Had my first light moment...

I had my first ligjt moment last night. All I have is a Baader zoom eye piece at the moment. The field of view at 24mm was very rich. So can not wait for the William Optics 25mm Swan and the 40mm. With the William Optic 72 deg FoV, that maybe the first and last time I use the zoom eye piece. I just know it is going to be spectacular.

Good Value

The Williams Optics 25mm 2" eyepiece is a solid performer and an order of magnitude better than the 1.25" 25mm Possel that come standard on many telescopes. I would say its a good 2" Wide Angle eyepiece at a very reasonable price - very much worth the money. While the Williams 25mm 2" EP is a good eyepiece the Williams 40mm 2" EP is a special eyepiece .

SWAN 25mm 2''

Ocular optimo para focales mayores de F6. Tiene un uso de campos medianos como el doble cumulo de perseo. El ocular tiene una construcción muy bien terminada y con buenos materiales.
