  1. Hmmm Any prices listed at loron91423.tripod? Hmmmm :hello1:
  2. Welcome! Have lots of fun
  3. ALBERTO MONTALVO He knew it all the time! "IT'S THE PLANETONIAN" Guess who? In late September 1990 turned in early reports of a large storm on Saturn? To find out read Sky&Telescope December 1990 page 591 and February 1991 page 144 :hello1:
  4. Thank you for your comments on our thread. As to the f/number the visual brightness of an object depends on the telescope's aperture not f/ratio. In photography it is a much different matter then in astronomy. If one has a well made optical system in their reflector, the investment into a 3 vane system is well worth it.
  5. Chester Brandon having been a designer as to the NORDEN bombsight in WWII developed a series of oculars that have become most popular with astronomers because of their fine quality derived from their optical design. They are in focal lengths of 32mm, 24mm, 18mm, 12mm, and 8mm. Yes they are exspensive but well worth the investment for your planetary telescope system. Many well known astronomers references to their experience using the eyepieces which are sold through Vernonscope&CO. The contrast for the moon & Saturn is excellent. With Brandons, there is a dark background surrounding th
  6. Astronomer Alberto Montalvo taught me that there is such a thing. Several very important elements are required before a reflector can be considered for the study of the moon, planets, and the sun. (Remember however that no reflecting telescope will yield as good an image for lunar and planetary work as a refracting telescope does because of the optical design not because of certain design type or manufacturer or craftsman.) Refractors and reflectors are different telescopes because they are designed to do different tasks but a reflector can be made to perform well for lunar and planetary study
