Refractor Aperture Mask

[Coco]

Found a great seller on eBay, made an aperture mask for my Bresser 127 L, while  by no means does not show terrible amounts of CA Jupiter does get spoiled a wee bit, so for less than a pint of draught lager I thought worth a punt, I have to say it's very well made, shame matt black wasn't available so I'll flock it.

Whilst undoubtedly a good idea and it looks a snug fit, why didn't they just cut it out of black?

I'm currently CAD designing an 80mm mask for my Evostar 120 that is the hood cap with a [threaded] mask aperture over which you can screw a 'cell' for Baader solar film, over which you can screw a cap fort the mask and film holder. All it needs is my CAD accuracy to catch up but having 3D printed a really nice fitting cap already it shouldn't be too much work to print for a couple of quid.

They didn't have black, I've flocked one side and painted the other.

I'd love one of these. Can you share some details by PM by any chance?. Thanks Rob
