How badly is the Astronomy Industry is on it's butt

Posted By Greg Nowell

There's a lot of low-end crap available from reputable dealers.

In an economic upswing employment expands along with investment. Wages rise but bottlenecks in the economy lead to rising prices of critical input goods; real wages tend to fall or at a minimum not keep pace very well with productivity gains. Profits tend to rise and speculative pressures on some asset categories may inflate some people's sense of net worth. But consider the case of most people: wages did not keep up with housing costs, and the only way more people got into houses was with fraudulent access to credit; in reality, most people could not afford houses that as a ratio to income were way over their heads, more so than historically. Ditto with oil: people were working and prices were soaring, real wages were under extreme pressure on multiple fronts.

In an economic downswing investment falls and employment contracts. Sellers are under pressure from unsold inventory and are also under pressure from relatively fixed prices (such as a lease on a store, and often, wages). So they cut prices to maintain throughput for example if you sell four scopes at $2.00 profit in one month you are better off than if you sell no scope calculated to sell at $8.00 profit; so you cut prices; and you also cut prices to pay for inventory that isn't clearing: it is in some cases cheaper to move the product than to send it back to the manufacturer. And the manufacturer in any case will come under similar pressure to move the product, and so, will cut the prices rather than take back inventory....another interesting option is to sell at no profit or even at a loss because no profit and loss levels of income, say 98% of breakeven, is preferable to folding up shop and 0% of breakeven.

The result is that in a recession *those who keep their jobs* have *higher purchasing power.* One need only look at the simple situation of the oil market. The recession has caused prices to collapse and if you're still working you enjoy wages that are effectively higher than when boom/speculative conditions had pushed the price up to $146/barrel.

Ultimately manufacturers cut back output in a recession and this decision contributes to the overall unemployment; it is possible to reach a new equilibrium at lower output and have things crank along at that reduced level.

Better than Naglers?

Posted By Greg Nowell

Trading is a nice idea but not an effective strategy. You are only appealing to the one person who is interested in a trade. Sell your eyepieces to the people who want them and buy the eyepieces from the people who want to sell them.

A similar principle obtains with regard to "complete systems." If you tell me I have to buy an AP900 to go along with your TOA150mm refractor, that forces me out of the game, I already have the mount I want. Better to break the stuff up and sell it to the people that want it.

It's not like people are sitting there drumming their fingers saying "I want to trade." If they want to trade they sell and buy somewhere else. Incidentally the "search" command on Astromart which many people use to flush out the "wanted" ads from the "for sale" ads will also flush out the "trade" ads.

So a lot of people won't even see your ad.

will this work...

Posted By Greg Nowell

I agree with the other comments. Moreover the long tube might will surely hit the legs of the tripod as the scope slews around. For a lightweight mount for a 5", consider a Great Polaris.

The other thought is to go with (a) a dob with digital setting circles, such as those sold by Orion or (b) a dob without setting circles. Such as the 6" star blast.

Most used eyepiece for 10" SCT???

Posted By Greg Nowell

In my C14 my most used eyepiece is the XW40. At f/6.3 you might consider the XW30.

Anacortes pics?

Posted By Greg Nowell

Well I checked out 9973 Padilla Heights road, Anacortes, Wa on google maps with the satellite pics and it looks like ATWB is in nice open country with a great bay/estuary thing going on. Looks lovely. From outer space the store looks like it is in nice open territory with comfortable parking. But I couldn't get a ground level pic....

I spent some time in this area when I was a kid. A summer in the improbably named Sedro-Woolley and several other summers on Camano island. Beautiful part of the world.

That's my desktop du jour. I change my desktop photos frequently, often with bird or astromart astronomy pictures. The seagull gets his turn! thanks Greg

Need help identifying Cestron drive and motors

Posted By Greg Nowell

If the motors go up to 32x they are Vixen motors with a Celestron plate on them, and their worth is substantial: new, about $400 so you'd want to sell around half that.

If the motors have 8x as their maximum speed and/or say they are made in China than their new value was something like $125 six or seven years ago and they ain't worth much.

The mount itself is a Vixen Great Polaris and that's a good mount. Seriously. A very good light duty mount.

How anti reflective....

Gilles

Well Gilles I don't like to rain on the parade but here is a simple humble C14 shot which I took, also with a flash, which you can see from the metal on the secondary holder. The glass is showing no reflection and we are at an angle as you were. I was putting some flocking in at the time. The corrector has not been cleaned yet as the project was not done.

So I'm thinking well maybe the Celestron coatings are as good as AP's (unlikely) or maybe the test isn't a very rigorous test? Along these lines I note that when shooting from an angle the light may not bounce directly back at the camera.

Are these OEM back of mirror markings?

Posted By Greg Nowell

I don't think there's a serial number on the mirror. The orientation of the plate is what it is; it's all epoxied up. But I can rotate the corrector to match the mirror. The only marking on the mirror is what you see in the picture. Celestron incidentally said the numbers are not the same thing as the orientation mark but the numbers are the only mark on the plate; that, and a very slight side mark. (which corresponds to the numbers that you see in the picture). thanks for your help, Greg N

Pursuant to my other post, which has a Celestron corrector showing no reflection with a flash picture (C14 with Starbright coatings), I found this additional picture of Minox binoculars. These are also photographed at an angle, and you can also see that the only evidence of the flash is from the internal metal, not the objective.

My conclusion is that the "flash test at an angle" is something that most companies-who-know-the-optics-biz can pass, on a wide variety of optics. I suspect that multi-hour exposures with ccd cameras is where AP optics show their sharpness, color correction, and general top notch execution. It is of course possible that there is a certain threshold of execution that the angle/flash photo test provides, and that Minox, Celestron, and AP all pass that threshold. Possibly there are much lower end optics that would not pass the test. I have a c8 which has no coating decal on it so maybe I'll try with that. For me this is actually getting rather beyond the AP-is-great issue into a more interesting topic, which is whether this very simple to perform test, camera-flash-at-angle, actually tells us anything useful. I'll try to post my no-coating c8 (at least it says there is no coating sticker) later. The previously posted C14, I repeat, had Starbright. The Minox like all upper-half-of-the-market binooculars has something like two dozen multicoatings.
