Bintel 8” f5 has 2” focuser
Set up is as follows
Nikon camera > Nikon T ring adapter > Baader Mk3 coma corrector > 2” Optolong L Extreme screws into end of coma corrector , then into focuser
From Nikon camera sensor to coma corrector should be around 55mm to achieve focus and eliminate coma
I have a Canon so I didn’t need any additional spacers to achieve focus and eliminate coma but when I use my ZWO2600MC cooled OSC , I needed an additional 2mm spacer to eliminate coma ( sensor to coma corrector ended up 57mm )
You will have to test your new set up and you may or may not need additional spacers or screwed rings ( available from Bintel )
Hope the above helps
Martin
