Latest Solar Prominence Animations

Filed under: Animations, Software, Sun — Dave @ 12:50 pm

I was lucky to record 4 hours of unbroken solar activity during Scotland’s recent record breaking sunshine. DSSR guided my Nexstar 4SE/PST combo while it also captured 20s videos with 20s pauses between. These videos were processed in AviStack and DVS was then used to stablize the animations and add the overlay text and scale Earth.

This was the first ‘blind’ test of DFM and I relied totally on the focus meter to adjst focus. I made 3 animations from the data which are below. (right-click on videos to turn on looping) (more…)

Fantastic Mars Animation

Filed under: Animations, Software — Dave @ 11:50 am

DVS user Sylvain Weiller recently capture a few hundred thousand frames of Mars. Unfortunately, he did not use DSSR’s autoguider during capture so the planet’s disk was moving around a lot during the sequence. We worked with Sylvain to allow DVS to handle huge image sets like his and these new features are detailed in the latest manual in the support page. (more…)

Jupiter Twin Moon and Shadow Transit Animation

Filed under: Animations, Software — Dave @ 4:27 pm

This was taken with a Nexstar 4SE OTA on a HEQ5 Pro mount and a Toucam webcam. DSSR autoguided the scope and captured the videos. Seeing deteriorated towards the end but DSSR never lost the guide target over 5.5 hours.

Latest Testers’ Gallery

Filed under: Moon, Software, Sun — Dave @ 11:08 am

Our illustrious test team have been busy trying out the new mosaic feature of DSSR. Below are a few of their images. This is the best part of my job – looking through these great images on a large TV. It doesn’t get much better.

Click on an image to see the original – some are VERY large.

Gain v Image Quality on Solar Images – Results

Filed under: Software, Sun — Dave @ 3:26 pm

Tester Mike has created a batch of 8 solar images to compare the effects of gain, shutter speed and frame rate on solar image quality. He then offered them up to the test team to pick their favourite image and the results were very interesting. The images are shown below and the exposure settings are at bottom.

High Dynamic Range (HDR) Solar Mosaic Capture

Filed under: Software, Sun — Dave @ 6:17 pm

Today we were lucky to have some Sun and try out the MultiExposure feature of DSSR on a solar mosaic. DSSR allows you to take a series of videos at different exposure settings to cover the full range of features on the Sun. These can range from the brightest flares to the faintest prominences.

We set up a Coronado PST with an Imaging Source DMK21 at prime focus (more…)
