So I picked up a classic... a 1970's - 80's edmund optics f6 150mm newtonian...
... like this one but mine has a different mount. It was cheap. Very good condition. The focuser is pants. The mechanics of the secondary holder is (IMHO) brilliant and apparently the primary is 1/10th wave.
But its f6 and I trhink I'd rather swap it out for a faster synta f5 mirror. . The thing is its a one shot job bc to make the f5 mirror work I will have to saw off a good few cm from the barrel of the scope.
So the question is: Is a high quality f6 mirror better than a faster synta f5 mirror for wide deep space astrophotograhy?
All comments gratefully received. 😉
Hi there! I’m looking forward towards purchasing a new wide FOV eyepiece from FLO (first light Optics ) and I do to know which one to pick!
i will be using it on my f/6 8” Skywatcher dob and hoping to get good views of the Orion’s nebula , (large nebulae in general) andromeda and others.
I ve heard the panaview 32mm is a good choice but I d like to know about the other options as well. I would like the budget to be around 100€
Clear skies, Kronos.
The Wizard Nebula
An emission nebula 7,200 light years away and my first proper project of the new imaging year.
Really happy with it as I’ve had a steep learning curve with new kit so really pleased to see this image come together. It’s also the first time I’ve imaged it.
