Let's explore using a 75-300mm lens for astrophotography. We'll focus on capturing the Orion Nebula, Flame Nebula, and Horsehead Nebula during a night of stargazing from my backyard.

After waiting for clear skies, I'll guide you through the equipment I'm using, including the Canon EOS 2000D, the 75-300mm lens, the HEQ5 Pro GOTO mount, and the ASIair Pro.

As night falls, we'll start a 6-hour exposure, and the next day, I'll share the individual frames and the final image. It's the best way to see if the lens is good for astrophotography.

Over two clear nights, I managed a total of 6 hours of exposure, dealing with wind.

I experimented with different apertures - F7.1 and F5.6 - to overcome challenges like chromatic aberration and star halos. The final image, with 2.5 hours at F7.1 and 3.5 hours at F5.6, shows stars without halos, even though some details might be missing due to aperture choices.

While the image might lack some details, I plan to get more exposure time in the coming weeks. If you enjoyed the journey, consider subscribing, liking, or leaving a comment. Thanks for joining me, and stay tuned for more stargazing adventures!
