Grainy

Hello All

Is the grainyness of the below imaged caused by the moon it was taken on the 27/8th there was quite a bit of moon about, or is there some other issue. 

I have recently change focuser to a new moonlight one, but in doing so i change my whole image train adding an LP filter to the front and increasing the distance to 56.5mm. Just a bit worried that this change has caused the issue.

Image details :-

SWED80 x.85

Atik 428EX Mono

12 x 600

Filters IR/UV cut and SW LP filter

Simple levels and curves in Ps

yer mate it looks a lot like moon wash,still a lovely image,well done,thanks for sharing. charl.

Yes, a near full moon washes out the image, LRGB is a waste of time. The only option is to go to narrow band (H-alpha) but even then you get increased background. If there is the slightest amount of high cirrus/mist etc., in combination with moonlight then you can forget doing any imaging at all.
