Hi, Does the mirror not sit on the cell and the springs under the cell to hold a tension on the three collimation bolts, have never heard of the springs being placed under the mirror, unless I am reading this wrong. Rick.

Hello Vince, welcome to the lounge. Rick

bobro, Not that I am an expert on secondaries, but years ago when I was making my 10" mirror I had a similar situation where as I wanting a higher then average secondary to go with my mirror, after a long chat with a gent whom made many high quality mirrors years ago, ( he worked at an optical lab for space agency ) he told me unless you are using the scope for photos, which I was not, the human eye can not tell the difference between a 1/8th and a 1/20th wave secondary. Now others may chime in and say hey wait a minute, but I ask you... are you wanting to take images...then maybe, go for it, but unless that secondary is totally horrible, I would stay the course, enjoy what you have with the better primary optics and get everything you can get outta that telescope. just my two cents, take care. Rick p.s. let me know what you decide, I am interested either way
