taken with a 10" dob.
screwdriver1 could i expect to see images like the on above using the scope u recommended?
200 x 1000P with HEQ5PRO Go-To mount (white) and V3.0 Go-To hand controller
$1399.00 AUD
(Why pay A$2795 elsewhere?) (with the right conditions of course )
or would you really need the extra light a 10" affords?
and the hand controller ,the go-to,do you enter where u are and then just enter the co-ords of were you want to look and it will 'drive' the scope there? sorry about the noob questions lol. cheers tony

Hi Tony,
Well, you probably could, however Mike is a gun at Planetary imaging so I wouldnt use him as a yardstick. The main reason I suggested the 8 inch Heq5 combo is the fact that 8 inch scopes are great starters and especially on GOTO mounts would do most things you would need them to do/see as well as Astrophotography later on either with that tube or a bigger one. See some pics from AlexN who takes shots using a webcam and an 8 inch Dobsonian Reflector.
As for the GOTO moung the HEQ5, yes, you align it, tell it 2 or more stars to look at and then you dial up the item or object you want and off it goes auto slewing to the target and then maintains tracking on it for as long as you want. Just like Argo Navis only built into the mount.
10 inch scope would give you more light and details, but its a trade off on size/cost and light gathering. Most people here I have seen joining start with either an 8 or 10 inch DOB or EQ mounted OTA.
I have a 5 inch Skywatcher and am screaming out for some more aperture to be able to see stuff. As they say, APERTURE RULES, so the bigger the better. My suggestion was a compromise to be able to meet your budget but it still is a great combination of gear to start with, especially the computer control afforded by the GOTO mount. Keep in mind Argo Navis is great but generally is PUSH TO ( like a GPS navigator in the car - where it TELLS you to go somewhere) and GOTO mounts are like Autopilots who take you there like a chauffer driving you there.
I hope this helps.
Chris
