a question re CLS Filters

[mgirdwood]

Hi All

can anyone confirm how the CLS Filter ( http://www.teleskop-express.de/shop/product_info.php/info/p4686_TS-2--CLS-broad-band-nebula-filter---visual-and-photography.html ) fits into the imaging train - i have ED80 with an SW reducer and canon m48 bayonet fix.

i would have assumed that it would screw on to the back of the reducer and then the bayonet fix would screw onto the filter, but there isn't both a male and female fitment to allow for that. the only option i can see is to lie it onto the reducer loose before screwing the reducer onto the ed80 -

a bit confused so any help is appreciated.

Reducers normally have female thread on the end that fits into the focuser, screw your filter into that and the job's a good'un.

thanks starflyer for the idea, but i just had another check and there is no way the the filter is wide enough to screw into the front end of the reducer. so its back in there just sitting loose at the moment.

I use one of these in front of the reducer, it has a thread for the 2" filters in the front. Otherwise if you put a filter in between the canon adapter & SW reducer you loose the correct spacing between sensor - reducer/flattener.
