[Max Vondel (Peter)]

I have for sale an upgrade for a 6" Newtonian.
Consists of:

- CNC Machined Spider 180mm OD
- Mirror mask 147mm ID & 168mm OD
- Metal back plate to prevent stray light near your primary mirror
- Screws and fitting to suit all of the above.

Designed for Skywatcher but maybe suitable for other brands.
Please check sizing for your telescope. Mirror not included.

Improves diffraction vanes and makes individual stars sharper.
A great upgrade for most 6" Newtonians
Price $xxx- including postage

Pls respond via PM Thx
