Askar M48 / M54 Backfocus Adjuster
I am pleasantly surprised by the quality of this backfocus adjuster. It has detents at fine intervals and takes the headache away of the need to add or taking away shims when adding or removing filters or just fine tuning backfocus. Very good quality for sure.
I needed a very precise spacing for my Starizona reducer, and I had trouble reaching it with standard spacers. Moreover, if the backfocus changes with the filters I can now quickly make the adjustment with the Askar. I was first afraid such a "mobile" component would introduce a tilt in the optical train but according to Astap my tilt is practically zero.
