Thoughts on widefield 'scope...

Hi everyone,

Her indoors has generously allowed me to buy a second widefield 'scope, (budget around $2.5K woohoo!) to compliment my existing WO FLT110.

I mainly shoot nebulas in NB, often but not always from the burbs with bimonthly dark sky trips.
I'd like to go wider than the 1.67x1.3* which my current FLT110/0.8 reducer combo will allow on my QSIwsg8 sampling at 1.81" p/pixel.

For example a William Optics Star71 will allow 2.96x2.30* - but I understand the sampling will be around 3.2" per pixel which is maybe not ideal?

A 2nd hand Tak fsq85 is almost in reach of my budget and samples at 2.47* p/pixel with a FOV of 2.29x1.78*

Of course I could also consider parting with the FLT110 which would add another 2K or so to the budget, but then I would only have the widefield scope, yada yada etc. hmmm.

Happy co consider other suggestions and would welcome input on the whole resolution v. sampling p/pixel thing.

cheers
Andy
