Van Slyke Versa Port Slider2 Combined Flip Mirror/Off Axis Guider etc
Van Slyke Slider 2 off axis guider/diagonal/flip mirror
I only used this a couple of times and now guide with a seperate guidescope so it seems a shame to have it sat on a shelf doing nothing.

It acts as a 2 inch diagonal, a flip mirror, an off axis guider and a 2"filter holder

I am sure you will know these were a VERY expensive item when they came out ...about $500!, and have a well respected reputation so 90 is a bargain (no offers)

They are hand made and Paul Van Slyke signs each one himself.(see pic)

I am pretty sure they are no longer in production as his machine shop sadly burnt down.

You will know all about them no doubt but if not this is a link to a review of one here

http://www.observatory.org/stestr.htm

You will notice in the pics (pointed at by pen) that I have fitted 2 pieces of 'springy' plastic that keeps one axis of the small take off mirror adjustment in tension...originally it was a piece of spring steel which broke but the plastic seems to work fine...you screw in a hand screw which pushes the take off mirror against the tension of the 'leaf' spring...like I say the strips of plastic (cut from a credit card) work fine but...a new piece of spring steel could easily be fitted by anyone with some engineering skills.

The take off mirror gives loads of adjustment in TWO axises...the lever you see in the pics is for the other axis

Both mirrors (the small take off one and the large slider) are in excellent condition.

I have repainted the inside of this assembly with matt black paint

The unit is is good condition and comes with a 1.25 inch extension piece and another threaded adaptor...see pics.

Will post to UK mainland only via signed for and tracked post...it weighs 2 lb and have just checked the postage online with Royal Mail and a small parcel of this weight insured for 100 and signed for and tracked is 11...I will pack it well with lots of foam/bubblewrap

Due to problems I have had in the past with paypal I refuse to use them when I sell items...I realise this will put off some buyers but so be it.

I have bought and sold many items.. 70 ish.. over the 12 years I have been on astro ads as you can check in my profile.

I can accept cheque (cleared) cash, postal order, and bank transfer.

I am in Thornton Cleveleys Lancs (between Blackpool and Fleetwood) if you want to collect....cash on collection only
Price: 90
