Lee's and Clive's (Alchemy) articles are a good resource.
Best to read up and understand the consequences and benefits
before the cut.
I'd advise against mounting the mirror on longer springs btw,
although for a smaller 8" mirror, mirror flex might be minimal.
I did the cut on my 12" OTA, never looked back.
I can still do visual with a low profile Crayford focuser and an
extension tube/ tubes.
