One other thing I was interested to test out on the ASI1600MM-cool is its UV-imaging potential. This could be particularly useful bearing in mind its slightly larger sensor, for documenting the UV-pattern of flowers or of the human skin (bruises, sun-damage etc). I picked a Buttercup flower from my back garden and used this as my subject for testing its UV-imaging capability. Continue reading ZWO ASI1600MM-cool – UV imaging

The next test I wanted to do with the ZWO ASI1600MM-cool, was to test its gain settings and compare it with my back-lit CMOS ASI178MM-cool. Also, I thought I would post images taken in daylight (albeit using an Astronomik CLS-CCD filter) to show the amount of grain or noise at each gain setting up to Gain 500.

Over two months ago, I became aware that ZWO was coming up with a cooled larger sensor imaging camera which is even more suited to astrophotography. Obviously I was very keen to test out this camera, named ASI1600MM-cool. Courtesy of Zoltan from 365Astronomy, and Sam from ZWO, I have been given the privilege to test this camera out.

Heart nebula – Pixinsight processing

The next DSO that I worked on with Pixinsight was the Heart nebula. Previously I had only imaged this in H-alpha and O-III, but there was one session when I also managed to get some S-II subs as well. Hence it made sense to reprocess this with Pixinsight to see if I could extract even more out of the data. Continue reading Heart nebula – Pixinsight processing

In the past, I had organised quite a few birthday parties for my oldest daughter, with various different themes including Pokemon, Batman and others. Recently when my youngest daughter wanted to have a birthday play date with her best friend, I was tasked with finding the appropriate theme for her party. As most people love the Minions, it was a fairly easy choice to make – the hard part was sourcing the various different Minion-related things for the party. Continue reading Minion Birthday Party

Now that I’ve had the opportunity to do LRGB processing with Pixinsight, I have finally found enough courage to delve into narrowband processing with Pixinsight. Again there is much to learn in this new processing sequence, but as I’ve become fairly familiar with some of these processes, it is not as difficult as I imagined it would be.

Previously I had posted the image of Pleiades captured in LRGB and processed with StarTools. But I felt that I could probably do more with the data using Pixinsight. Having had a chance to learn the workflow for working with LRGB images, I decided to put the experience gained into reprocessing Pleiades. Continue reading Pleiades – reprocessing

Now that I have been able to use my obsy with the permanently mounted telescope, I was able on my second outing to grab enough subs of the Cigar Galaxy to process into an LRGB image. Continue reading M81 – Cigar Galaxy

A few weeks ago, I had very clear skies and I wanted to try some deep sky imaging using the Astronomik Deep Sky RGB filters. Unfortunately many of the DSO’s I wanted to image were too low down in the sky to image successfully. Hence I thought I would try imaging one of the not too small galaxies in widefield – the M101 Pinwheel Galaxy. Continue reading M101 – Pinwheel Galaxy (widefield)

Previously when my wife took up running and regular exercise and wanted to get a fitness tracker, I did suggest getting one of the more expensive models. But as she was not sure whether she would have a sustained interest in this, she decided that getting the less expensive Riversong fitness tracker would suffice. But now that she is really getting into running and exercise, she finally decided that there were some features that were essential to have in such a tracker. Hence she decided to buy the Fitbit Surge. Continue reading Fitbit Surge Fitness tracker with continuous heart rate monitoring
