Hi and
,
Where to begin...? Okay, am not sure what that link is (doesnt work for me), but if it does have a long focal length, I would probably avoid it for a first scope.
If you search the forums, I think you will find that this question is asked a lot, and there is a wealth of information in the archives in regards to choosing your first scope.
In the mean time, you need to decide what you want from your scope. Generally, the golden rule is aperature, aperature, aperature. Forget focal length at this stage.
When starting out a dobsonian scope (newtonian reflector) offers the greatest aperature at the best price IMHO. These cost anywhere from $100 for a tiny skywatcher heritage (not all that practical) to many thousands. I started out myself with a skywatcher 10" dob and couldnt have been happier with its ability to view the moon, planets and deep sky. the bonus of buying a cheaper dobsonian is that you can later uprgade the parts (focuser, primary mirror cell, cooling etc) to make very capable astrographs etc.
I think the best suggestion that you will see coming up again and again is if in doubt, find one of your local clubs and have a look through some of their gear. Most are more than happy to see a new amateur astro fan, just dont get caught up in the fever of bigger and better gear, as I have not doubt that if you do go to a club night, you will see some pretty fancy gear.
Have a look at bintel.com.au (I am not affiliated with them) as they have a good selection and are good to deal with
Good luck
Sam
