Messier 8 in HaRGB

Post by cataclysm »

Typical imaging session is a lengthy & lonely affair, but this time round, I got the good company of Gavin ( aka Starfinder ). This was taken on 18 June, and M8 is pretty high up nearing midnight at this time of the year. We were dodging clouds initially, but the sky cleared up once passed midnight, and it stayed clear till 3 am. All in all, managed to gather a total of 2 hours of image data, spliting between 1 hour each on H-alpha and RGB. The imaging scope is Tak Baby Q and the camera is Meade DSI III pro.

A very nice image Kelvin! A lot of fine detail and curtains of texture.

I think your setup is brilliant, esp the cooling and dehumidifying systems for the imager! It was the first time I saw a Bahtinov mask at work too.

Best wishes for more great images.

Hi, thanks Vincent, I am using the Losmandy GM8.
Another great pic from light polluted Singapore.
For objects that are strong emitter of HII, we stands a fair chance to capture them in good details with narrowband filters in light polluted sky like ours. Below is a total of 50 minutes worth of exposures with H-alpha filter at 5 & 8 minutes sub-exposure. The RGB filtered images will be pale in comparison in term of details.

Nice pictures! I still think the color version shows more details... especially at the 11 o'clock position near the bright star... the gradient is more apparent in the color version.
