Nightly imaging session can gather hundreds of gigabytes of data so aim for a 512GB or larger storage device. Currently, M.2 NVME drives are the fastest. I would recommend against using a mechanical hard disk (spinner), which can be too slow. Planetary capture is extremely data and speed intensive. You will need a computer with a USB 3.0 port. A laptop might be used for imaging in the field, with a more powerful desktop used for data processing later. Not much detail is visible without processing to bring out the details we’ve captured. Atmospheric turbulence varies, so using data only when it is lowest gives us the best possible results. Not having access to adaptive optics as professional observatories do, the main weapon in our arsenal is “lucky imaging”, a technique that allows us to take advantage of the moments when the atmosphere happens to be relatively still. To achieve the maximum possible resolution, we have to try to reduce the effects of the atmosphere, or at least identify times when it is least degrading to the image. You might need to clean up your movie through PIPP if autostakkert isn’t working and then try autostakkert again.The actual theoretical resolution of a telescope is a lot higher than we can usually record through the atmosphere, especially with larger reflectors. Tis basically great but data that isn’t great can be quite hard to stack. I’ve used Sequator for some of my widefield milky way shots and timelapses.įor planetary and lunar and solar stacking I use Autostakkert. I find it is essential for more complicated projects. Pixinsight is extremely powerful but very geeky. Apparently Sequator handles colour data very well too but looses out over DSS in terms of sharpness. However I also use Pixinsight to stack OSC data (aka colour data) because Gary Palmer told me that Pixinsight handles colour data with all its annoying bayer patterns better than both APP and DSS. APP is also brilliant at mosaics and very useful when stacking the multitude of stacked images produced by different scopes from the BAT. It is simply the easiest and quickest to use. I started out using DSS but now use APP for most of my stacking.
