Focal reducer for imaging with an ED100

[dc509]

Hi

I am thinking of using my Skywatcher ED100 F9 for deep sky imaging and am wondering if anyone has experience of using the Skywatcher .85 reducer or if there are any other products worth considering that will make it faster (until I can afford an MN190!!!)?

Thanks

I use the .85 reducer on the ED100 and it seems to work ok. What are you going to image with? If a DSLR then no problem, I use a mono CCD with filterwheel and have a problem with the spacing.

I'm going to be using a mono CCD with filter wheel also. Have you been using the Skywatcher reducer?

Yes I do, because I have an LP filter screwd to the ccd face I end up about 5mm to long.

I nottice you have a supaslim wheel as well! could be a bit of an issue. I have the same problem with my celestron when I put the reducer on it, with my pimped focuser - some EPs cannot achieve focus, luckily the camera can but it's not yet tested with the new wheel.

Maybe I should just accept that I need a faster scope for serious imaging, and stop buying long focal lengths and trying to fix it with reducers!!

Thanks for the help
