I always wanted a crisp shot like that with such widefield array of stars. Mananged to get some simple shots however I guess I am facing an issue when it comes to ISO. Whenever I set anything abt 400 ( even for dark skies at Changi CP1), I get a washed out photo!

I was so clueless. And guess what I did? I exposed for 1 minute 30 secs(as long as I don't see obvious visible star trails yet) and ISO 100 and F3.5(that's the lowest I can get in my DSLR I guess(Sony SLT A65). I guess my problem was exposure time. Should have kept it at 30 seconds and at higher ISO. Now I realise how dumb I was
And there was once I took a shot at ISO 1600 at a much shorter time but my shots contained so much of noise. I don't quite get this..do u guys as well face such issues?
Don't mind my ignorance! I am still learning.

No worries. If it makes you feel better, what you are experiencing is something that we all go through, even now.
It's good that you know the basics of photography and noise. Correct. ISO = noise (and sensitivity to light). Shutter = exposure to light and Aperture = volume of light (for want of a better explanation....)
You're not alone in terms of noise. We all get that. And I won't be surprised if your photos end up looking like this:

or even brighter and washed out.
You know what? Our photos start out that way too!
To change the exposure, contrast, shadows, highlights and colour, we usually tweak the photos in an editing software (whether it's photoshop, lightroom, gimp etc).
We also sometimes use a "stacking" software to combine multiple photos of the same exposure and the software helps to remove noise + hot pixels while retaining the constants (i.e. the stars and possibly structures). One free stacking software is DeepSkyStacker (

Small steps, that's my advice for now. There's a lot to learn in astrophotography and even I am only scratching the surface. Other members here have been doing it for a long time (and their stories will probably scare the crap out of me lol).
