One is created from the raw images taken back at the end of december. I wanted to take more images, but by now the target (M45, Pleiades) are no longer in a good position in the night sky.

So I have to accept what I have.

The second one (Rosette Nebula, NGC2244) was taken a bit more than a week ago, with only one hour of exposure time. But this one also features the effect of the brand new SV220 3nm filter.

The optical train:

SV555 lens, SV238 OAG + SV226P filter drawer, SV605CC camera, ZWO ASI120 mini guide camera

In the case of M45 SVBony UV/IR filter. In the case of NGC2244 SV220 3nm dualband filter.
