planets + dso


Recommended Posts

For planets you need aperture (like 8") and for DSO you need short focal ratio and usually short focal length. SCT 8" is very good for planets, and in some excent for DSO imaging (even with 6.4 reducer/corrector it will have quite long focal length). 8" Newtonian may be quite hard to use even on HEQ5.

You may choose HEQ5 + C8/TAL200K + OAG setup and you are ready to go on globular clusters, small nebulas and galaxies.
