  I had actually left my scope imaging after doing some double star observing and gone to bed.  When I checked the weather before going to sleep at 11pm I had one last look at the allsky camera and saw the sky pink!  Dragged my wife out of bed and called the neighbours!    It was magical.  I could have stayed out all night.  Ended up packing at around 1AM.

Last night the sky was reddish overhead and very green to the northern horizon.  No light curtains though. The seeing was excellent and I managed to observe some doubles I had not been able to low on the horizon because of it.

Superb collection Roberto. I am disappointed I was not tuned in enough to the aurorae. Was at  Bough Beech last night with JOhn D and Chris, but it did not appear. I did see the sunspots, through the societys Coronado, while visiting Cairds

My meteor cameras caught auroral activity most of the night. It didn't do the meteor detection many favours, but it's not something that happens often. At some point I will try to get something of the night's activity into the gallery, because it was a spectacular display. The world's news and social media sites will probably be full of photos far better, though.

...and an X5.4 flare around sunrise.

This solar storm is one of the biggest ever recorded.
