10 hours in one night of Sh2-155 - Cave Nebula

[Budgie1]

I love this time of year when you get a clear sky early on.

This was taken on Saturday 11th November and it was dark enough to start the subs at 18:30. I finished the run at just before 05:00 on Sunday morning, with a meridian flip & a laptop reboot in the middle of it. If it wasn't for the laptop reboot then I'd have got another hour out of it, but decided to call it a night at that point as I was also running a second rig with Samyang 135mm f2 & ASI294MC Pro which had to be put away.

I managed to capture a total of 10h10m of 300s subs:

• Ha 3.5nm - 3h45m
• Oiii 4nm - 3h30m
• Sii 8nm - 2h55m

The kit was:

• WO Z73 III with adjustable flattener
• ZWO ASI1600MM Pro set to -10° C, gain 139, offset 50
• Baader filters as above
• Heq5 mount with belt conversion
• Captured with APT & processed in PI

Processed as SHO but I only used the Ha stars for the final image.

Thanks for looking.

Lovely capture, I can never see the name for this one though.

Me neither, Alan.  Maybe it depends on the orientation?

Nice image, I like the colour balance and neutral background you have achieved.

Thats an excellent image. love the colours. What I would not give for a whole night clear with no moon!

[Budgie1]

Just a whole night, with or without the Moon, is a rare thing this season! 🤣

And for it to fall on a weekend when I didn't have to get up in the morning, how lucky was that! 😁

I am VERY unimpressed that you should get all that.🥺 Particularly in what is said the be the wettest place in Scotland (Expat Scot here)

Over here in the West of Ireland it has been unbelievably bad this whole year.

Oh, don't worry, it's still been wet. 86mm in one day back in October!

And I've had my fair share of 30 minute sessions then clouded over for the rest of the night.

Fortunately the Jetstream has been a bit further South than normal, so you're getting all the weather we normally do at time of year, and we really do appreciate you doing that for us. 🤣😂
