NB1 filter target

[Ken82]

So it’s clear where I am after 11 this evening and I want to try out this new filter. Unfortunately after 11 the good nebula targets have gone so what would be a good target ? 

I’m thinking the Leo triplet but not ideal for the filter. 

Also Is 3 arcseconds pixel ok for imaging the Leo triplet ? A little low I think??

M97 is a nice target

Looks great under OIII so your NB1 filter should work well.

Yea thanks for the recommendation ? would 3” arcseconds a pixel be ok for this target though ?

I would use this to check FOV on targets.

Select the Viewing or Imaging and add the rest.

You can also use this site to see what is available from your location. Its free, just sign in, select your location, what objects, deep sky, bright nebula etc and a list will be produced with some images and a graph to the right showing the rising/falling and time from your location.
