The Cosmic Question Mark

My latest image from the backyard is the 'Cosmic Question Mark Nebula' in the constellation Cepheus.

 

This target includes a large, bright emission nebula (NGC 7822), with a nebulous 'point' at the bottom (Sharpless 170).

 

If you're in the northern hemisphere, Cepheus is full of photographic nebulae, including this monster.

 

I used an ultra-portable telescope setup for this one, a wide-field refractor and a one-shot-color astronomy camera.

 

Equipment Used:

 

Camera: bit.ly/3zuuEvO

Telescope: bit.ly/3YAoO6s

Filter: bit.ly/4b6MV0F

Mount: bit.ly/4csp0bn

 

Total Exposure: 6 Hours (72 x 5 minutes)
