Hello everyone!
I want to build a Newton telescope with a dealuminated primary mirror to photograph the sun in white light, I live in Argentina and due to the scarcity of materials and specialized skilled labor to build a mirror, it seemed like a good idea to buy a GSO 10" f4 Newton telescope (truss tube) and modify it.
I would dealuminate the mirror and build a new rear cell to allow light to pass through.
What do you think of this? It could work?
Thank you very much in advance for your opinions!

Re: Dealuminated newton for WL
The only thing i would consider is collimation of a f/4 newton. Its quite demanding (precision) compared to longer newtons, and doesnt last as long, considering having no reference star during daytime use.
