Condensation on the exterior lenses occurs frequently when one returns from a cold environment to a warm environment. Even after it has evaporated it still sometimes leaves visible traces.

Hi,

Have you read up on some of the threads in the "Tripods & Heads" forum and read the tripod primer there?
The options you mentioned are IMO inadequate, particularly in your location, where wind...

Same here, a futile wait for a gap in the clouds - very disappointing.

Hi Ace,

For observing with an ATX 85 the Manfrotto 055 would be adequate in most situations but for digiscoping I think you would need something like the MT057C3. It's only 800 g heavier than an 055...

Hi mbb,

I can go along with most of what you say. However, I dont think the ATX 65 would be a very good choice. As you point out, it's a similar weight (and price) to the ATS 80, so if you get along...

Berlebach 510 Video Head vs. 552

For several years I have used a Berlebach 552 head on a Sirui M-3204 carbon fibre tripod and recently purchased a Berlebach 510 as a lighter alternative to go on a Novoflex TrioPod.

In no way is your tripod suggestion overkill. On the contrary, I have doubts as to whether it would be adequate. Asumming you are getting the angled MM4, you would be comfortable with a...

Out of curiosity I bought a cheap Nikon Aculon, which works satisfactorily up to about 500 m if you can hold it steady enough.

Chuck,

It's a rather miserable 15 mm. The 8x42 has 17,4 mm and the 7x42 a whopping 21,8 mm. I think Meopta scaled the eyepiece design for the three models going from short focal length on the 10x to...

John,

The dip is at the highest frequencies, i.e blue (shortest wavelengths) and the comparison is between a 7x42 FL and an 8x42 HT.
I'm not convinced that HT glass shows significant visual benefits...
