Arrived today well packaged!
Waiting eagerly till later on tonight when it gets a bit darker to try them out.
There was a small speck on one of them, which Im not sure if a dust speck or small dust speck sized chip. Isnt too much too worry about though I hope.
Gave them a quick few squirts with the air can, a small touch of a cotton ear bud, but it looks like it may be a small, small chip. Hopefully wont be noticeable during viewing.
The threading is a little thin it felt, but fits tightly after a few turns. NOt as well threaded I think as the Meade filters.
At half the price of the Astronomik filters I'm happy so far.
I'll report back on my findings later on.
Tonights Preliminary Targets:
Keyhole Nebula
