It is quite intuitive to practicing imagers that Bortle class do vary over our small island. (Refer rifleman175's A Method of Determining the Bortle Class at my Observation Site), i do agree with rifleman's finding that "the light pollution at Senkang is around Bortle 7.0 at altitude of 55 deg...

Hi Bernard, Very nice images. I'd actually venture to guess that it's really Bortle 7 to 8 at you location rather than Bortle 9 from your images. I'd suggest that you start stacking more than 30 subs (1 hour at 30 s is 120 images, 3 hours is 360 images) and then process offline. Looking at your dat...

My second attempt at astrophotography from our Bortle 9 skies. Nothing fancy, just UV/IR filter with uncooled zwo585mc camera, sharpstar 61edph iii w reducer/flattener (FL 268mm, F3.9), iOptron cem26 (unguided). All without darks, flats etc, unprocessed other than live-stack using asiair mini. Omega...

It was clear until just after midnight, when patchy clouds started to drift in. At that point, I called it a night and packed up. It was also getting very balmy

btw, my photos from last night are in this thread

I was able to do some imaging tonight from 9.30pm - 12mn. Will upload the live stacks tomorrow.

Yeah, skies looks clear now and I’m hoping it continues to 1-2am Keeping fingers crossed

So much for the iOS weather app and our Meteorological Service. A few hours after I posted, the forecast for the night changed from partly cloudy to cloudy, and it actually started raining at 11.30pm

If the iOS weather app’s precipitation map suggests light or little cloud cover for the night, I check the skies every 1-2 hours to see if skies are mostly transparent. I find that the equatorial weather here is just too changeable for any forecast to be reliable predictor of clear skies. If the ski...

There was reasonably good skies around southern skies on 29-04-2024 from about 10pm to 1am. I manage to make a few quick snaps of a few objects in the vicinity. All taken with Askar FMA180 Pro with UV/IR filter on ZWO585MC (non-cooled), unguided. Mount: iOptron CEM26 with ZWO Asiair Mini. https://ph...

Ok. Reserved for you Mr Chia.
