- light pollution
I took a chance on buying this filter to try to combat the bottle 8 light pollution in my area. So far, it has not disappoints me yet. Figuring out the optimum exposure time and gain for it still an uphill challenge, but soon will conquer.
I've always done narrowband with a mono cam, so at first I was a bit skeptical. I decided to jump on the hype train and see what it was all about. The hype is real my astro friends! I have taken images with this filter using just a normal dslr and i am just amazed how I can do narrowband Astrophotography with just a DSLR. Now I haven't used an osc yet but I believe it would be even better. This filter is perfect for those wanting to image in their backyard with a DSLR or color camera. We've all been there before; it's clear at the dark site but its hours away and something came up where you couldn't spot the gas for the trip. You feel defeated and sad that you can't image that night. But now you have not to worry of those moments as now you'll have a filter to help you at home even in the most severe light polluted skies. This filter is well worth the price and costs much less than getting the separate halpha, hbeta and oiii filters. It also will cost much less in the long run than all those trips to dark sites in gas and save you wear and tear on your vehicle. I'm a believer! Tell em Kurt sent ya!
