I don't use a filter wheel but rather a filter drawer and want to acquire an opaque filter to use when taking BIAS and Dark frames obviating the need to take the imager off the scope.

 

I did a search but did not find anything. Can someone point me in a good direction or give me better search terms.

Thanks for all of your suggestions (EXCEPT for the can of black paint - sheeeeeesh! wink.gif ). I didn't have a good search description and youse folk pointed me in the right direction.

 

Ladyhawke - I got the filter drawer from Starizona ( a very good company, BTW) and their price for the dark filter is right where I wanted to spend. Thanks.

I use the Orion dark filter as a space holder in my EFW-2. Pretty happy with it and was at a good price.

Thanks Pete, but I will also have to purchase a separate filter holder from Starizona.
