I've just pulled my CPC 1100 out of storage after about six years. To my horror I found what I thought was water but later discovered oil on my secondary mirror. After some internet research, I found out that this oil is from grease that resides behind the secondary mirror. I've managed to remove the corrector plate and then the secondary mirror cell for cleaning. So far I've managed to remove the oil and about 90% of the blemishes on the mirror, using isopropyl alcohol water and soap mix.
Now to complete the job I wish to remove the secondary mirror from it's cell. To do this I presume I just remove the collimation screws. My question is what will I find when I do and how hard will it be to put back together again and what grease should I use as a replacement? While the mirror is out of it's plastic housing I will give acetone ago at removing the last of the blemishes from the mirror.
