Horse Head Nebula (馬頭星雲) LDN1730

I want to bring out the characteristic beard of this nebula, but this resolution is not good.
Next time, let's try Unlock at 294MM.
The main captures were Ha and Oiii, but I didn't use Oiii in this image after all. I think it would have been better to let Ha be exposed by that amount.
challenge again! !!

この星雲の特徴的な鬚をだしたいが、今回の解像度ではダメだな。
次回は294MMのUnlockでやってみようかな。
メインのキャプチャはHaとOiiiだったが、結局この画像ではOiiiは使わず。その分Haの露出にまわせば良かった気がする。
再挑戦!!
