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: http://wp.me/P1dpnD-61

New Astrometry Module for DVS

Filed under: Software, Tutorials — Dave @ 12:09 pm

DVS now has a new Astrometry module that allows you to measure the movement of an object between a pair of images. You can use this to calculate velocities of asteroids, comets, minor planets, satellites, etc. It can also be used to measure object parallax angle during transits such as the 2012 Venus transit.

Successful trial of AzTrak!

Filed under: Software — Dave @ 12:46 pm

I know there are a lot of users waiting for DSSR to be able to autoguide Alt-Az scopes using AzTrak. The good news is that the DSSR test version now has a working version of AzTrak which is accurate enough for Solar System targets.

AzTrak autoguided on a sunspot with a Celestron Nexstar 4SE for several hours yesterday and we are currently fine tuning the AzTrak algorithms to improve accuracy. We hope to release AzTrak very soon.

Here are some sunspot videos made with AzTrak

Sunspot AR1471 6th May 2012 6:21:10 to 6:45:34 (UT)
