Just checking out my QHY 168C with the Optolong L-enhance filter last night. It was really windy and I needed to check out the camera as its just back from the repair from the lightning strike last April. You can see it is working great. With all the wind and dust last night this would have not been possible without this special filter. It is great for imaging when you are in a light polluted area or shooting when the moon is visible.
Used Sharp Cap 4.1 to stack 22 subs at 2 minutes each. There was a little jitter due to winds up to 25mpy last night. But the mount held pretty well.
