Quote:Hi,I’m just getting started in planetary and lunar imaging and would appreciate some advice on choosing a camera to use with my Celestron 8inch SCT. I know that the 8 inch is probably the minimum aperture worth considering but I thought I’d start out with that because it’s more suited to my current observing situation, is easy to set up and will probably get used more often than a larger scope.
Quote:Though the NexImage 5 seems like an economical camera to start with, I’ve seen a lot for sale in the astro classifieds. The DFK21 seems to be used by a lot of people, so am I correct in assuming that it would be a better starting place than the NexImage 5?

Quote:Thanks to all of you for your recommendations. I really appreciate it. I’ve also looked at all the images you provided links to and I’m blown away by the quality of what you all have been able to achieve. If I can eventually get results that are half as good, I’ll be happy! I hadn’t considered the ZWO ASI120MC before and after looking at their website, I seems like it would be a great choice to get started with. I also noted Steve’s comments about the NexImage 5. That raises a question when comparing the NexImage 5 and the ASI120MC (which will probably show my lack of understanding of what camera specs are important!). The NexImage is quoted at 5MP with a pixel size of 2.2 microns, whereas the ASI120MC is only 1.2MP and a pixel size of 3.75 micron. Applying conventional photography logic, I would assume the NexImage would be capable of capturing finer detail. However, it can’t be as simple as this, otherwise everyone would be using the NexImage! The other difference between the two cameras that appears significant is that that the ASI120MC is capable of capturing at a much higher frame rate, especially at its highest resolution. Any clarification you can offer of the important of the resolution compared to frame rate would be helpful in making a final camera choice.John

Quote: For Saturn though there is no point in faster frame rates because the exposure needs to be much greater on Saturn.
