No not for this target. As I use a dual narrowband filter I‘ll always get OIII as well, but as you said in this case it just shows the normal continuum. I shot this data to combine it with RGB in the future, but I liked how M31 looks with just narrowband so I wanted to share anyway.
The equipment put together:
I couldn’t agree more, thank you for sharing so much information!
We were in exactly the same situation and bought a Fuji camera. We are very happy with our decision as we can shoot both ‘normal’ photography with the feeling of a nice camera body and astrophotography on a beginner level.
The results we got so far exceeded our expectations by far, we posted some of our images here in this sub or here in full resolution .
One thing to keep in mind is that normal cameras block most of the infrared light, which makes it unsuitable for shooting hydrogen nebulae. That’s a minor reason why we eventually chose a Fuji camera, as they filter a bit less infrared than other brands.
In the end the biggest impact makes the lens/telescope. After a lot of research we chose the Samyang/ Rokinon 135mm f2.0 lens. Also we found it very rewarding shooting with such a ‘small’ focal length because it forgives minor inaccuracies while giving very good results.
For us the biggest reasons for this hobby are to experience the night sky with our own equipment and learning very much (about physics, processing the data, cameras, …). Both things can be achieved with modest equipment and I would keep that in mind when comparing own images with others. Also I personally love the challenge to get the best possible results with things you already have.
Hope that helped a bit.
Also this is a 3d animation of our setup used to shoot this image:
I can recommend this online telescope simulator where you can simulate the field of view with your equipment. Your 300mm lens should be absolutely perfect
This lens is incredibly sharp and produces nearly no coma. Also the image is super flat and the lens also works for full frame cameras. For its high image quality it‘s also used by some more advanced astrophotographers.
As I bought it new for 400€ this was a no brainer because we can also use it for ‘normal’ photography.
I‘m sure your lens works well for many nebulae!
Thank you! Andromeda is way bigger than most people think. That’s the reason why it is a very (maybe the most) popular target for beginners. Also there went a lot of processing into the image, so don’t let the image deceive you from the actual conditions where I live (Bortle 5 zone)
The lens is the telescope in this case. But as the focal length of 135mm is fairly short it works best for objects appearing very large in the sky. Astrophotography can get very expensive very quickly, so we try to make the most out of the equipment we have. Just like with the 3d printed mount.
The Samyang 135mm f2.0. In some markets it‘s also called Rokinon
Thank you! I agree, it really is an amazing topic.
Glueing and screwing the parts:
One result shot with this mount (and many other accessories):
Very interesting, thank you for sharing. Your linked gif makes it very apparent that it was indeed a satellite.
I also searched in Stellarium and found a decommissioned military satellite called STSS Demo 2 that fits the path and time stamp perfectly.
-9 magnitude is insane, must’ve been a very cool sight.
Ha, thanks for letting me know. I didn’t know satellites can create flares like this. As all the other satellites were so dim I assumed it had to be something different.
For editing I chose the single sub with the flare and screen blended it in photoshop.
Beautiful, thanks for sharing!
Yes processing the image plays a huge role.
But at the end you can only work with the information provided by your equipment as there are physical limitations on what one can capture.
To me the most interesting part of this hobby is to learn what you physically really have to do to get good images. Physics not only plays a role on understanding what we see in these images but also on how to make them.
Truly fascinating!
Tl;DR The EU makes sure that third party developers gain access to connectivity features to develop devices like smartwatches, headphones or VR headsets that have a deep integration to the OS.
It is crucial that the request process is transparent, timely, and fair so that all developers have an effective and predictable path to interoperability and are enabled to innovate.
