That would be my conclusion. So, I guess the Roxsen adapter is cheap as well as inexpensive ...bwa

Here is an image I took earlier for the CA experiment with the RAW file converted to mono in RawTherapee. One thing I see from this is that the original CA was exasperated with the demosaicing done by Lightroom. The edges look different here.

Okay, guys! We’re getting off-topic here. NOT that this monochrome-conversion matter doesn’t interest me, but perhaps one of you would deign to rekindle it in a new Topic with a suitable header? 🤔I've actually been using FastRawViewer and Monochrome2DNG for about a year for other preprocessing so have a pretty good idea it will accept the files off the a6000(m) without debayering them. Yup, you don't want to debayer a monochrome image and lose all the resolution gain!!
Monochrome Imaging Services did the conversion.

Monochrome Imaging Services did the conversion.

Looking forward to seeing some results from this camera! Would like to see an image with stars and the original RAW file to see how the details look.
I'll be using the A6000(m) in much the same manner I use a normal mono astro-camera, i.e.: with LRGB, Ha, Hb, Oiii and Sii filters. It's the first time I'll be able have the ease of use of a DSLR/MILC camera and the spectrum response of a mono astro-camera. It's a whole new chapter in my astrophotography trip!
I'll be interesting to see how imaging with the A6000(m) compares with my QHY 163M. The QHY 163M is cooled but both have almost the same photosite size; 3.92 vs. 3.8 microns, respectively. And cooling isn't all that critical when one has eight months of winter weather per year.
The a6000(m) will also get considerable use for B&W photography as well as for normal Infrared photography with IR Pass filters.
Stay safe and healthy!

Thank you for explicating. Initially, I thought that your Ha response was either a typographical error or two people ceaselessly competing by exclaiming "hah"s.
Astrophotography almost has its own language of terms and acronyms... bwa

Agreed, but we may have already discussed the topic to an end, leaving you probably only one viable option; Metabones.

I concur, in general, though certainly there are exceptions, such as applying cellophane tape to frosted glass. But let’s suppose you’re right for the moment. Just how much is IQ degraded? Obviously, it depends on the quality of the wspeed booster. Would not some objective MTF analysis be useful for determining this?
Eyeballing will be the final word !
Has it occurred to you that deploying a TS lens on a focal reducer creates a conflict of optical axise ? When you shift the TS lens you now have two separate axise ... one thru the TS and a parallel axis thru the reducing lens. IOW the total combined system is seriously decentered. At least both axise are parallel ... until you engage the tilt !
FWIW I have used a shift 35 on a reducer. Stopped down it was useful ... but not for pixlpeepers !!!!
For a TS lens on my a6000 I put an old 17mm FF lens on a Nikon to Sony TS adapter. That combo isn’t very ergonomic but at least there’s always just one optical axis and it’s not asked to bend in the middle when tilting ... plus no extra lens elements ... and, you can put your UV lens on the adapter:-)

Curious about whether you got a speed booster after this thread ended?
