opinions on new scope
Hey guys , Ive come to the conclusion that my 4" reflector is in need of a upgrade, so for the next few months il be doing some overtime at work to buy a new 8" scope.
Ive found one that I am interested in, was hoping I could get some feedback into what you guys think of it 
What I want to use it for is DSO mainly , and maybe in the future , I might try astrophotography..
I would be needing it to be fairly portable as I need to drive about 1hr out every time I want to go observing
I looked into a 10" but i think its too big..
From my local supplier:

Looks OK but it appears to only have an R&P focuser not a crayford one.
If astrophotography is further down the line then maybe have a look at the GS scopes (dobs) from Bintel/Andrews and get a GEM for it later when the AP bug really starts to bite. Make sure you get the model with the 10:1 Crayford focuser if you go down this line.
Just my two bobs worth

Hi Ash
That mount won't be suitable for most astrophotography either, it's probably a little underweight for that size scope.
You could buy an 8" or 10" dob to start with, and an EQ mount (HEQ5 or EQ6) later on, when the astrophotography bug bites.

Hi,
Not posted many times but looking for advice re upgrading. Well, my old telescope is a retractor that frankly remains unused often as it is annoying, so I am looking for advice on a scope around $300 to $400 so I can take trips out of Sydney and introduce my son to astronomy. Any advice much appreciated....thanks.

Hi, what's annoying about your refractor, and what are the specs?
Obvious choices for me are the 6" ($299) or 8" ($429) Bintel Dobsonians
Probably the 6" and spend the rest on 'stuff' like planisphere, red LED light, etc.

My refractor is frankly too cheap so it is hard work to get good results. Was looking to see nebulae etc....not so much high spec but useful all the same. Basically reasonable quality at their low end of the range. Thanks

For $300 you could get a 6" dob from andrews, maybe even a 8" wich should let you see a fair bit - and still should fit in your car of its not small.
Look up andrews in the links section. They are located in western sydney. Go to Guan sheng scopes (on their webistes) and the dobs should be there.

Portability
If you are thinking about fitting the scope in a car then tube length is likely to be the main concern. Now the 15cm, 20cm and 25cm GSO dobs are basically the same length - they just shorten the f ratio as the size goes up. The 30cm is the first one where the tube gets longer, and it is a good step up from the 25cm. Google Guan Sheng and you'll find all the details.
As for how to spend you money wisely: think about the max you can afford then double it. In the long run you'll spend less that way. Don't put money aside for all those extras you'll want (better eyepieces, obs chair, warmer clothes etc etc). If you take that to its (il)logical conclusion you wouldn't buy a scope, just accessories. Those extras can be bought a bit at a time in the future from some future funding pool . Start by getting a scope you will use for years.

Yes I would recommand Andrews in Greystane. Very friendly people there. Ask for Luke. I buy from them many times in the last year or so.
$399 for a 8" GSO Dob with 2"Crayford focuser and plus. Check this out:
http://www.andrewscom.com.au/site-co...-guansheng.htm
I owned a 8" Dob for 10 years only upgraded to a 12" recently. Never regret.
Cheers

Hi,
just ordered the Bintel 8" BT202. Thanks for the advice and by going to the 8" it seems as though I have edged into the low end of good optics etc, so I am sure there is plenty of great discoveries ahead. Great to join the club!
When living in Christchurch for nigh on three years 97 to 99, I had two great fortunes:
1. To see a brief green curtain of the southern lights over the city. I have a newspaper article on it stored away. I should find and scan.
2. Visit the Townsend Observatory a number of times, located in the gothic revival stone architecture of the Christchurch Arts Centre - originally the first university. Here is link to the web page to see the dome and the telescope - http://www.phys.canterbury.ac.nz/townsend.shtml
The Jewelbox cluster featured one night. In summer though, viewing is much restricted due to the late hour of real night / dark, at times, around 10.30pm.
cheers
