Hello, the fruits of several nights down here in Tas recently when I wasn't working or it wasn't cloudy.
Tak 85FSQ and FLI 8300 mono with 7nm Baader ha filter.
I didn't notice the ringing around the stars till just now- can I get rid of that easy? ( I have Star Tools and PS5 )
thanks for any tips
Graham

looking good Graz! like the framing and detail.
tough to find any imaging time everywhere it seems! - sorry can't help with the stars. are you planning on going full NB on this one?

cheers

Looks like you have picked up a reasonable amount of detail in there Graham. Have you gone for longer sub lengths than your last attempt?

Nice work, Graham! Just wondering if the ringing is actually a halo or perhaps a bad sub in your stack? Hard to guess what it might be after the IIS image compression.

Cheers,
Rick.

Hi Graham,

You have a very nice FOV with your camera and scope combo :)

I do not know if there is a way of perfectly removing the halos...might be easier to inspect the subs as per Rick's suggestion. I feel the halos were caused by dew forming on the lens.

A good looking monochrome photo Graham.

Great detail and I like the composition.
