More pictures looking to the heavens

Back in 2017, I wrote a post on beginner astrophotography as I was just getting into the hobby. It was mostly a collection of my very first Milky Way pictures that I took at the time. Since then I have been taking more pictures of the Milky Way, and some occasional pictures of the moon, planets and the aurora. So here's an update of my latest selected pictures in the same format as last time, with details in the caption.

This picture was taken at Cape Schanck, one of my favorite places to capture the stars. It's a single exposure with light painting, so the staircase is out of focus. 

One of may favorite pictures taken under perfect conditions. Moon was out on the opposite side of the Milky Way to illuminate the landscape perfectly. Location: Flinders

This is the first picture in which I was able to capture the reflection of the stars in water. Location: Lake Eildon. 

The daytime moon captured through my telescope. I attached the camera into the eyepiece of the telescope with a lens adapter. 

Two photos of Jupiter and Saturn also taken from my telescope. I recorded a short video and processed it using PIPP and AutoStakkert to create these images. Haven't done planetary imaging since, but I do hope to try it out again sometime soon. 

A photo captured from my balcony one evening showing earthshine on the moon. 

The rising moon captured using a telephoto lens without a tripod. 

My first attempt at capturing star trails. This is a single exposure taken over approximately 12 minutes. Photo taken at Lake Eildon. 

This is my first attempt to capture the Aurora. The pink glow is the Aurora Australis seen from the Southern Coast of Flinders. 

This picture shows the recent lunar eclipse- the blood moon, as seen from Flinders shortly after sunset on 8 November 2022.

Sky Observation at the Arthur C. Clarke Institute

After the first semester examination in our University, We were supposed to study 3 non technical modules-two of  which were compulsory and one of our own choice. The module I chose was Astronomy. The reasons for my choice were the interest I had in Astronomy, The interesting course contents and most importantly, The observation sessions.

We had two observation sessions at the Arthur C. Clarke Institute. One in the night for the observation of the Moon and the Planets and one session in the morning for observation of the Sun.
The telescope at the Arthur C. Clarke Institute, is the largest telescope in Sri Lanka. It is a Cassegrain Reflector type telescope and has a primary mirror of diameter 45cm. It uses an Equatorial Mount and is moved using computer controlled servo motors. It uses CCD cameras as the main imaging device.







It was unfortunate that the on the night we had our moon observation, the sky was very cloudy and not a single star could be seen. Also it was lightning. Because of this we couldn't use the Cassegrain reflector that night. Instead we used a much smaller reflector to look at the moon. The image of the moon was not clear due to the obstructing clouds.

The following day was better. We viewed the sun through the filtered Cassegrain telescope and saw two Sunspots. We also saw the Chromosphere of the Sun through an H-alpha filter.



The two sessions at the institute were very interesting and educational. It was a truly memorable experience.
