Have any SVX080T owners tried, or are using the Riccardi 0.75x FR? If not, what flattener/reducer are you using? Thanks in advance.

I use the original reducer that Stellarvue made for the SVX080. No longer available.

I would call SV customer service to see what they recommend. I only see the field flattener advertised on their website.

Thanks - I did review this flattener. Curious what owner’s experience was with this unit or if they are using another OEM flattener.

I had a SVX080T-3SV that came with the .74x reducer and could only get that combo to correct well for me a little past the "micro 4/3" frame. I still used it frequently with my APS-C ASI2600 (once I figured out the optimal backspacing) and felt that the results were tolerable after a slight crop, but I never could get it to give me good stars at the edges.

 

I once had a brief chat with Vic about it and he implied that the .74x was really made for their 102mm triplet, and their newer .8x offering (linked above) is now what they recommend for the 80mm triplets.

 

Incidentally, I wound up selling the SVX80T to move up to their SVX90T and planned to also sell the .74x, but after trying it on the 90mm I found it to be much improved (though still not perfect to the APS-C edges). I'd like to try their new .8x reducer to see how it compares to the .74x, but I haven't been able to find a used one and I'm not interested enough in buying new with the reasonable results that I'm now getting from the .74x.
