I thought that I might have some fun comparing the performance of some UV/IR Cut filters I have.

They are an Optalong, a Player One and a ZWO (left to right).

The test subject was chosen at random. It was NGC346 in the SMC.

Here are 3 cuts from the centers of these 3 images processed in PS5 and only treated with a touch of levels to tone down the green to something more palatable to the eye.

Each is a stack of between 24 and 34 subs of 180 seconds each on an ASI533MC Pro at -10C.

The PlayerOne (which is touted as "AntiHalo") or some such seems to do quite well. The Optalong is probably the better of the 3. The ZWO falls well short.

I'd be interested to hear what you think.
