Astrophotography with a 75-300mm lens: Orion constellation
5,877
Published 2024-01-16
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!

Nebula looks insanely good.Thanks for posting incredeble image.

A very nice image, Felix, and well worth stopping down to f/7.1. Great video and thanks for sharing. ๐

Amazing Video

Always enthusiastic, greetings from Indonesia ๐

Awesome vid, mate !

Well done man! just got into astronomy in general and I love that you can capture stuff like this with just a zoomlens and a DSLR ( and a star tracking mount, but hey :) )

I started with that very lens and a Canon 600D, but my results weren't as good of yours as I didn't know how to use it properly. I wish I had seen your video back then. These days I tend to use a Samyang 135 f2 lens for wide field photoraphy, but for anyone on a tight budget the Canon 75-300 will get you going.

Very nice image

This lense is ok-ish and will lead to one thing: you replace it with a small telescope or a better lense soon. But its fun to take photos with such lenses. You can still get good photos but i would recommend get a better one. I started 2 years ago with a 135mm 40-50 year old Zeiss Sonnar.

So weird how they rate aperture as a ratio between itself and focal length.
-
Hey man nice videos i just have one question, did you set your f stop to f7.1 at 135mm? And what should i stop it down to at 300mm since there is still coma at that focal legnth
-
Damn, your english is very good

I great video man! I am still messing around with my settings as my images just seem too bright. Same lense 75-300 using @300mm, iso 1800 f7.1 40seconds exposure Canon 1100D. My sky is brightness 4-5 so that may just be the light pollution. Does this brightness matter if the starts are still visible for the stacking software, persumably the brighter the image / sky, the worse the nebulosity? I do plan on buying ASTRO-TECH AT72EDII with a light filter but want to get at least somewhat decent with just the camera before investing further.

This lens is good but I found a lot chromatic abbreviations and fringes at 300mm.
-
Nice work! Which software do you use to process such images?
-
Bro can u do a video how to capture orion without tracking and how to process images

Thanks for this video. I have this lens, and in many respects it's a poor lens for astrophotography... UNTIL... ...Until you step it down, as you suggest. When fully open the colour fringing, halos and coma aberration is awful at almost any focal length. I'm motivated now to go out and shoot again with this lens at around 135mm and stepped down as far as 7.1 I also have the Rokinon/Samyang 135mm f/2 so it will be interesting to comapre the 2. The Samyang is good, but is also about 3.5x the price! Thanks again, and clear skies!

What did you use to process this?
