Hello, all.

I was imaging the nearly-full Moon last night and found I was vastly over-exposed when using a scope of f6.3 to f7 and the ASI2600MC-P.

Even at the very shortest exposure possible, my highlights were blown out and just barely salvageable.

I'd like to buy one or two Baader ND filters, but not sure which ones. If these are for half-Moon to full-Moon, which Baader ND filters are the most usable?

Many thanks,

Bob

Ask the folks in the Lunar Observing and Imaginv Forum. This is Planetary Imaging not Sun and Not Moon and Not Comets. The description next to the forum title explains quite clearly.

I have both the ND-0.6 25% and ND-0.9 12.5%. I try both of them each night to see what best suits at that time. If I was to go with just one then the ND-0.6 would be my choice.

 

It is hard to get rid of all high exposure areas without losing some detail.

 

Good luck,

Ken

Many, MANY thanks. Exactly what I hoped to learn.
