RM300 is way too low for a true astronomical telescope, blueye. At the minimum, if you want to do basic visual observation (forget about astrophotography at this entry level) be prepared to spend RM1,500++ for one with at least a motor drive for sidereal tracking (to compensate for the earth's rotation).

Get something less than that, I guarantee you, you will lose interest in astronomy out of sheer frustration in no time.

Unfortunately, it is difficult to get a reasonable second hand telescope (except from a friend) because most people will only sell off a used telescope if it is an under performer.

I don't wish to discourage you, but you are only wasting your money if you invest in equipment at too low an entry point. Upgrading a telescope usually means buying a new one with larger aperture and sturdier mount  - you will be replacing almost all your initial investment.

Yup, he is right.

By the way, DSO is not a type of telescope. It's the short form of deep sky objects.

There are other ways to start astronomy as a hobby cheaply. Get a good pair of binoculars, join a club etc.

How about getting some friends together and share the costs? You can hold star parties the whole year round!

BTW, don't forget to shoot this Friday morning's Partial Lunar Eclipse! Can use almost any camera for this event. rclxms.gif rclxms.gif

When is the exact time for the partial lunar eclipse? Don't you think that we need a filter to protect the lens of the camera as it's not full eclipse?

For Petaling Jaya, the moon should be entering the penumbra at ~12:46 am on 8th September, and the first contact with the umbra at 2:12 am.
Peak is somewhere about 2:56 am, then it's out of the umbra at 3:30am and the eclipse is over at 4:57 am. Shouldn't be much different for Kluang. (Disclaimer: the mentioned times maybe off by a few minutes, too lazy to confirm)

Maybe you can use a neutral density filter, but easier to just reduce the aperture or exposure time.

Let's try to do a sequence from start to finish, like what wKkaY did during the last eclipse in Australia.....

Try for 7x magnification with aperture of at least 50mm. The bigger the aperture, the more details you can see. Mr.LKM is using a pair of Giant 9x63mm binos.... drool.gif

With the binoculars mounted on a camera tripod, you can easily observe the moons of Jupiter!

You can probably get a pair of cheap 7x50mm binos for between RM200-300. Of course, high quality ones may cost a few thousand ringgit - even more than a telescope because binoculars are actually a matched pair of small telecopes.

You only need a simple adapter to mount the binoculars on a normal camera tripod.

I thought the time for the eclipse is 6.05-7.38AM 8 Sept. ? Is our time GMT+9 or GMT+8? I think the stupid Mahaxxxx changed our time zone. Such a non scientific decision.

Yup, mine is a 9*63 and it's quite heavy. I seldom use them lately as I prefer to use my telescope. laugh.gif

GMT+8, no daylight savings for Malaysia.

If you don't compare with really good binos, they're perfectly okay. biggrin.gif

Can buy from photoshops, supermarket, pasar malam ( shakehead.gif ), or specialist shops ( sweat.gif ).

First number usually refers to the magnification - ie 7x50 means 7x magnification, second set of numbers is the aperture: in this case, 50mm diameter.

2.5*24-60 is i don't know what. rclxub.gif

Try not to go for zoom binoculars unless you find the quality okay to your eyes. Most zoom binoculars are too light limited and poor in viewing angle.

My 9*63 is RM420. laugh.gif Interested to know my telescope price? laugh.gif

I would say that 7*50 is very good as it's light and quite okay in sight viewing. I get mine from the South East Asia Meade distributor aka Uncle Looi in Petaling Jaya. smile.gif

I am so glad that this thread is active again. rclxms.gif March05, I thought our time is adjusted due to Sabah and Sarawak?
