Re: [APML] a few wide-field images

Mike,
Looks like a good start.
The one thing I notice on the shots are the blue halos surrounding the
stars.  I'm surprised you're getting these with the 135mm Nikkor lens.  I
have used the 105mm Nikkor and the stars are color free.  May I suggest you
pick up a Lumicon Minus-Violet filter to reduce the halos a bit.  Although
Lumicon no longer manufactures them, you can put a WTB on the Astromart for
one.  I did this and got 5 replies from people wanting the sell their
filter.

Regards,

Chris
