The Little Cocoon Nebula (小さな繭星雲) SH2-82

Season Overtime 3

For the first time in my fourth year, I was able to shoot the stars in July. The weather has changed a lot this year, and in February, when I could shoot every day, I could only shoot a few days this year. Instead, it may be Lucky to be able to shoot summer celestial bodies in July.
Compared to Cocoon Nebula (IC5146) in the north, it looks almost like the zenith from Thailand. Littele Cocoon Nebula. The size is about 3/5 of that of Coccon.
Similar to Trifid (M20).
The star frame was exposed with a blow band F / 1.9 180Secs for 1 hour, causing the star light to become saturated. It might have been better for about an hour at 60Secs.
I wanted to make it feel more buried in the stars, but I gave up because the bright stars became terrible.

北にあるCocoon Nebula(IC5146)に比べタイからはほぼ天頂近くに見えるLittele Cocoon Nebula.大きさはCocconに比べ3/5程度のサイズである。
星のフレームをブローバンドのF/1.9 180Secsで1時間露出したため、星の光が飽和気味になってしまった。60Secsで1時間くらいの方が良かったかもしれない。
