Beautiful workmanship and versatile function make this the astrophotography weapon of choice. It is built like the proverbial BSS and as opposed to the ordinary flip mirror, “to obtain the shortest possible profile, the diagonal mirror slides to the side instead of flipping down.” On my unit Serial #077, the slide is underneath, rather than on the side. It has the 2" barrel nose, for use in 2" format slip-fit focusers, and slips in just like a diagonal. It has the built in zero profile 2” filter slot with the quick release spring plate to hold your 2" filter securely in it's cradle, a spring-loaded ejection knob (bottom) to eject your filter into your hand with a single [one-handed] motion, and a light blocking insert ring (shown in my picture sticking up) to block stray light from entering when you're not using your filter slot. Recent change of directions makes this unnecessary, and funds need to be diverted to other astro projects.

Purchased recently on Astromart from a rated member, I have not had a chance to use this, but operates smoothly and the mirror looks in excellent condition.
The current price on the Slider 2 is $595. I’m asking $325 for mine, shipped UPS insured CONUS. Paypal accepted with 3% add, or cashiers check or money order prior to shipment.
Thanks for looking
