BTW, Rod confused D & G Optical with DGM Optics, the company that is actually carrying the filters.

I've been happy with mine.

Vince,

That appears to be a first class effort. May your skies be clear ones.

NGC 7479 is an excellent galaxy for large apertures. I've observed it through 20 to 25" telescopes and have been able to make out its tightly curved spiral arms.

Unfortunately, the Sky Scout costs more than many novices are willing to pay for a telescope.

There's an article on AES and their "wind farm" proposal at http://www.bradfordera.com/site/news.cfm?newsid=17332245&BRD=52&PAG=461&dept_id=569780&rfi=6

Wind farms may not be all they're cracked up to be.

I find this situation quite ironic given the money the state is spending on CSSP and promoting the Pennsylvania Wilds.

The Bright Star Atlas 2000.0 is a very good beginners star atlas and is quite inexpensive.

Another good one is the Edmund Mag 6 Star Atlas.

If you have a Telrad, the various Sky Spot Telrad Finder Chart books can be very useful.

My 101mm Tele Vue refractor and 35mm Panoptic (4.4 degree TFOV) display NGC 7000 quite nicely from dark sites, particularly when an OIII filter is utilized. The nearby Pelican Nebula is a bit more difficult.

NGC 55 is a bit too far south for worthwhile observation from Pennsylvania but NGC 253, the Silver Dollar (or Coin) Galaxy, is certainly fair game. I've seen it from here through quite a variety of telescopes ranging from 80mm to over 20 inches. Obviously, NGC 253 is a large galaxy and rather bright. The spiral galaxy NGC 247 and the globular cluster NGC 288 are in the neighborhood.

I've had good views of galaxies in Microscopium, Piscis Austrinus, Sculptor, Fornax, and Eridanus from New Mexico (30-inch Tectron) and the Florida Keys and even better views from the Bolivian Altiplano. NGC 55 looked very good indeed through a 22-inch Starmaster from Bolivia.

The Fornax Cluster is one fantastic galaxy cluster. My friends and I spent a lot of time roaming through it with the 30-inch.

The great barred spiral NGC 1365 is one of my favorite galaxies. It looked almost photographic through a 33-inch ATM Dob at the 1996 Winter Star Party.

I've used the 4mm BO/TMB Planetary eyepiece in my f/5.4 Tele Vue refractor and have been pleasantly surprised with its performance.

It is my understanding that coma is not a major optical aberration in eyepieces.
