TRUE

Hi Guys
I had the pleasure of reviewing and using the first Skywatcher 18 Inch Dob to Australian shores, see review and pictures on the international Skywatcher website.

Nice one. But, if your open to constructive criticism. Ask someone to edit your publication first. Roomers? How did that get past your spell check?

Hmmm
Ribbed mirrors and silicon.....

Any serious evaluation on the optical quality ?

Update: I contacted Bruce Mills to get some measurements and details on his ultralight scope. He generously offered to sell it to me sans mirror but including the Protostar secondary and the Feathertouch focuser. As luck would have it a perfect fit 20"f4 Zambuto refigured 2" Pegasus mirror came up for auction on Astromart at the same time. When I got the mirror I didn't like the quality of the coating so I had Wayne Sainty at Saintech recoat it properly. All up total cost including shipping and coating costs was 8k.

The only changes I've made to it have been some Lightbridge style doughnut counterweights on the bottom to offset the weight of my Paracorr and Ethos eyepieces. Also I will be stiffening the spider vanes at some stage.

Because of the cloud lately I haven't had it out since it was recoated but I'm hoping for an opportunity in a weeks time.

Thank you Bruce Mills UK for building a beautifully svelte scope and Wayne Sainty at Saintech for the excellent coating job.

I guess it's like writing "your" instead of "you're"

Nice scope Barry . The mirror is certainly well ventilated

Nice catch

"your" meaning possessive of you

"you're" bring the contraction of "you are"

Good job some of us was educated proper like

Isn't it his spell checker? How does one engrish? #yoloswagatron420blazehandleitbbq

Thanks Mark, yes I don't expect to have too many cooling issues. I've just got to get around to making some sort of cover for the mirror.
