[WITHDRAWN] 8" f6 Newt.

[alpal]

I bought a 10" f4 Newt a year ago that I now have operational.

I don't have the room to store my 8" f6 Newt so I am putting it up for sale.
It an Astronomy Alive 204mm Hand-Crafted Newtonian Reflector as per here:

You can see some of the photos that I took with it here:

I spent many $1000s on this before upgrading:
It has a JMI crayford focuser & custom Parallax tube rings - good for imaging -
I am also including some Antares rotating tube rings.

I am using the Telrad on my latest scope so that's not for sale.
The secondary is large at 2.2 inches which is set up for imaging.
Also - the secondary probably needs re-coating which I could arrange but I prefer to find out
first if someone wants this for imaging or viewing.
If for viewing a smaller secondary would be better for contrast ratio which I can organise at extra cost.
There are mirror mounting holes a bit further down the tube to adjust
the mirror for viewing -
it's set up for imaging right now but you can still get great views as is.
The primary mirror is still in good condition & is very high quality -
full annealed Finest Grade Fine Annealed Pyrex.

The system cost me well over $3,000 & I am offering it at less than half price for $1500.

Can you advise, the link you sent shows a telescope with an old Astro Optical primary mount , can we see what yours has? (I dunno why that photo is there as it must be wrong)

Hi Roger,
Some of the photos are old.
Do you mean the mirror mount? - the mount hasn't changed.
It's a simple mirror mount - it doesn't have a mirror cell
& doesn't need one for an 8".
It's not an Astro Optical primary mount but from Astromomy Alive:

PS - the mirror mount is NOT like this one:

What - no replies - I can't believe it.
This is a custom built hand crafted telescope of much
higher quality than you find in shops.

Look at how sharp this picture is - allow time to load the full frame:

That picture won the Cloudy Nights January 2014 CCD competition as you
can see from the write-up & link.
I saw an eyepiece tonight that cost over $2K so
the price I'm asking for a whole telescope with accessories is cheap.

I have changed my mind about selling this telescope.

I am organising a small quartz secondary 1/100 wave mirror to turn
it into a planet killer.
A smaller secondary mirror will give it a better contrast ratio
than the 2.25" mirror now installed making it fantastic for planets.
I will still have my new 10" f4 for imaging.
The primary mirror was made by a person who left Takahashi
to make their own mirrors so that & the high quality focuser with
the Carl Zeiss flocking paper already installed along the whole inside length
will give wonderful planet contrast.
It may also be good for doing high resolution pictures of bright
targets like the Trapezium.
