Pleased that Astronomy Magazine March edition printed a correction detailing that is was my image of the Jellyfish Nebula on the front cover of their January 2024 edition. #astronomy #astrophotography

Saturn - 11/10. Shocking seeing but considering it was the only 1/2 hour of clear skies I have had for the last week thought I'd give it a go.

True but as DSO fanatic I always call it the Devil’s Lightbulb :-)

The Moon 8-10-2025. It won't let me image any DSO's so I thought I would image it instead.

Fantastic detail in there Kev. I have decided to bite the bullet and go for an IMX571 sensor mono camera. Just got to decide which one now. :-)

Thanks Mike. What made you decide to go for the Touptek price or other features?

Martin Bracken - FRAS -CitySpaceAstro @cityspaceastro.bsky.social · 16d

Looking for some advice.
I want to buy an IMX571 Mono camera. Quite a few on the market ranging in price. Any recommendations or a comparisons? I hear the more expensive cameras have the best sensors in quality control and the cheaper ones don't. Does anyone know if that is true?
