Skywatcher vs GSO 8" f/4 CF newt
Hi there, ive been browsing my next big purchase and decided on a 8" f/4 cf newtonian. Andrews sells a GSO one for $600 whereas bintel has a skywatcher brand one for $1450. Why is the skywatcher one more than twice the price? Is there any noticeable difference? Ill (hopefully) be using it with the baader mpcc and 500d on a heq5 mount if that matters.

Good point , but I have heard that the GSO ones need a few adaptors/spacers to reach focus using a DSLR , not $850 worth tho ..
Focusers should be comparible but for imaging a Moonlight would be the go but people do good stuff with the standard GSO and SW focusers after a little tinkering .
Every GSO Newtonion I have ever looked thru has has very good to excellent optics and build .
Your HEQ5 should carry the CF tube easily .

This is not a straight forward comparison. Andrews are grey importers,
and as such can often get deals unavailable to normal retailers.
GSO and SW products are usually much of a muchness pricewise,
so I'm guessing that Andrews either got a great deal on a batch of GSO scopes, or are clearing out some excess stock. Andrews price for the 8"
SW f/4 CF imaging Newt is $1299, somewhat better than $1450, and also there is the SW five year warranty to consider. The GSO you mention is marketed as an imaging scope, so will probably not require any adaptors [other than the always needed T-ring] for use with a DSLR [the retailer will be able to tell you].

OOP's My iStar is better than my sold 127mm triplet ?
My C9.25 is better than my sold Takahashi Mewlon 210 ?
I HATE !!! scope snobbery ,,, have been banned more than once from our sweet IIS .
I have and love and use my iStar 127mm Achromat instead of a 127mm triplet .. Why ?
I have and love ( really do ) my C9.25 instead of a beautiful Takahashi M210 ?
The C9.25 beat the Mewlon ,,,,
,
Sold the Tak ,,, Yes I know scope snobbery and hate it .
Don't ask me about my ( SOLD ) Takahashi Sky90 When she is side by side with my Saxon 90mm f10 achro ??? .
i HEAR YOU ,,, SOME PEOPLE BEILEVE THAT BECAUSE YOUR SCOPE IS WORTH 3X- 10x THE OTHERS ,,,, ? ,,, ITS BETTER ? ,,, HELL YES MECHANICALLY YES ,,, OPTICALLY ??? THE FIGHT BEGIN'S .

Get the Baader, the GSO is a bit of a headache to use. Optically the GSO is similar to the Baader and it better to use visually due to a longer back focus but it is a headache to use for imaging.

I am having the same dilemma, from what I have read the GSO corrector is a sharp at the edges but bit soft at centre, so my choice is between the Skywatcher and BAADER, the skywatcher being $60 cheaper.... but I will probably go with the Baader.

That's a good price but I'd want it to come with lessons on how to collimate

The finder guiders are supposed to be good for guiding up to 1500mm focal length, mine works ok with my RC 6" (1350mm fl). Finder guiders are a lot easier to work with (set up, mount and line up) than a proper refractor as a guide scope.
