Description

Hello all,

After a month of clouds I picked up the Crescent Nebula as my next target. I really wanted to give it a go and was secretly hoping to see the Soap Bubble in the image. I imaged the same target last year with my C6 upgraded with a hyperstar (but no narrowband filter). I took 7 hours of data back then only to find out that I hardly see the Crescent Nebula. I was quite disappointed

Now initially I stacked the images after the first night - 4 hours only and started to scream from joy when I saw the contours of the Soap Bubble. Then I imaged another night and this is the result of my session on this night sky object.

Imaging with the ASI2600 MC-Pro is fun tho:

- the star aligned and debayered images are only 92 gigabytes XD

- however I managed to remove the noise from the image without the help of TopazDenoise so I guess the 2600 is quite sensitive.

- I managed to capture the soap bubble from the city at full moon with a color camera!!!

In addition I love my RASA!!!

I wish for clear skies to all as I am off to the next target.
