Vela SNR Deep in 3nm NII

I was aimaing for twelve subs but cloud came in after collecting five frames.

Exposures 5x32 minutes. Both the large images are x1.5 the native pixel size of the PL16803 camera.


Large image FoV 3.5x3.5 degrees. 13 MB.

Inverted version 13MB.

I will add more frames when weather permits. There is already very good detail of very faint features. More subs will further improve the image.

The RH200 will work quite well with a PL16803. The camera just needs to be perfectly orthogonal to the optic axis of the RH200.
