Heya,
Woke up to a cloudy sky but had some sucker holes. The AR's are pretty large, so I had to attempt some mosaics to be able to frame them up. I did two at different times, and you can see the differences in AR2725, it's a feisty little AR and has some activity going on spitting some filaments around in a short period of time. Some large proms are still on the limb, but I had a hard time with them through the clouds which really robbed the transparency and killed the exposure, but they're still represented.
Celestron 150mm F8 Refractor + Daystar 150mm ERF + Baader 50mm UV/IR Block Filter + Quark + ASI174MM
Coronado PST + 1.5x Barlow + ASI174MM
