Picked an 8mm Baader Hyperion yesterday....... only to find out I have a trade for a 7mm Pentax XW for my meade 14mm UWA, which now makes the 8mm Baader hyperion redundant. I called my shop where I got the 8mm Hyperion and asked if i could send the 8mm back for a 13mm Hyperion and he said "yes!!!"......here is the 8mm Hyperion just for you to see.
I can't wait to get a hold of the 7mm Pentax XW...I had one before and know what it will deliver: top-knotch images!!!
