Hi, Sorry if i have got this in the wring section, couldn't really find the correct section as it refers to a few different types of scope.
So first off i want to move into a completely dedicated scope for use on only Planetary visual and planetary imaging.
I currently have a Skywatcher 16" Dobsonian that is on a goto mount.
From my location and i think i have it collimated pretty good, i can usually use a 100 eyepiece to view Jupiter / Saturn, and smaller eye piece tends to make the planets start to get a bit fuzzy, this work out to a magnification of around 180x
I was looking to move into something like either the Skywatcher 180/2700 mak, of a Celestron C14, two very large price gaps differences i know.
Now i have been playing around with the stronomy.tools calculator to find out the difference fields of view that the different scope produce with certain lens.
I am hoping some on here might be able to offer a bit of advise on what might be the best way to go.
Going from my 16" Dobsonian and working of 180X as the highest magnification available at my site, ( i could be wrong on all this though )
The Skywatcher 180 / 270 mak with a 15mm eye piece give around 180X and a much closer view of Jupiter
The Celestron C14 with a 20mm eye piece give you roughly 195X magnification and a slightly less closer view of Jupiter.
Now when i put in the planetary imaging camera ( ZWO asi224mc )
the Celestron C14 give the closer image, then the 180/270 mak flowed by the Dobsonian.
So i was hoping i might be able to get some advise on what would be the best option to go with there.
A lot say the Dobsonian is a great scope, bit from what i am seeing is that both the Skywatcher 180/270 mak and the Celestron C14 will give much closer views both through a eyepiece and also via the planetary camera.
After all that, then you come to barlows to get the f-number up to what i believe to be the sweet spot at around f 20.
For the Dobsonian that would be around an 5x barlow and i an thinking for the other two a 2X barlow.
Any advice would be greatly appreciated.
