Optolong 2" L-Pro Light Pollution Filter

I like the Optolong L-enHance filter a lot, but it is pretty narrow in the Ha and OIII, so sometimes star colors are hard to preserve. This L-Pro filter is a decent compromise for my Bortle 7 suburban skies. I get good contrast in my images and fairly natural colors as well. I think this is a good filter for broadband targets like galaxies, star clusters and some comets. L-enHance is probably better for emission nebula like M57, NGC7000 and the Helix.

The filter works well from my Bortle 6 backyard as the attached picture of the Andromeda Galaxy shows. I would highly recommend this filter for imaging with small refractors like the Radian Raptor 61 or William Optics RedCat 71.

I purchased the 2 inch. Cuts out light pollution, sure. Also cuts out color and visible light. When using I notice my star field looks a bit like a tunnel. Mostly noticeable before you crop your photos. I used the L Pro for a bit but didn’t do as well of a job on the light pollution but let’s you capture more natural colors.

I use this filter in all my imaging sessions other than those requiring specialized filters, like H alpha. It produces a slight bluish hue that I like. Seems to be working perfectly well in my suburban environment.

This is a very high quality optic filter. I use it in the filter box on my Zwo533mc pro camera for my RASA8 at f2 imaging setup. It just works great. I shoot from my back patio in bortle 8-9 washed out sky .

Filter does exactly what it’s advertised, pulls out all the color in broadband targets from light polluted skies

Great light pollution filter. I’ve got Bortle 7/8 skies where I live and this filter cuts the light pollution out which enables me to get the long exposures I need to image deep sky objects.

I like that it filters out the light pollution and still provides natural colors of the objects in the night sky.

Does what it claims to do happy with purchase
