![]() It can become a major issue on warm summer nights (this is one of the reasons I’m moving from the Canon Rebel T3i to the 7D Mark II). Thermal noise is less of an issue in the winter, on cold nights. (The 7D Mark II exhibits the lowest thermal sensitivity of the cameras he has tested to date.) Roger Clark has tested a number of Canon cameras over the years, and found the thermal sensitivity to be generally decreasing with the newer generation cameras. Some sensors and cameras though are less susceptible to this thermal noise than others. This is because of the fact that as the temperature of a CMOS or CCD sensor increases, so does the thermal noise recorded by the sensor. Professional astronomical cameras are actively cooled down to temperatures well below freezing. (Of course, I just bought a new camera that doesn’t have this feature, so apparently I need to start doing yoga.) Low Thermal Sensitivity Otherwise as you image higher in the sky, you’ll be bending further and further down while craning your neck to view the screen. Variable-angle LCDĪ rotatable LCD that you can orient independently from the camera can be very handy when centering a star and focusing. ![]() A live view that also includes exposure compensation can also be handy in making sure your camera settings (ISO, shutter speed) are reasonably appropriate for bright targets like the Moon, Jupiter, and Saturn. Having a live view makes it easy to center and focus on bright objects. DSLR Astrophotography FeaturesĬharacteristics you should look for in a DSLR you want to use for Astrophotography. If you’re looking for a new camera, here are some aspects to think about, followed by some recommended models for different budgets. So if you already have a DSLR and want to get started with AP, go ahead and use your existing camera. ![]() Probably not in the next release as I'd like to get that out relatively soon, but perhaps in the release after that when I have more time to do the coding.If you are looking to buy a new DSLR for Astrophotography, this article offers some recommended cameras and some of the features to look for in an astrophotography DSLR.ĪNY relatively modern DSLR will work for astrophotography, and work pretty well. I will add alignment in the live stacking for oalive. All they'd really need to do would be to make the files available easily from their website (they didn't used to, but to be fair I've not checked very recently) and have some arrangement for reporting bugs. It seems a bit haphazard to me though, and I don't really understand why it should be. When I get time I'm going to try a combo of Oacapture to output FITS files and ALS to read the output folder and align and stack the images. Oacapture looks good, Oalive also but doesn't support alignment in Live stacking. Don't think the sdk materialised though so will follow up with them again. ![]() They were working on a Mac SDK, and I was hopinh that it could get included in Firecapture which seems to have what I want in a Mac compatible tool. I know Mac isn't high priority for Altair having discussed with them via Facebook. After a frustrating session last night with the camera disconnecting every time I went near it I'm back to considering Mac options. I tried a few different tools but finally resorted to using the family Windows laptop with dodgy USB. ![]()
