To be pratical, the only way I think one will decide on such an acquisition will be the financial support he might have.

 

Built and optical qualities and the final use are not questionable, neither is the strong will to have one of these binoculars.

 

The people with the money to spend will buy it, the others (like me) will buy something much cheaper and do the best they can with whatever they might get for their (small or large) amount of money.

As always....YMMV, different strokes, etc.

 

My equation is heavily influenced by the noticeable decline in really good observing nights over the last 5 years in my region.....

 

Lots of really great and expensive equipment sitting idle too much of the time.

YMMV

 

In the late 1990s I got a pair of Miyauchi FL 100mms

In the early 2000s I got a pair of Fujinon MT 150mms

Comparing the two, the Miyas were a little sharper, better contrast;

the Fujis has a little better reach, but not a whole lot of difference

except 25# vs 120# for the set ups

I kept the 100s, sold the 150s

perhaps with darker skies.................question.gif

 

YMMV   edj

That's approximately a one magnitude difference in light gathering power. I know what this means for point sources like stars, but I wonder the exact effect it has on extended objects like nebula and galaxies?

I had to save for a few months to get my 120’s.  I got them. I enjoy all my binos (I rotate them in my observing sessions).

 

I just want more clear skies! 2018 has been a very frustrating year for seeing.

"P.S. I am a lawyer ..." That was a funny post. lol.gif

 

 

Price divided by the number of total hours (price/hours of use) might be a good start calculation to establish hourly rate and amortization period.

 

Example 1:

I have read 7500$ for those APM binoculars and I will establish 1$ per hour as a reasonable cost for observation. One will need to use those binoculars 7500 hours to consider them to be paid, roughly 20 years at 1 hour per day/night of use.

 

Example 2:

Using the same basics from above, if you use it 2 hours per day/night, this will come as 3750 sessions of 2 hours each, wich comes to slightly more than 10 years to effectively amortize the original purchase price.

 

Example 3:

The example 2 above comes with a monthly usage of 60 hours. Eventually, you may not be able to use the binoculars every night. Let us say you only use them 20 hours a month. In this latter case, you have to triple the amortization time, from 10 to 30 years.

 

From the original value you might subtract the value you think they might be worth in the near future, if reselled. This is not easy to establish, (because one will never know when he will sell it, neither the condition it will be, neither the commercial value it might have in the future), but a minimum value can be established. I would say 2000$ will be the minimum price for it. So, you may subtract 2000$ from the initial 7500$ and do the calculation again.

 

 

Hourly rate is always a good way of having the notion of the pratical cost of some equipment acquisition and the amortization in time.

Don't forget to factor in the much more expensive mount needed for such a large pair of binos.

A decision for each of us--how much is that one extra magnitude worth

-in cost

-in mass of optics

Although I am still a little tempted by the 150's, after a recent session with my friends ServoCat/Nexus driven 18" f4.5 Ultralight Dobson, I am now steering away from the 150's. I still love my binoculars but for the same money and less weight, the number of potential objects with a big Dobson is much greater.

I imagine it would be a great addition to a home observatory at a dark sky site alongside your scope. It's practical if you have the finances and are trying to build the best observatory that you can. And there are quite a few of those people here on cloudynights. In an observatory setting, that's where it's really going to shine and it would look pretty darn impressive.

 

When you weren't viewing it would be fun just to look at it.... cool.gif cool.gif

Pretty much just as easy to use too. Only difference is a smaller FoV.

It's a beauty. Looks like the rail has some various mounting options on it. Like the tripod and fork mount. If you can handle the weight, it certainly looks like it could be handled.

 

Just so expensive..........

After you buy one?  wink.gif  You could put a tripod dolly on it very easily and wheel that thing out of the garage. Looks much more easier than the Fuji's. Not to mention 2" ep's.

Like I said before, too heavy.  I saw the pictures - too beastly, and not for me.  At that point a decent Dob would be better.

I would say that with experience comes wisdom.  I think I have a few years on Mr. Bill, but I have a strong desire to be able to say "been there, done that" too, in regards to experiencing such an instrument.

"been there, done that" is much better than

"never been there, always wished I had"

  question.gif

150s is not a practical move, 

100s can see almost as much, 

a big dob can see a lot more detail,

the money can be better spent many, many ways;

but having that big bino under the dark sky

 

is wonderful ,    said the moth to the flame

I like the body design of the new APM150's. It looks as compact as you can make a pair of 6" refractors.

The 45 degree version is only 3" longer than my Tak 102 binoscope. Will be a nice pairing with the 2" 30mm UFF.

 

I'm waiting on the SD model and will post a review of their performance compared to the 102's and the APM 120. 

I recently bought the TTS 160 to make use of the Taks's high power abilities and it should also be perfect match to the 150.

I'll be looking forward to your review and comparison.  This will be fascinating stuff!
