My astrophotography 2021

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!

No luck for clear evening skies. Wish for chances of viewing the inner planets dominating the western skies at dusk.

But here comes an uncommon object for the early morning. The unusually bright nova in Cassiopeia, the Nova Cas 2021. It's light curve is special and in the last few days it brightened to mag 5!

Thankfully it was quite clear in the early morning. Went down to the Serangoon harbor. After shooting the lined-up three gas/ice giants (Jupiter, Saturn and Neptune), I mounted the small APO on the tracker. Today the ASIAir box worked so well with the tracker, the main camera and the autoguider camera.

I did not have high expectations for the exposures -- the target is in far northern hemisphere -- quite low altitudes from Singapore, and the misty/cloudy extended horizons add much to the problem. Plus, it was fast approaching daybreak. So I only collected less than 30min worth of subs.

The giant planets.

Again, Jupiter is crossing Aquarius, while Saturn still in Cap, and Neptune in Psc.

If all goes well, I will be able to track Saturn completing another full circle in the celestial. But no human being has ever been able to track a full circle of Neptune's motion (164.8yr) in his/her lifetime.

What a joy watching the lovely Mercury and Venus in the dusk twilight, accompanied by the crescent moon! Finally the weather turns well when it is the best time in May to enjoy the show of the two inner planets.

Don't ever forget that Mars is not far and marching in the constellation of Gemini.

The crescent moon is adorned by the earthshine.

I was trying to capture a picture of human-activity with the crescent moon as the backdrop. But difficult to find a suitable place in my neighborhood.

When I was back home, it was showing a vista of moonset.

The buildings are in the Johor Barhu CBD, at a distance of approx. 16KM.
