Medium-wide fields 2020

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!

2020-Sept-17

Early morning saw thinning clouds and patches of clear skies, after nearly a week, finally.

The primary target was photometry of Mira which is fast approaching the peak brightness. Today's measurement points to m3.286. Will it hit <m3?

At the same time, the Mars is nearby and also approaching the great opposition. Nice moment to frame both beautiful objects.

Another coincident scence is in Cancer the crab. Venus just passed the closest conjunction with M44 the Beehive.

Image

It was also the occasion to test my new toy of Sigma 50mmF1.4 Art lens.

Image

Finally, the Venus was rising up. Let's test the raw images out of my mobilephone.

The clouds were very annoying, however. I then chose to shoot the zenith area, with the mobile phone resting still. Back home when I was stacking the photos, I learned one thing: the images could hardly be accurately stacked if not tracked-- apparently the phone camera lens suffers from distorations -- leading to nonlinear shifts of star images.

Given the one cloudy night after another, I cannot miss the brief windows of clear skies at dusk. And probably the only object of interest is no other than the moon (and some planet).

A large of of the image is blown out by the shinning moon. Did a bit postprocessing to bring out some details and superimposed another picture of the moon itself.

Jupiter in the upper left corner. The tea-pot asterism of Sagitarrius is to the lower left. Many interesting galactic gems are present.

Capricornous

Only two deep sky objects (both are globular clusters) are visible.
