Ring Nebula with Touptek Mono

[Stub Mandrel]

Not a spectacular image - this little camera has a webcam sized chip, the same as in the  ASI120MC, but the mono version.

This is the best of 125 16-second frames stacked in DSS without flats darks or bias. The little companion galaxy is visible but my skies hide the outer envelope.

Amazing image for such a little camera 👍🏼

Indeed.  I'm impressed.  Particularly that you've picked up the galaxy as well.

I want to try LRGB with it, so I'm going to see if I can make an aluminium clamp to put a peltier cooler on it. Then I can go for 5-minute exposures instead of 16 seconds!

I wonder if it wouldn't be pretty much as easy and more effective to machine a completely new housing?

Good point, I can make sure there's good thermal contact between the chip and its housing. Plus I could fit a  plastic nose to stop heat being conducted in from the scope.

There goes my weekend...

Hmm... -it's surprisingly well designed, lots of ways to do this

On the assumption you go ahead, please do post a thread about it.

Can you imaging me not doing that 🙂

Very nice! Great that you've managed to pick up some of the background galaxy. Cooling the camera and longer subs should be very interesting
