8.5" Mak

I regret to inform the more credulous among you that my post was an April Fool joke. Next time I'll post something more outlandish to avoid misleading anyone.

Let Hubble Die

Posted By Joe Bergeron

As long as NASA has astronauts lined up eager to volunteer for such a mission, the risk to them does not concern me all that much. They're adults and they know the risks better than anyone. It's not like the USA doesn't risk and sacrifice lives every day for far more dubious causes.

How long should a scope last?

Posted By Joe Bergeron

Reflective coatings eventually degrade and fail, but those sealed inside a catadioptric scope like an SCT should last for many years, even decades. The motors, wiring, and electronics in that fancy goto mount will almost certainly fail first.

Antireflection coatings should last forever unless physically abused.

Why the use of tangent arms on older GEMs?

Posted By Joe Bergeron

With a tangent arm you get the leverage of a very large gear without the expense of a very large gear. Before mounts were commonly slewed around the sky by motors, there was no great advantage to using a full gear in declination. Precision gears of that size are certainly more expensive than tangent arms.

As a bit of a Jaegers fan, I'd be happy to read your story.

Darkest site near southern California

Posted By Joe Bergeron

I lived in and near Canebrake for 3 or 4 years. It is dark and clear, but the seeing is almost always bad, and the wind can howl for days (and nights) at a time. Also the southern horizon is constricted because of the encircling mountains. You might want to consider the White Mountains. They have some high-altitude campsites that are supposed to be nice, though cold and snowy now, I suppose.
