I had a brief time to try my new toy; an ST-8300 with filter wheel.  I took the following sequence: LRGB, L 10 images at 3 minute sub frame, RGB was 15 images at 2 minutes.  I did not do a bias flat or dark (just tested the system).  Aligned each channel of RGB and then Luminance. Then went to Photoshop and created a RGB in Channels then layered the Lum on top.  Did Unsharp Mask and then saved.
