@thomasfuchs Can light pollution just be canceled out by more exposure time? Or is the software doing that? Also, what exposure time are you using per frame? I am interested in the accuracy the ZWO mount you are using.

@thomasfuchs That looks amazing, especially the dark parts of the nebulae (or is it dust?) Whats the Bortle value of the location you shoot the pictures at? Or is light pollution not a problem for you because you use a filter wheel?

@thomasfuchs @hendric @jdlbt @raspberryswirl Removing the IR filter will make the camera unsuitable for normal photography usage and my dad still uses the camera for that. I am aware that there are ways to make it clip-on but I don't want to risk breaking the camera.

@thomasfuchs @hendric @jdlbt @raspberryswirl And regarding the astro camera: Is there a significant difference? I read that filters in cameras get rid of most of the primary emission line of hydrogen, making nebulae much darker.

@thomasfuchs @hendric @jdlbt Oh wow, I thought you need a way longer focal length to capture that much detail! Is there a particular star tracker you can recommend? Although @raspberryswirl's suggested DIY star tracker makes me want to make my own, but I did some calculations and getting enough accuracy might be a challenge.
Camera lenses with high focal lengths seem to be expensive, is there a specific refractor you can recommend?

I am interested in #astrophotography but my current equipment is quite limited; I have my dad's Canon EOS 5D Mark III (which is defintively a good camera) with a 135mm camera lens as well as a 90/1000 Omegon achromatic refractor telescope on a quite flimsy equatorial mount without goto or automated tracking.
I am considering getting a better telescope but I have no idea where to start. Are there some telescopes you can recommend I won't have to spend a fortune on?

@jdlbt I started with astrophotography about a year ago with the 135mm lens and made ~150 pictures of the Orion Nebula which I stacked in Siril. The reason I want to use a telescope is that with my current setup the Orion Nebula is only around 300x300 pixels.

The scopes you suggest are quite expensive, wouldn't just buying a telescope with goto and autoguiding yield bigger and better pictures? Especially Maksutov telescopes seem cheap and have a large focal length and aperture.
