2 Questions for you....

[johnsmith]

Hi,

I would like to know:

1.   Is there difference between ''comet hunter telescope'' versus ''normal telescope'' on you website?

2.   Can we see shipping charge when we order or your website and how is calculated ?

Thanks

Hello John,
comet hunters are very fast, short FL refractors used strictly for a low power, wide field observing. These scopes are also called rich field telescopes. They are specialized for viewing deep space objects like galaxies, nebulas, open clusters, details of Milky Way, etc... typically (depending on type of objective lens), the maximum recommended magnification of these rich field instruments is held within 0.25D to 0.75D range.

Other achromatic refractors have longer focal length, narrower field of view and depending on actual F-Ratio they are offered in several sub-categories for the following types of observing:

1. F7 to F10 - universal, all-around performers good for deep space, Moon, binary star, planetary observing. These scopes offer good average performance on all these objects. They are too slow for truly excellent DSO observing and too fast for truly excellent planetary observing. But if you are looking for one scope for all styles of observing, this is the one for you.

2. F10 to F12 - these scopes are very good for Moon, planetary, binary star observing and you can also observe some brighter DSOs in good image quality.

3. F12 to F15 - these refractors are excellent for observing of the Moon, planets and binary stars but they are not performing well on most deep space objects except for some bright globular and open clusters and bright galaxies and such.

This is a very basic reply, but it should give you an idea what the Comet Hunters are used for as well as other styles of our achromatic and R30-R35-R50 refractors. The above mentioned is not true for Apochromatic systems. I hope I won't be criticized for this very simplified answer.

Regarding shipping charge, we calculate this individually upon request. Contact Mike Harden for more details [e-mail]
