Ok so I got a new Orion FF, Orion Reducer and a Optolong L-Pro Filter (all 2in versions). I took a single 30 second image with a Nikon dslr with each just to compare. Note - seeing was very bad and my camera was set to jpg instead of raw (my bad). The only editing I did was to reduce the image size so it would fit here in CN. The bright star in the middle is Albireo in Cygnus.

Hope this helps anyone looking at the same pieces of equipment.

First 2 images are just a raw image with the ES 80mm APO on a CGX with eyeball focusing. You can see the corners are very bad and the L-Pro filter makes a huge difference.

The next images are with the Field Flattener and the FF with the filter. 

 

The corners are not perfect but far better and the filtered one is much better.

The last 2 images are of the Reducer and Reducer-filter

 

The corners are not perfect but not as bad as the first 2 images.

That filter does a nice job.  And I like that it has a bluer cast rather than the purple I see in most LP filters.

Could you post links to the FF, FR, and filter you used please. I have been trying to figure out what I might need for my ES 80 APO. I have a ASI 183 with a much smaller sensor than what I assume is a full frame in your DSLR. I may be able to get away without a FF. I have yet to do any AP with the scope yet so I am still evaluating options.

Thanks,

 

That's a bit pricey filter. I have an DGM NPB filter coming soon, i hope, backorder. I have been interested in the OPT Triad filter but can bring myself to drop $375.

 

Thanks again,

 

Chris
