Experiments with optics
I was trying to match the Celestron 0.63reducer with the FLT132 .. 
This combo suppose to reduce the FLT’s F7 to F4.4 and make it 583mm scope. And guess what: it DID!!! 
Although guiding was an issue yesterday, here is a single 900s Ha (just stretched) frame of wide NGC3293+NGC3324.
