Hi Valery, Hi MArk
thank you very much for your comments. So we have to pack the LUNT50 in between a collimating system to get decent results , haven't we ?

Yes, but if you need them to work at 100% potentialswisswalter wrote:Hi Valery, Hi MArk

1. real 0.7A
2. maximal sharpness (no spherical aberration, no astigmatism, no field curvature) with Shtrehl >97% for full disk
3. full disk with prominences in Ha in the eyepiece (with binoviewer too)
4. no need to buy any ERF or D-ERF
5. have a 0.5A with no wings, in 5 min (for large scale imaging)
6. Extremely compact
Then this must be specifically correctly designed and made 100% according to the design. Yes, this cost it's money, but well worth it.
Even in our far not rich country, some amateurs who saw it's work, bought it next day. You all already saw the images taken through
such a system.
