If you do have under-sampled images to play around with, the fun can begin. I still have some recordings left to process from the night before, and I’m really curious to see the changes in the results from one day to the next as the clouds on Mars can be pretty dynamic!For this recording I used the ASI120MM monochrome camera (as usual) and some Baader color filters. Combine this with an accurate estimation of the location of the features throughout the image, and you can end up with a lot more resolution than you started with even when the field of view is changing.Apart from making Hubble images sharper, Super Resolution is also applied to telescopes actually peaking down to earth. No, I’m not going to use GPGPU (yet? Post-processing with Photoshop and WinJUPOS, to derotate the stacks.Occasionally, I’m going to use this blog to show some of the images I made. Donc allons voir ça de plus près !Bon, vous connaissez tous ce logiciel ? For most planetary recordings there simply is little to gain by drizzling.Instead of just presenting a new and unfinished AutoStakkert!2 version – remember that I said it would be released AROUND the end of August – I thought it might be nice to start keeping a small log here to keep you up-to-date with what I’m actually working on.I still have a long list of new features and bugfixes to implement. I was not going to waste this opportunity by just staring at Jupiter through an eyepiece.
Son site est en français et tout y est clairement expliqué, je vous invite à y faire un tour si ça vous intéresse !J’aurais pu le mettre dans la première liste des logiciels gratuits, mais il n’est pas nécessairement utile donc je n’ai pas voulu alourdir la panoplie. I know that some of these are more important than others, but somehow I always start implementing those ideas that I enjoy working on the most. Il vous renseigne sur le nom des astres ainsi que sur leur distance par rapport à …
Stacking the images would certainly increase the signal to noise ratio, and you can even reject frames that are too blurry or compensate for the movement a bit, but you will never be able to go beyond the diffraction limit of the optics.

Getting a speed boost of 5% is nice, but if I need to put in a lot of hours that could be spend on new functionality it would hardly be worth the effort. This way I can see many more details, and share the image with other people as well. You will need a larger aperture to get more detail.If you can’t determine the offset of the target in the image, then even if it did contain extra information, we wouldn’t know where to place it! 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.Processing this image all in all took about 5 hours, as I wanted to combine as many images as I could using WinJUPOS.
