Great shot considering the severe light pollution here in Singapore! By the way I can definitely vouch for NoiseXterminator, it simply works like magic!

Digging into the data collected over the past few months, I stumbled upon this gem of an emission nebula in Carina. And no, it is not the Carina Nebula. Well, from the picture below you would have seen that it is instead the Statue of Liberty Nebula (NGC3576), together with 2 other prominent HII reg...

Based on the results from image analysis, it would seem that the limiting naked eye magnitude at my observation site in Sengkang should theoretically be 4.8. However, I regret to say that I am unable to see stars so dim even after having reasonably dark adapted. Under the best conditions, I was able...

I am using a ZWO ASI2600MM Pro camera for most of my astrophotography works, so the test will be done with it. The formula for the light pollution rate is given as such: light pollution rate = (median ADU of 1 light frame - median of master bias frame) * electrons per ADU / the exposure length of th...

Having fallen into the rabbit hole of astrophotography for 2 years, I have plenty of imaging nights under Singapore's obnoxiously light-polluted skies. As such, I have been mostly limited to doing narrowband imaging with monochrome astronomy cameras to minimise the adverse impact of these manmade ph...

WOW that looks very good!! How did you manage to find 20 hours of good weather?! With my set-up on the balcony, I pretty much just shoot every single night now as long as there is clear weather. No more lugging the heavy scope + tripod + mount around in the night, battling the mosquitoes and the he...
