Test Result of Heavy Light Pollution : Astropical

Astropical

This site is for Astronomy Studies in the Tropics. I'm based in East Pattaya, Thailand, 12.934N, 100.918E, between the sun's northern limit and the Equator. The big advantage of this location is that you can observe both northern and some southern stars at the same time. And it's never cold... lol. I hope to introduce you to the unique celestial opportunities available from this area. Enjoy your observations!! Taro Seki Astropical.uk

Test Result of Heavy Light Pollution

Optolong L-Pro is winner

Last night, I tested the light pollution filter to see how much light pollution can be cut.
Tested in a terrible party light, clearly over 9 in the Bortle Class.
It was the best environment for testing because I couldn't even see Mars.
However, this test is only a test against light pollution, not atmospheric pollution.
People who are suffering from atmospheric pollution are familiar with it, but that cannot be prevented very much.

昨晩光害をどのくらいカットできるのか光害フィルターのテストを行った。
Bortle Classで明らかに9を超える酷い状態のパーティー・ライトの中でのテスト。
火星すら見えない状況の中であったのでテストには最高の環境であった。
ただしこのテストはあくまでも光害に対するテストでしかなく、大気の公害では無い。
大気の公害に悩まれてる方も身近にもおられるが、あれはとても防げない難題だと思う。
ということで

Optolong L-Pro君の勝ち。
