Wide field OTA

[Simon Dunsmore]

Hi Folks, 

I was wondering if anyone could suggest a wide field OTA for around £150? I presently use a Skywatcher 130pds for imaging DSOs but I would like to consider a wide field scope also for astrophotography for use with a DSLR.  Budget very limited to £150 or very close. 

Thanks for your help

Hi

£150?

How about a 72mm flat field triplet?

Cheers

Thanks, how would the ST102 perform for astrophotography?

It would be ok but you have to know its limitations ..bright stars will have a blue halo as the light in an achromat doesn't reach a focal point , especially on the short focal length scopes . If CA bothers you it may be a deal breaker . 

But , yes you could certainly image with it .

You'd be over budget. For ap with a DSLR it's gonna need a field flattener:(
