Coma correctors

[toml42]

Hi,

I'm hoping to get a dslr over the summer and have a go at some deep sky astrophotography. I'm thinking with my scope a coma corrector might be necessary.

Has anyone got any experience on using a coma corrector with a 200p, is it required kit if i want to get into deepsky? And would i notice much visual improvement if i left it on when not imaging?

Also, is there a significant difference between the specific brands, i know skywatcher do their own one, might this be more 'optimized' for the specific aberrations in a 200p?

Cheers,

Tom

[bump] I'm interested in this too.

Question was asked a couple of weeks ago, see this thread.

Not much info on the SW correctors but I think the Baader MPCC's are popular, there is 2 versions available one version for astrophotography and a visual version. Looks like the SW comes with the necessary adapters for visual as well according to FLO.

Tempted with the Skywatcher version. Especially as it includes the adapter ring for the older focusers so you can ditch that silly adapter arrangement.

Am I right in assuming the 'silly adapter arrangement' is not needed for the newer SW scopes with the crayford focusers?

[russ]

Still needed for the models that use the single speed crayford (all the dobs and non-DS Explorers). But strangely in the USA all Skywatcher dobs have moved across to the dual speed crayford. So for some reason we are getting a rough deal from Optical Vision.

Thanks for the info Russ. Been looking at upgrading the focuser to dual speed crayford anyway so I guess I will do that before purchasing the CC.

Thanks everyone, DS focuser for me then, I've been waiting for FLO to get them back in stock.
