Hi Suzy see my input


1)Collimation. I hear the 10’s need this regularly, especially after every car trip?
Why is everyone afraid of collimation? after you have done it a few times it becomes second nature.

If you pack it in the vehicle well enough and the roads are not too rough, then there shouldn't be much of a problem.

2)Dew problems. More of a problem with a 10”?

The more glass there is the longer it takes to due up IMHO.

3)Cooling down period takes longer?

Set up a bit earlier, look at say Nebular/ galaxies until it as cooled enough to look at Planets

4)This is a fast scope at F5. How will this impact on my current premium eyepieces (Vixen lvw 22m, Petax xw10mm)?

Not to sure on that one?

5)The planets get very picky when it comes to less than desirable seeing conditions through larger apertures, as large apertures can magnify poor conditions that smaller apertures don’t reveal (as they don’t show as much detail). I regularly come across this point. Do I have to carefully pick my nights when I view planets?.

A small Fuzzy Planet is just as bad as a large Fuzzy Planet.
You take your nights as you find them.

6)Lastly, a valid point I’m about to raise. The only other two females on here that I know of that have got 10” dobs: JJJnettie sold hers, and Liz went for collapsible. This isn’t giving me much confidence.

There is a lady who is on iceinspace, but doesn't post who takes her 10" scope out as often as she can ( more than most males I know.
Liz and Jeanette can come in and give their reasons for doing what they did.

7)There doesn’t seem to be much of a difference between and 8” and a 10”, than
There is from a 6” to an 8”. I have detailed the differences below:

6” Resolving Power: 0.74 Faintest Stellar Magnitude: 13.6
8” Resolving Power: 0.56 Faintest Stallar Magnitude: 14.2
10” Resolving Power: 0.56 Faintest Stellar Magnitude: 14.7

From what I see, I see a whole magnitude difference between the 6 and an 8 (that’s 2 and a half times brighter, right?), but not even a mag. Difference between the 8 and the 10. I don’t doubt the 10 will give a better view on top of the 8, but from what it looks like there is a bigger jump from the 6 to the 8, than there is from the 8 to the 10. What do
you’ll think?

The 10" scope well out performs the 8" scope, an increase of nearly a magnitude is considerable.


I’m trying to keep in the forefront of my thinking, the classic line “the best scope is the one you use the most”. If the 10” ends up being quite a bit of maintenance (regarding the above points), I have to ask myself, would I really use it as much as I do now, in comparison with my 6”(despite stunning views).

That is only for you to decide.
there is a price to be paid for everything
cheers

I understand and appreciate that you'll are trying to give me the best advice, and believe me,I am taking everything you'll say into heavy consideration.
