Some Pictures from July Punggai Trip

CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!

Oh wow...these shots are great Kelvin!
Looks like you had a very productive first time there. [smilie=cute.gif]

Hi,
WOW!! Very beautiful... [smilie=wow.gif] [smilie=good-job.gif] A mod DSLR does make a HUGH different... [smilie=woa.gif]

Have a nice day.

A question from a newbie: How does it work? When you attach a camera to the telescope, are you imaging at the Baby Q's focal length of 450mm (ie 9x mag) or is the power increased by some other eyepieces/magnifier? Thanks for the advice!
Hi Cloud Cover, sorry for the late reply, yes essentially you use the telescope like a supertele lens, it's imaged at prime focus. ( ie: at its native focal length , f/5.3 ) :)

Wow! I never knew DSOs could be imaged at that sort of focal length. I always though you needed hundreds of mag power to get the kind of size you made (uncropped, right?)
Looking forward to a trip up north to try a 400mm lens :)

Yes depends on what objects you are aftering, in relative term, these pics are consider 'widefield' images in astrophotography. Similar to 'normal' photography, size of the imaging sensors (CMOS/CCD) relative to the focal length of the ota/lenses, will determine the magnifications.
Of course, this just half of the story, you will need a mount capable of tracking/keeping up with the moving skies. Our fellow Singastro member Meng Lee wrote a good primer on astrophotography, this will provide a good reference : http://www.singastro.org/viewtopic.php? ... phy+primer [smilie=cute.gif]
