Sombrero Galaxy + M46 open Cluster - Both With 16" + ASI 185

xs_man

Two new pictures taken with the ASI 185 color cooled camera.

Cooling was set to -25°C.

Both with a 16" Newtonian.

5 sec exposure for M104 without filter. So I remove color information

(completly modified by Infrared part of incoming light)

Near 1150 x 5 sec subs (15 march 2016)

M46 and his planetary nebula were captured last 12 and 14 March 2016 :

3900 x 1 sec + 580 darks plus 1700 x 1.5 sec + 780 darks

Ir/UV cut filter

Best.

Hi Albéric,

that's stunning !

P.S. please, tell me, what are your Dark setting to mitigate amp-glow?

did you use Firecapture and AS!2?

cheers

I may have missed it, but what focal ratio did you shoot at?

Also, any chance you could post single subs? I am very interested.

Thanks,

Many thanks for your comments. ;)

No, I did not use AS2 for registration. As far as I remember, I use

Registax.

For the settings, here I don't take care of using the ASCOM setup.

I use Firecapture, as I do for planetary use. Short exposure so high gain.

With IMX 185, the amp glow is sensible so it's very important to have

cooling and keep the temperature of the sensor to a fixed value during

the night.

Here is a raw image of M104 :
