APO vs. Achro and comments on this scopePosted By Bill Meyers |
I would stay away from this scope. For that kind of money you can get a TEC 140 if you like refractors with wide fields, whidch will give you far superior images -visit their Yahoo group -- or a Mag1 10inch F/5 or 8 inch F/5 Portaball, or an 11 inch Staarmster ELT, all of which will give widefield views far superior to an 8 inch F6 achromat. the TEC has a much wider maximum field but less bright images; all the others have the same focal length as the achromat you mention and therefore have the same maximum true field, but they are all much brighter (except for the 8Mag1 which has the same brightness as the 8 inch achromat.The image quality of these scopes will be vastly better.
If you just love 8 inch achromats, go ahead and get it, but if you are at all unsure, consider these other scopes and call their manufactureers (usually one person) and talk over the pros and cons.
Of for much less montey you can get a Guan Sheng or Synta 10 inch F5 *same maximum true field, brighter and better image) and take your family on a European vacation with the money you save.
