QHY is bringing out a 16.2mp camera with OAG and filter wheel like a QSI for US$4K later this year. Its 28 x 18 or something similar. google QHY16200A.
6 micron pixels would suit widefield short focal length very well and your refractor should be able to handle that size chip without trouble.
An 8 inch F4 Carbon tube Newt would be 800mm focal length.
An STL11 comes up every now and then but they typically go for US$3800 to US$4300 depending on condition, filters, accessories.
Astro cameras are very expensive.

Thanks Greg, yes astro cameras and TAKs are very expensive and I doubt the missus would understand my wanting another camera having only gotten the QSI last year!

Thanks Paul, yes the options for buying wide field triplet APO's new seem to be as follows...(the Televue is a doublet).
-Orion ED80 f6.0 480mm with 0.8 reducer/flattener at under $1800 from Bintel
-Stellarvue 80 f6.0 480mm with 0.8 reducer and a feathertouch focuser at $2800 landed probably closer to $3k with GST.
-WOstar71 f4.9 needs no flattener and is 348mm so has the widest FOV of all 3 scopes for around $1500 landed+ GST
Have to say I'm leaning towards the WO at this stage but would welcome opinions about the other candidates.
Cheers
Andy
