Coma corrector for SW Explorer 150PDS

[VigdisVZ]

Hello SGL.

Since my AP is progressing nice I thought it was time to start working on quality. As you can see from my M45, the coma at the edges is pretty bad.

My question is, for my F/5 150PDS, what coma corrector do I get?

There is the Baader MPCC http://www.firstligh...aader-mpcc.html

And the Sky Watcher one http://www.altairast...productid=16316

Both should work on paper.

Then there is the issue of how to install it. The MPCC states that it should be a certain distance from the sensor array, how to I measure that?

Thanks for reading!

Edit: Actually I seem to have answered my own question, as the Baader seem to be out of stock everywhere. Looking at the SW... going to look around fo the best store to buy from....

I just got the Skywatcher one, FLO said they're not expecting the MPCC until Feb :/

Have you had a chance to try it out with a DSLR? Is it fiddly to install?

I don't use a DSLR but the whole setup is pretty straight forward. In fact the corrector is T-threaded so you can screw straight on to a T adaptor to DSLR

I think you'll find it's M48. Don't mangle it up with T.

Adapters are available.
