My astrophotography 2022

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!

2022-Apr-25 Kept tracking the planets-moon co-motion in the morning sky.

I missed last morning's moon-planets alignment -- I was not sure if the so bright moon would make the images of the many-magnitudes-dimmer planets any impressive.
This morning the moon had moved to the side of Saturn. But still way too bright.

I would probably skip tomorrow morning's alignment again. But hope for clear skies in the subsequent mornings -- there will be great visuals of the much thinner crescent moon vs the planets.

Another impromptu super short trip to Desaru again. Arrived in the evening and left around 11PM.

However it was a little bit cloudy in Desaru. So I went up J173 in total darkness towards Sedili, and stopped at road side a few KMs from Tanjun Sedili beach -- there was a vast open field with a nice unblocked panorama view 360. The skies were noticeably darker compared with those of Desaru. (It is Bortle 4 and SQM21.67 according to lightpollutionmap.com, but much better than Desaru beach's SQM21.3). I was happy shooting but it did not last long before the clouds crept in. I gave up and got on the long return trip via Desaru.

My plan for Desaru astrophotography failed but I returned with a discovery of an excellent Bortle 4 site.

My stock Sony camera finally saw some hydrogen emission under the dark sky.

Play with lights under the big dipper.

Went up to Desaru coast with family and spent two nights there. The first night past 12AM saw my wonderful times enjoying astrophotography.

This was the third trip to this location of three in a row within the span of 1 week. And the moderate light pollution has become a little pain to my photos -- guess it would be worth some extra trip due north to escape the sky glow -- but that might not happen until late May?

This is a composite image but my favorite.
Image

The core region extends to Altair.

Image

Always like to add interesting foreground to the Milky Way image.

Image

And so be it like me doing stupid things.

Image

And I guess 20mmF1.8 has become the staple lens for shooting MK in this location.

Image

Image

It also does star trails nicely. (And this photo gives some sense of how much light pollution you would expect from a small town 30~40KM away -- see the leftmost portion of the horizon).

Image

The pre-dawn hours saw the sky turned quite cloudy -- making it difficult to capture nice views of the planets alignment -- especially the Venus-Jupiter conjunction. But that was some rare astro event I never want to give up.

Back to commercial remote telescope service. A high quality ASA H8 astrograph + a high-resolution camera 600M looks a great pair to capture large-size wide field astro images. Always intrigued by M22 which is located in the dense Milky Way star field, I wanted to see some initial result

The full frame (reduced to 4K resolution) looks fabulous on a 4K display.

The full moon of May 2022.

The first image was created as a result of some mysterious mistake in the RawTherapee program that saw the curve profile skewed. But I like the effect.
