Skywatcher 750mm F5 and prime focus photography?
Hi,
I've been thinking about getting a T-adapter for the DSLR that I'm about to buy, so that I could also try some prime focus photography. Unfortunately, I've heard that it's not possible with all telescopes, especially Newtonian reflectors, as it may be impossible to reach the focus point. So, what I'm curious about, is whether anyone has Skywatcher 750mm f/5 telescope and has tried prime focus stuff with it. The telescope is supposedly sold by many other companies as well with just a different name, and the original manufacturer is Synta. |

I have a 750mm f/5 refractor, for prime photography a extension to the
focuser was needed, A friend made one for on his lathe me , I have been told that Vixen Extension will fit the Synta scopes Phil "Mika Yrjola" wrote in message ...

So, what I'm curious about, is whether anyone has Skywatcher 750mm f/5
telescope and has tried prime focus stuff with it. Your scope is a Newtonian??? In most cases I think one cannot reach focus and the 1.25 inch focuser may cause Vigenetting. You maybe able to install a 2 inch Low Profile focuser and kill 2 birds with one stone... jon |

You can find out for yourself easily: point the scope at something reasonably bright (I usually use the Moon) and hold a white card off the end of the focuser to see where prime focus is. Then you can decide how to proceed. Laura Halliday VE7LDH "Que les nuages soient notre Grid: CN89mg pied a terre..." ICBM: 49 16.05 N 122 56.92 W - Hospital/Shafte |
