Fits AT1010 w/screw on dew shield for sure, will fit others with 106mm ID. Very pleasing views. I'm selling as I'm also selling the scope (AD 241055). If same person buys scope then I'll knock $5 off for shipping.
From their website....
Type 2 Plus: Made with high quality hand select glass coated with our exclusive Solar II Plus. The most durable glass filter on the market. Transmission is 1/1,000th of 1% (Optical Density 5). Great for both visual and photographic use. Solar image is yellow-orange. Guaranteed fifteen years.
Things to consider...
There is a small blemish on the outside of the glass (I blew up one photo so that you can see it, photo shows the blemish and its reflection not two blemishes) that doesn't affect performance (that I can tell).
Cost $69+ shipping new, $45 shipped CONUS FedEx/UPS Ground w/tracking number. Paypal preferred (no fee), but MO or Postal MO cool too. Check my feedback.
I will be out of town until Thursday on business. I will have access to email, but will not be able to ship until then. Thanks for looking and call or email if you have any questions.
