The Flying Jaw Nebula In Vela (NGC2899)
A planetary nebula in the constellation Vela
Drawn in by its bizarre name, "Flying Jaw," I recently found a spot in the low southern sky where I can photograph it for only an hour and a half a day, and decided to give it a try.
As expected, the atmosphere was thick, and I realized I needed AO equipment. At 1'30", it was a small target, and even with 2.0x magnification using Drizzle, I couldn't see any internal details, making me wish I had a larger aperture telescope.
It's become a target that generates equipment stress.
ほ座にある惑星状星雲
「空飛ぶあご」というなんとも奇妙な名前に釣られて、最近1日に1時間半だけ撮影できるポジションを見つけた南天の低い空のターゲトに挑戦してみた。
流石に大気が厚くAO機材が欲しいと思った。サイズも1'30"と久々に小さい対象で、Drizzleで2.0倍に拡大したが 内部のディテイルなんかも丸で出せずにもっと大口径の望遠鏡が欲しいと思った。
機材ストレスを生み出すターゲットになってしまった。
