Newtonian rear cell cover ?
Hi all,
I have a question regarding covering the rear cell in my newtonian. I have an 8” f/4 newt and the rear mirror cell is open to air ( and light ). It has a fan to cool the primary but the rest of the cell is open. I live in quite a light polluted area so I figured there may be some benefit, even if small to making a cover for the rear of the tube. Is there any reason not to ?
Thank you in advance for any advice
Ryan
