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!

NGC 3372 from Singapore in SHO mapped colour

Post by ivan » Tue Jun 21, 2016 4:00 pm

Recently, Singapore has been 'crowned' as the most light polluted city in the world, signifying the gradual loss of the night sky and our connection with the cosmos. Thankfully, there are still fruitful avenues to view and photograph the night sky despite the seemingly relentless march of light pollution, and one of that is through the use of narrowband filters which work on emission nebulae.

Here, I present a (relatively) recent work done from the balcony of my home in Toa Payoh, photographed on various clear sky nights last month. It features NGC 3372, the Grand Carina Nebula, which is the brightest nebula in the night sky. This tri-colour image was produced from images shot through Sulfur II, Hydrogen II, and Oxygen III filters and mapped into the usual RGB colours using a quasi-Hubble palette.

The total exposure time is 3.5 hours, shot through an 85mm refractor.

Thanks for Looking!
