RH200 Test Images

Had a bit of clear sky so I collected some data with the wood camera restraint. THe adjustable metal one is being made as we speak.

This first image is a region just to the right of Alpha Cent. 10x8 min exposures in 3nm NII. x1.5 times native pixel size. 13 MB

Note how the stars are fairly good to the corners The adjustable camera holder will eliminate even this small variance. It shows what seems to be a SN remnant?

This second image of M16 region is 3nm NII to red and HA to green. Exposures 10x4 min for each. 8MB

Even at only four minutes exposures really faint NII and HA are being recorded.


The SMC is still low in the sky so I limited the RGB to 15x2 minute exposures. The NII was 7X8 minute. Here is a blend of NII and RGB. 4 MB

I was not going to put these up as they are only tests of the system. They are a good indicator though of what the system is capable of.

Here is an animated gif of a crop from the SMC image enlarged x3 compared to the same area from a mosaic made with the 300mm lens. 2MB
