Homemade Hyperbolic Astrograph - 3, OTA finished

[Chanlunlun]

it,s seem that Mr.Chan dont quite happy about our comment's on his new baby's outlook, but if he sell this baby, I will seriously consider to buy it.

Dear BingSze,

Oh my friend don't be silly. I don't mind at all. If it's ugly then it's ugly.

But I do feel grateful that Mr. Tang and Mr. A/45 had tried their best to paint it colorful, in order to make it looks prettier.

Best regards

Yes, appearance is just an appearance, we all know that the practical function is always the top priority in our MirrorGod's mind.... ugly feeling is just joking and that also means another kind of praise.

MG, good weathers are coming soon, we are all eager to see your good trials....

Dear god of mirrors,

How is the progress of this wonderful project? I suppose the mirror has already got its aluminium coating.

Dear Mr. tang,

Thank you for asking.

Just received the mirror from ZhiTong and the coating is not perfect. Nevertheless the effect is only psychological more than practical.

Before the shooting test can advance I need a focuser. Hopefully SY will not mind lending it out to me again.

Best regards

有点担心，方形镜筒不知会对星点的形状有何种程度影响

The side effects should be very mild I belief.

The true worry is - I have no ideas whether the conic constant of the hyperboloid primary miror matches with the MPCC corrector or not.
