SVBONY H-Alpha 7nm 2" & Optolong 2"H-Alpha 7nm

Good Day All

I need some advice / guidance with the following two H-Alpha Filters:

SVBONY H-Alpha 7nm 2" & Optolong 2"H-Alpha 7nm

They are offered at a much better price than the other more well known brands, does anyone have first hand experience or tested either of them ?

At the exchange rate of R 18.90 to the Pound and R 14.40 to the $ every one counts at this stage.

Thanks
Andre

Hi Andre, I would be very suspect in buying a low priced narrow band filter. Over time it has shown that low cost filters have issues such as halos, or leakage from other bands. I would save further and if one can't afford Astrodon (I can't) then my chice would be either Baader or Astronomik.

You may have already seen this thread on CN regarding a test of the Optolong Ha filter.

Thank you for the reply , It seems that I shall have to save some more before buying the H-Alpha filter , pity unfortunately it is now impossible to image with my new neighbors insisting on leaving an unprotected 100 watt bulb burning all night about 15m from my pier.

That is too bad. Yes, neighbors do suck at times.

I've used Optilongs, satronimics, baaders, and a few other spin offs, I sold them all for Astrodons. If your fighting light pollution the Astrodons were the only ones that did the best job

Have you tried asking your neighbor to do something with the light?

I have a neighbor that for some reason thinks they need to light the side of my house!!! Unfortunately, they are not reasonable people...I keep thinking that a BB gun may resolve my issue :smile111:

Don't laugh, Entergy came out and put this huge halogen light bulb on the land behind my house which is in the path of the North where I primarily image, and there was know reason to do it. It's in the middle of a pecan grove of trees and there is nothing back there. The light has been out for 6 years and I could not understand why they did it.

I hit is with a pellet gun and hopefully will get another six years. LOL

If your using pixinsight you can at least pull a LUM channel out of your image (very first thing you do) and use that to shrink your stars and add some detail.

Good luck.
