Autoguiding Celestron and Skywatcher Alt-Az Mounts

Filed under: Animations, Software, Sun — Dave @ 10:44 am

DSSR now has the ability to autoguide certain brands of alt-az mounts to allow you to track and record the Sun, Moon, planets, comets, etc.

The guider can guide your mount to within 2 or 3 pixels which is good enough for solar system work. Below are some solar animations that were captured on a Coronado PST on a NexStar 4SE mount.

DVS updated for easier cropping and overlays

Filed under: Animations, Software — Dave @ 10:41 am
Hi Folks,
DVS should automatically update itself the next time you run it.
The crop routine has been changed to allow for easier crop adjustments and you can also preview with the cropped area blanked out. This makes it easier to spot rogue bright borders.
The overlay routine now allows for easier and more precise positioning of overlays.
The changes are documented in the DVS manual which is available here:

Adding Time Stamps to Animations with DVS

Filed under: Animations, Software, Tutorials — Dave @ 10:25 am

DVS now allows you to display time stamps on each frame of your animations for an accurate display of capture time. DVS can read the capture times directly from DSSR images or you can simply set the start and end times for your animation. Prefixes and suffixes can also be added to the time stamp. The relevant section from the DVS manual is copied below: (more…)

This tutorial was produced to show the work flow involved in creating these solar animations.

You can download a zipped folder of solar Fits files to try out from here (190mb). Go direct to step 4 if you download them. Alternatively, you can download the complete set of processed PNGs here (59mb) and go directly to step 5. (more…)

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…)

From Robert,

Taken with Coronado SolarMaxII 60mm with BF15, Meade 3x Barlow, DMK41AU02, Celestron CGEM mount, captured as 20s clips with 40s delay using DSSR, processed in Registax 5, aligned and cropped using DVS. (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.

September Testers’ Gallery

Filed under: Animations, Software, Sun — Dave @ 8:29 am

Our testers have produced a fantastic collection of images and animations which are presented below. On most of the videos, you can right-click and turn on looping which makes it easier to observe the fine detail. (more…)

Overnight Jupiter Autoguide using DSSR

Filed under: Animations, Software — Dave @ 8:21 am

We set a new DSSR autoguide record recently. I set up my scope on Jupiter at 10pm and went to bed. When I woke up at 4.20am I was very pleased to see that DSSR had successfully tracked on Jupiter the whole night. It only lost track when Jupiter went behind my roof. (more…)
