New role for my T6s. HA solar!

It turns out the T6s are excellent for solar. Not that surprising given their being very sharp with great contrast. The warmer tone seems to make surface detail stand out nicely with 3D filaments. Proms are very sharp and fine structure shows well. When they had the stock eyecups it was hard to maintain position to put it mildly and as to blocking light really bad. However with the 2" ones it was pretty near ideal. It's are easy to maintain eye position and shield them and they're not prone to fog when it's humid. Being light they're usable with my tail heavy Lunt 60 single etalon on a WO EZTouch that has axis lock issues. I like the T6's short ER for solar. The power range using with the 7mm, 9mm and 11mm Fls plus the barlows is near perfect. With my scope the sweet spot is 60%-70% of the FOV wether it's 50* or 82* so the T6's FOV makes for a big sweet spot. It just so happens as this post is being written I'm using the 11 T6 with the 2X TV barlow for 90X-100X with lots of surface activity and very good conditions. It's quite the sight with the active areas having a glowing ember quality and a darkish orange surface. So will you be seeing any of my T6s in CNC? Not likely! David

That said, I compared pairs of 13mm T6s to pairs of ES 14mm and 11mm 82 N2s and preferred the 13mm T6s.

Actually, 24mm Pans (25x) put up the overall nicest view of the sun today, though a significantly smaller presentation.

public servive announcement for any lurkers with PST's. Some of the T6 will not reach focus in some PSTs due to needing more in-focus, just out of range of the PST's limited range focuser. I forgot which ones exactly, but test before you commit to one.
Wow... That would be surprising to me because all the Explore Scientific 82 N2 eyepieces I've tried have required significantly more inward focus travel than the T6s (and the 12mm AT Paradigm so much that it was unusable in my h-alpha rig without modding something).

PST does not have much of a focusing mechanism, being internal and all.
