The Inside Bubble Nebula (バブル星雲) NGC 7635) (2000mm+1340mm)

I added another 2000mm for 200 minutes and stacked it with the 1340mm I shot last year.
The inside of the bubble is now sharp, and it looks good.
There is still plenty of gas in the background and surrounding areas, but since the target this time was a structure inside a bubble, I tried to keep the exposure quite subdued.

再度2000mmを200分追加して昨年撮影した1340mmを合わせてStackして見た。
バブルの中もシャープになり、良い感じになってきた。
背景や周辺のガスもまだたっぷり残っているが、今回のTargetはバブルの中の構造なのでかなり抑え気味にして見た。
