Ccd eos adapter

[geordie85]

Hi

I've been looking at adapters to use my atik 383l with canon lenses and I really don't think the geoptik or ts optics ones will allow me to achieve focus with my starlight xpress filter wheel. Whilst searching the Internet I have come across this https://www.astromarket.org/accessories-5/adapters-5/t2--m48-adapter-for-lenses-5/ccd-adapter-eos-lens-to-t2-2-filterthread830217-5?language=en which would atleast let my use my 36mm unmounted filters.

Does anyone have any experience with these? Or maybe found an adapter that works with my CCD and filter wheel? 

If so I'd like to know your thoughts or advice.

No one have any experience with the above product or worked out how to attach ccd, lens and filter wheel? 

[Skipper Billy]

Its probably not much help but I looked at the Geoptik etc for mounting Canon lenses to my Atik 460EX and came to the conclusion that it couldnt be done with my Atik EFW2 filter wheel so I abandoned the idea.

Looks like I have 2 options. Abandon the idea or take the plunge and try the above product.

Hiya,

How about this one? http://www.teleskop-express.de/shop/product_info.php/info/p6991_TS-Optics-CCD-Adapter-for-Canon-EOS-lenses-to-T2---only-10-mm-length.html

It's only 10mm long, will that get you to the right back focus?

It's what I use with the Atik One and Canon lenses.

I've got one of those but I've only used it with the Atik 4000 OSC

No it won't, according to what I've been told. 17mm back focus from the sensor plus 10mm from that ring plus around 25mm filterwheel puts me around 10mm out.

The back focus of your ATIK 383L  is 17,5 mm; Your SX filterwheel ads another 29mm .. so yor total backfocus for camera and wheel wlll be 46,5 mm, so that will not work with your Canon lenses for they are 44mm backfocus. I did not even mention the focal length you need for the adapter Canon lens to T2

Your only option will be  a filterdrawer system. The one you linked is 22 mm total focal length, including Canon adapter and T2. plus the 17,5 mm of the ATIK makes 39,5 mm. That means you will have to get a spacer 4,5 mm ± 1mm, or change the T-2 adapter. http://www.teleskop-express.de/shop/product_info.php/info/p5731_TS-Optics-Optics-T2-Zwischenring-Verlaengerungshuelse---Baulaenge-3mm.html
several are available @ Baader. Buy a set of adjustment rings (http://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/astro-t2-system/baader-t-2-adjustmentspacer-rings.html)  as well, for you will need to get the exact distance by trial and error.
