(540mm)A middle-South Part of California Nebula (カリフォルニア星雲Zoon-Up)NGC1499 : 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

A middle-South Part of California Nebula (カリフォルニア星雲Zoon-Up)NGC1499

I was planning to edit it in SHO, but when I saw my UK friend Keith posted a straight red California Nebula, I thought that red was good, so I summarized it in HSO.

I intended to shoot at 11m in Lock Mode of 294, but I shot at 44mm in Unlock Mode. As a result, Gain was insufficient. It is around this time that I feel aging.

SHOで編集するつもりだったが、UKの友人Keithさんがストレートな真っ赤なカリフォルニア星雲を投稿されたのを見て、やっぱ赤がいいなと思いHSOでまとめてみた。

294のLock Modeの11mで撮影したつもりが、Unlock Modeの44mmで撮影してしまった。その影響でGai不足な結果になってしまった。老化をひしひし感じる今日この頃である。
