| Comment : |
This is a really big nebula, too big to this telescope.
It covers the whole field and more.
My shorter 300 mm telescope had fit better.
The sad thing, this nebulas as others emit at the H-Alpha 656 nm wave length.
Something the a standard DSLR camera can't receive very good.
It must have the IR block filter removed, later some day I fix that.
There isn't a trace of the nebulosity on the photo.
Here is a plate solve of the nebula
