I have the Polarie and although it tracks quite accurately, when it is aligned well. I do like its accuracy; not a fan of the process though. The camera mount part has to be removed to insert the polar scope for "spot on" alignment. I've found that I almost always end up moving the mount when swapping the polar scope and threading the camera mount back in. An external power source is a must for extended use with any load even near the rated capacity.
I really like the different rotation rates the Polarie offers; celestial, solar, and a nice 1/2 speed setting that's great for time-lapse panning, (mounting the Polarie in a flat, horizontal plane). Also runs in reverse, (Southern Hemisphere).

I also have a Celestron SCT on an alt/as Go To mount. The Go To feature is great for "hopping around" viewing. Alt/Az mount is fine for visual viewing, but has limited tracking ability for Astrophotography without adding a wedge to give a decent polar alignment.

Budget issues aside, a Go To Equitorial mount would be the optimal choice...and while we're talking budget, ditch the 70-200 lens and go with a fast, (2.8 or better) prime lens.

The speed of the RAM could be affected by number of sticks. Depends on the motherboard and chipset. In some systems, memory runs slower with the more DIMMs used. Two sticks, matched of course, usualy provides the best performance.

And You know when I shoot alone,
I prefer to be by myself

OK, wondering about the handcuffs, the situation and the rest of that iceberg.
Perhaps a free-lance, parking valet practicing his craft?

I believe the falls to be Multnomah Falls. Nice shot, regardless of naming.

Very nice. Can almost feel the sun's heat on my face when viewing the download.
Where is this place?

I've been playing with this Earth Impact Program, and one of the results given is "radiant flux." I can find the definition online, but I don't understand how that relates to heat - or anything else. If radiant flux = 533, what does that actually mean?

For a particular impact, the wind speed might be 1,700 MPH, and I can understand that, but radiant flux? Can that be referenced as a temperature?

http://impact.ese.ic.ac.uk/ImpactEffects/


In radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted or received, per unit time, and spectral flux or spectral power is the radiant flux per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. (Wikipedia)

Ruminate on that explanation for a moment. I read it a couple of times for it to make sense; not enough times to understand it though.

Don't believe it would/could be expressed as a temperature

I don't know if you realize it or not, you could find yourself in heap big trouble if getting caught doing this. Now don't think it's something new it's not been a regulation for many years, i.e. firing of any live materials from a r/c acft is verboten.... oh is your quad registered?


I suspect perhaps shot from the drone; not launched from the drone?

Spent the week at Carolina Beach, NC. Up early every morning to greet the Sun and see what the tide brought in I found a Torpedo in the sand.

Don't remove the nose! Try teaching the nose better focusing techniques instead.

For those of you who don't know "The Knowledge" is the exam that London's black cab drivers have to take before they are allowed to pick up fares.

Did you know they have to learn off by heart, 20,000 streets and between 8,000 and 9,000 points of interest?


OK, sounds like a racist thing to me; an unfair way to keep backs from being cab drivers. Or, maybe it's all about the commas; Is that a black, cab driver?Or a black cab, driver?

Pretty sure my last Uber driver never made it past third grade, but he had a smart phone and an App. :lol:

I guess one could call it an orchestra sized, one-man-band!

Awe.. thanks! By no means do I think I am of Peter Lik quality..

Peter Lik isn't of Peter Lik quality. He is a (or hires) PR geniuses to inflate his reputation and according to many fakes his success through fictional figures. I take that back, he is a "flim flam" genius.

Someone called him the Thomas Kinkade of photography. I would go beyond that and call him the P T Barnum of photography.


strikes me as more of a J. Peterman type...like the guy from Seinfeld
