All units come with an appropriate 1.25" nosepiece to match your unit.
DSI Pro and DSI Pro II models come with two 1.25" nosepieces - one for the Stiletto and one to substitute the original flangeless Meade nosepiece.
If you are using a 616 CFW, you will also need an extension tube for the nosepiece. Please click on More Product Information below. Also check out our Autoguider Focusers if you have a Meade LPI or DSI.
