Actually, ILya is an optical physicist who does engineering for fun...

I guess I would be the opposite to that coin. A mechanical engineer that does chemistry for fun.
But LR shooting and amateur astronomy / imaging are a close second.

This is quite interesting, and I am always open to listen when others with more knowledge decide to speak.
Care to share anything about the chemical compositions of ED glass VS CaFl crystal. And how the synthetic fluorite crystals are grown? I have always wondered how they did that. I don't believe that is proprietary in any way.

Ilya does not design scopes for a living.  The systems he is involved with are somewhat more complex.  However, I'll let him tell you what he wishes to of his occupation.

So just what area of chemistry do you do for fun?

At the moment I run the North American operations of a company that builds optical test equipment, remote sensing instrumentation, hyperspectral imaging systems and some other more customized things.

The optical systems we build have to outperform the devices that are tested on them by a significant enough margin to make their contribution to the resulting data effectively negligible.

In the past, I have worked on space based radiometers and imagers, DSLR and broadcast camera imaging sensors, ICBM launch detection systems, soldier mounted thermal imaging devices and a few other things here and there.

My original education is in applied physics with primary focus on electro-optics and optoelectronics.  That is what I did at Caltech, but most of my career has been in electro-optics and imaging (almost by accident).

As far as riflescopes go, your persistent comparison with fancy Takahashi telescopes is irrelevant.  The Premier riflescope you have mentioned has one of the best imaging systems available in a conventional riflescope and it cost somewhere between $3k and $4k.  Tangent Theta which uses the same basic optics, but re-worked mechanics is about $4200 for the 5-25x56.

If they were deigning it for a higher price range, perhaps they would be different.

Conversely, if Takahashi were to design their telescope to be mounted on a weapon system, the ruggedization would double the price and adding a properly corrected erector system would likely add another 50%

Making it a targeting system would add yet more.

I was thinking the same thing, if TAK were to build a riflescope OMG damn it would be sweet.  And I agree Premier/TT has some of the best optics available to date. Put simply, their glass is friggin gorgeous..  That's why I own two Heritage 5-25x56 and a light tactical 3-15. The new Tangent Theta at $4200 seems a little steep but such is the nature of where high end is heading.
Chemistry?? I like energetic materials and dabble a little in pharmacology..Wink

I got to say that's a pretty damn impressive resume there Ilya.

I resemble that remark.  They lost me at triplet.

God bless The Marines! The old Marine parable is awesome...

You can put 4 Marines in a locked padded room with a bowling ball. Then come back in 5 minutes and find the bowling ball broke and on fire and non of the Marines know what happened.
I also have seen the same parable, but the bowling ball is preggers, lost, or just broke.

Does that mean you use recreational drugs?

Yes a riflescope does need to withstand extreme g forces but still glass to metal interfaces are common.  Lenses are still held in with a threaded lock ring just like a camera.  And although the designs vary in how the erector tubes are adjusted for targeting, it's still composed of screws and springs whether it's a 5k S&B or a $50 BSA.

I used to play around with astrophotography, I used a DSLR and a Meade AR-6 Achromatic Refractor. I'd probably still do it if I owned a Takahashi and a good GEM. I found the experience frustrating. There was "slop" in the GEM i owned, and I had a hard time getting precise focusing through the tiny viewfinder of a DSLR. That was before I had cataract surgery done though. I did get some spectacular pictures of the moon. If i remember right, i used my Nikon D200, 2X tele converter,1200 mm scope. That gives you roughly 60X when you factor in the plus 50% using a Nikon CCD. I know this is off topic.

A critic will notice the oval shaped stars, this is because of the mount not tracking at the same speed as earths rotation. Just guessing, but this is probably a 5-10 minute exposure of the Ring Nebula.
