The other recordings just weren’t anywhere as useful.Īnyway by far my best Jupiter this season, and I’m quite pleased with the result. I had recorded for several hours at a time, but in the end I combined only the best 4 red channels, and 2 green and blue channels each, that all happened to be imaged within about a 25 minute time period of more stable conditions.
But it does take forever though. The seeing wasn’t that great really, I only stacked about 30-40% of the frames for each recording, but the transparency was good and being able to use this many stacks really helps to bring out the finer details and contrasts. I like this semi-manual approach, as it gives you lots of control, and involves lots of fiddling around with image processing software. For this image I let WinJUPOS derotate each slightly sharpened stack I had selected to the same reference, and then I manually recombined all of those again in Photoshop, taking only the best (parts of) each stack. Processing this image all in all took about 5 hours, as I wanted to combine as many images as I could using WinJUPOS. After half an hour into imaging I had to rush back inside and fix some manual declination controls I added just hours before the recording session started – basically I had to apply a bit of lock bond to make sure the bolt stayed fixed when I turned the declination control – but other than that I had everything I wanted: decent tracking capabilities and a possibility to correct for my poor polar alignment. I had been without an equatorial platform for my Dobson for a few weeks, but I was just in time to have a new platform more or less in working condition.

Registax (by Cor Berrevoets) offers the best lunar and planetary results in a very easy to use package. The package that emerged head and shoulders above the compors was written by a Dutchman, Cor Berrevoets and is called Registax.
RegiStax has been written and compiled to run under Microsoft Windows, but RegiStax can be run under Linux via wine.
