I bought two UltraBlocks brand new from Orion (right before Hurricane Charley) because I couldn't find any sellers here on Astromart to the ad's I was posting. I was going to use them with my 50mm Canon IS Binoculars but found they cut way too much light (due to the small 50mm aperture of the binoculars) to be practical. As such, I am selling these after trying them ONE time the night I discovered this fact. Asking $70 each and I will ship USPS 2-3 Priority. Each has box and original papers filter profile from Orion. Save almost $40 over buying one of these new from Orion yourself and getting regular old ground shipping. My loss is your gain!
