I really enjoy astrophotography and would like to move to the next level. I'm mainly after beautiful nebula. Heres what I currently use:
Canon EOS R (stock). RF15-35 2.8, EF 100 2.8, Sigma 150-600 5-6.3. I mainly use the 150-600 for DSO's.
Star Adventurer which gets me around 30-45 seconds at 600mm and longer for the shorter focal lengths.
Basic timer that allows me to program as many shots as I want for whatever duration I want.
So far this has been a lot of fun and really served me well but I'm wanting more. I have a few limiting factors. My budget will probably be ideally $800 right now, but can stretch it to $1200 if absolutely necessary meaning itll make a big difference in my results over what I have now. The other limiting factors are time and light pollution. I'm not in a big city, but I'm not in the country either. So on those light pollution charts I'm yellowish green. As for time I dont have all night for automated sessions. Usually just a few hours per night. So I've been debating between a better tracker which will allow longer exposures with autoguiding? But also considering a color or monochrome dedicated camera to replace the EOS R for this. I can only do one or the other. So what do you think would yield better results? A dedicated astro camera for the 150-600 lens or better mount for longer exposures on my current setup? I feel like the second option will be limiting because of the light pollution. If I go with a monochrome camera will 3hrs a night and 30-45 sec exposures be enough to get an image? Guess I could always do different filters different nights. Open for ideas on this! Thanks!
