My Astrophotography Activities

Upgrade to AMD Ryzen Threadripper 1950X 16 Core Processor

Yes I upgraded my desktop that I primarily use for processing my astrophotos and did a little bit of PixInsight benchmark and here are the results.

UPDATE

While doing a lot of performance optimization to my rig, I noticed some slow performance and wasn’t really happy with it so I decided to do a clean install once again.  We’ll this time the rig is more stable and the recent results for the PixInsight benchmark proved my findings.  With a gain of 3,713 points of the total performance score with a little bit of a tweak and installing the system on the M2 drive proved it’s worth effort.

The California Nebula

The California Nebula

Taken under two hours of total integration time and yet was able to come up with a very good detail of the nebulosity.  Also this was a quick and dirty processing, nothing special in PinInsight and not even processed in Photoshop.  All was done with this image is just a simple PixelMath for combining the images from Ha and S2 filter data.  Will update this post as I’m still collecting data.

Testing the Tamron 18-400mm F/3.5-6.3 Di II VC HLD

I recently purchased the Tamron 18-400mm F/3.5-6.3 Di II VC HLD lens for my canon.  I tested it using the SL1 and 7D that has the cropped sensor.  I was amazed with the result and it’s truly at 22.2x zoom.

The images above are not processed, no correction, without any filter, etc.  This is just a demonstration of the zoom capability of the lens.  All shots are handheld with only the VC turned On.
