Wonderful photo. I had a go last night (01/04) after months of cloud cover. Having a few problems with sky glow though, any tips? Will give it another go tonight with a 50mm considering its moving upto the Andromeda galaxy. Lets hope for clearer skies


Snappy Happy with a K10.

Hi D

Thank you, been quite clear most nights here but strangely not last night!

Hope you get a chance to see it though you will need binoculars to pin-point it...if you can find the Andromeda Galaxy then you should find the comet close-by.

Light pollution is an increasing problem so I stay portable now to avoid that frustration!

The 50mm lens should be good for a wide field & better if a fast lens too, with a stationary camera try 800iso & 1600iso with exposures up to long you can expose depends on your local light pollution.

Good luck D!
