Very challenging session. I used my Celestron 150 masked (not my best Cak scope) and had haze from the Canadian wildfires. It was a test session for my new EO 394/10
Celestron CR 150/1200 masked to 60
ZWO 290
Cak module: Chroma .1 + Alluxa .1
blocking Chroma (surface) or EO 394/10 (proms)
I tried to TS and QS with my lunt Cak etalons but didn't make a huge difference on the surface
These really are excellent Alan. I found no real improvement triple or quad stacking in CAK, just exposure time got a lot larger!

I have a Chroma .1 + Alluxa .1 filter in a sky bender. I purchased Apollos old set up so he could fund other projects
