Description

Probably my last go at anything on the barn door tracker. Once I have another clear night I should have better gear. But I wanted to give it a shot and see what the CLS filter impact was. My prior attempt had the CLS used, this does not. A lot less blue, but not much more on color. There is more detail picked up in the core. There's a lot of background noise too. Combination of calibration frame practices and total exposure time at fault I assume. Always something to learn!
