low cost binoviewers for high power viewing: more?

Posted By Andrew Amundrud
Are there any reviews of the current UO bino? The appeal is that they are offered with orthoscopics, but the binos don't appear to have self centering collets. My goal is planetary viewing requiring a small fov. I have a 10"/f4.7 dob with equatorial platform.
Magnification will be done ahead of the bino using barlows placing less demand on the collimation of the bino. I was thinking of using only one pair of eyepieces, maybe 18mm. If not interchanging eyepieces, can I get by without self centering collets? Will this unit, used in this way, be satisfactory for magnifications of say 160-200x? I know the Denk Standard may provide the best of all worlds, but would the UO with orthos be a good start? I thank you again for your experience.

Hi,

I changed a few color levels in Photoshop and tried to get some more detail out of the picture.

>>>>That combined with the incredible design of the micro world, in which everything is made of basic constituent parts, which in turn are made out of nothing smacks of some higher design or order<<<<

This is also where I have trouble with the theory of evolution. There are basic structures on a cell level that have many parts working together with no explanation of how or when they came together. There is no "more basic" structure they could have evolved from. It might be just a matter of time until evolution unlocks these secrets. If anyone knows any good books on this topic let me know.

Sincerely,

a trip to Mars for the budget-minded

Mike,

It's all in the patience. We set the finder scope carefully and just move the telescope small amounts. You want to predict the path of the planet and allow it to pass through the fov while the scope is settled (focusing is quick and "yeah, that looks pretty good" in the 5 seconds that the planet passes through the fov).

We have been building a platform for the last 5 months and it is nearly complete (we have all the pieces, just require someone to put them together).

We all agree the single most important thing is seeing (and colomation, aperature, tracking, and good optics). When the platform is complete it will be nice to try shooting ~F30.

Sincerely,
Andrew

Processing Challenge

Hi Cris,

Thanks for the challenge! I left the image the same scale, adjusted wavelets slightly in Registax, and finished with some minor level adjustment.

Clear Skies,

Andrew

Thanks Paul for these little gems. You have brought encouragement with a reminder of the adage that sometimes less can be more. Take heart with your seeing in Minnesota. The 1 to 10 scale we might use to rate seeing here on the west coast would make Minnesota a 37.

Thankyou all for commenting on the more practical considerations for purchasing and using low cost binoviewers. I really appreciate these forums.
