Lots of manufacturers now are offering an Astro version.

Interesting, thanks for sharing Greg.

It'd be extra interesting if Fuji posts the band pass before and after

Thx Greg.
I wonder if it will allow you to 'Turn Off' the IR and limit the spectrum to visual only.
Greg, how do you find using the EVF's agains optical for fine focus?

the x-t1 evf is excellent

some of the Fuji lenses deliver bad hot spots for IR, the 14/2.8 seems fine & strangle the 18-136mm travel zoom is also good. the excellent kit lens 18-55/2.8-4 seems bad

I wonder who else Fuji expect to sell this too -the astro aps-c market I would think is small -when you can get a 6d, 800d, A7s

Thx Daniel.
Good question too. Canon discontinued the 20DA fairly quickly, and only did the 60DA, I'm sure, because the internet has shown just how many people are into astro things, yet I have to wonder how many they have sold.
Given the Nikon astro camera, and the others you mentioned, you'd think it too big a business risk to release a limited use camera like this.
Still. I look forward to the reviews.

EVFs are awesome in nighttime for focusing also for daytime. Focus peaking, magnified view and the WYSIWYG make an evf very attractive. I love em. Some don't.

Sorry for the off topic question but does the focus peaking function work on stars when out in the dark?

Hi, yes it does, sort of. Spent the past two nights mucking with it through an 18mm f2 prime doing a series of simple quick tripod exposures.

At peak focus more stars will resolve, either side they fade out, say an 8th of a turn perhaps. It's enough to quickly do a few shots and check and tweak focus. Over exposing helps reach critical focus during the focus assist function, as the stars will be a little brighter, then switch back to your real exposure settings to drop the shutter.

Funnily enough here is an uncropped more or less straight out of a little X-M1 from tonight, same x-trans sensor and so-on as the X-T1. I don't photoshop my pics and it's probably obvious, oh well..

Does quite a nice job except for the visible coma on the left side, just one of the troubles of imaging at F/2!

No you wouldn't be able to turn it off as its lacking a few filters in front of the sensor that digital cameras have. IR filter mainly. You could add one back in front of the sensor or on the lens. Xnite CC1 filter was one such filter that kind of brought it back to normal.

Looks good mate, thanks for that
