The Mirror set has been sold. Thanks Steve
I have a 20" f5 primary mirror, and a 3.5" secondary elliptical flat for sale. Together they made up a 20"f5 dob that I built.
The primary was made by Mark Suchting in NSW, and the secondary is from Protostar in the US.
The views using these mirrors in my scope were absolutely sensational, a real testament to the quality of Mark's mirrors and Protostar's secondaries. Jupiter and Saturn and the moon were magnificent.
The coating, about 5 years old, has a few minor marks on it, but nothing that would affect performance. The mirror really is excellent condition, but I have discounted the price to contribute to a re-coat if the purchaser thought it was required.
I increased the secondary size of my dob from 3.1" to 3.5" to allow me more felxibilty to switch between using a Mallincam Camera and visual use. So this $400 secondary is just a couple of years old, and in mint condition.
A similar new mirror set from the US would cost around $5750AUD after GST and customs. I am offering this set for $4200AUD, with freight costs by me to anywhere in Australia. I can send some photos to interested ones.
Thanks for looking
