What Can You Image with a Celestron NexStar 4SE?



Here's my Celestron NexStar 4SE telescope
it's the "Tiny Scope That Could" !
I have it on a Celestron AVX mount
with a Canon T3i unmodded camera
and a ZWO guide camera

Most people assume you have to have a BIG telescope to image some deep space objects
like galaxies and nebula. And, yes, I have bigger scopes to astro-image with.
But I just wanted to see what this little scope could do.
The truth is that if you have a good mount that tracks well
this telescope (OTA) can give more than acceptable results.  Here's the proof...
