What can you say besides WOW!! A 300mm Ha refractor
Actually I would need 162.000,00 to cover DPH as well, I will pay the shipping myself

Don't forget the new mount that's gonna be needed to carry that monster!

You do not think my Vixen Porta mount would be enough?
I think mounting it on a DDM is a bit of overkill in the mount department since their smallest mount carries 100kg

I'll have to check my other jeans pockets to see if there is enough in them. That is a nice looking beast!

Nice but if you go big in solar observing you need adaptive optics, and therefore a reflector. At the RTMC there was a presenter from Big Bear who was doing the adaptive optics for the scope they have there. It was a great presentation, the effect of AO is amazing. See http://www.bbso.njit.edu/ .

I need to ask my club if they will buy it for us kiddies to play with

Actually, they do have over $150,000.00 worth of scopes at the observatory, so maybe they won't laugh at me so much

Well that settles that! Time to get the piggy bank and a hammer!

the check is posted

My stimulus check is late so I will have to wait

the truss tube desighn, small to larger od .. also, think of the better results a 135k eu ($209K aus ) newt would do

So your tower observatory to reduce ground turbulence is all set and ready for the installation?

Hydrogen Alpha viewing and imaging is at one wavelength so a Newtonian would have no advantage that I can think of. Actually if the CO is over 20% it would reduce contrast and resolution.
Perhaps I am wrong though?

Buying property on top of a mountain may be a idea

I've heard there's a guy in Nigeria that would be happy to loan you the money!!

He would be a real prince if that kind

A reflector would only offer an advantage if you included a deformable mirror apparatus and an adaptive optics system.
