Thanks

Thanks Guys, will look into those options. Just to add I also own a Skywatcher evostar 72ED which I hope to use the camera with. And yes @bomberbaz looking for cooled.

I own a starlight xpress SXVF M25C. Had it some years but want to upgrade to a modern CMOS camera. looking at the ZWO options but I’m not sure what to go for. I want to use it for deep sky and am only interested in a colour camera, mono is a bit beyond me at the moment. I have a budget of £600 and looking at the second hand market. Any recommendations?

Great thanks

Thanks for that. I will definitely try stacking more calibration frames next time, maybe give the lights more time too.

Thanks. No filter used. Not sure what the glass is, the retailer I purchased it from doesn't specify it, or do other places it seems. Maybe there is a focus issue however the central spike on the bahtinov was right in the middle.

Went out last night and got first light on my new Skywatcher 72ED. Great to be out as its been a while. Managed to get some data which I processed today. As you can see there are a few issues going on and wondering what might be the causes. Things I notice are the stars are bloated, the large stars have halo/discs around them, the detail is a bit fuzzy even though I made sure the focus and PA were spot on, it's also become quite noisy. Here's a full list of the set-up... Scope: Skywatcher 72ED with .85x focal reducer Mount: NEQ6 Camera: Starlight XPress SXVF-M25C colour CCD Data: Lights 22 x 300sec, Bias x 25, darks x 25, flats x 25 Stacked with DSS, processed in photoshop

Many thanks!

Now that most street lights are LED, I'm wondering if light pollution filters are still needed as I was under the assumption that they only filter out the old orange sodium lights?

Thanks guys

Curious. What do people call this? I’ve heard it referred to as a barrel. Some call it a nosepiece. Is there a standard term?

Thanks. Great image!

Ok guys. If I go for this Samyang 14 what tripod would you recommend for it? I currently have a very light and flimsy tripod which has a dodgy leg so needs replacing. I’d say £50 to £100, happy with second hand if needs be.

Thanks Alan

I've been reading some more reviews about this lens and some people report fish-eye type distortion and vignetting, is there a lens that doesn't have these problems or are all 14mm in this price range like this?
