Hello! 

New to Astrobin! I live in Sweden and have just recently fulfilled my childhood dream of getting into astronomy and would like to get into astrophotography. 

I just received my WO Redcat 51 today along with their standard camera adapter M48 compatible with Canon EOS. 

The adapter wont fit my camera; an Canon EOS RP. I figure i have got the wrong adapter but which one is the right one? 

I suppose the answer is out there somewhere, please enlighten me : ) 

Best regards 

Daniel

Hi Daniel,
I'll be honest, I'm not sure which adapter you should be using. I have a ZWO ASI1600MM Pro.
I was using a DSLR years ago but struggled with it. The cooled camera I'm using now gets amazing images. If you can afford one, I would encourage it.
With that said, there are many people out there shooting great images with DSLR cameras. They may be able to help you.

Hello, if I'm not mistaken the adapter you need is this one:

You might be able to use the RF-EF adapter by Canon with your current WO adapter instead, which would allow you to use EF lenses for everyday photography.

Hope this helps.

I believe the standard adapter is for DSLR. Mirrorless cameras like the Canon R series are slimmer and as a result would require different adapters to have the correct 55m back focus. I believe this part is what you are looking for

The adapter you have posted for the older EOS EF style mount ie Mirrored DSLR’s. You need one that fits the new Canon EOS -R mirrorless brand. The typical sellers have an M48 adapter for it.

Rp it's a miroirless so you have to have the adaptor from Rf to Ef to fit with the M48

I don't have one, but it looks like your camera uses the RF mount which this adapter would support https://agenaastro.com/william-optics-48mm-t-ring-for-canon-eos-r-mirrorless-camera.html

The Canon EOS RP uses a different connector (Canon RF lens mount) than the standard Canon EOS connector. From what I can see, you have two options here:
  • Either find a M48mm to Canon RF adapter to replace your current adapter
  • I believe Canon also has som EOS R mount adapter that allows it to mount older EF and EF-S lenses. It's possible that this adapter would allow you to mount your Canon EOS - M48 adapter. I would go to a shop to actually test it out.

Depending on where you bought the Redcat 51, it might be possible to talk to the shop and find a solution with them (some shops have good customer service, some don't...).

I hope this doesn't deter you from making your first steps into astrophotography (I remember the whole adapter-thing was the biggest frustration point for me, when I started). The Redcat 51 is a perfect starter lens. You can go for some of the bigger galaxies (Andromeda is a good start) or a wide array of nebula (Orion, Horsehead / Flame, Seagull, North American, Jellyfish, Heart & Soul, Veil, Rosette, ...). If you don't have it yet, a good Tripod and a Star Tracker would be the next investment.

Hey Brimborium!

Thanks for your post and suggestions! 

I have read all the replies and have gone for several solutions (just to be sure). I bought a T2 to M48 adapter for my Baader Wide T-ring D52 Canon R (which fits my camera but not the telescope). According to the vendor Astroshop, this will do the trick. On top of that i bought an adapter for the camera to be able to connect to the older EF-lenses. That way i will hopefully be able to use the William Optics adapter as is. Just to finish it of i purchased another adapter which im not so sure of. It was a rage buy ; ) 

This (and a few other glitches) will not deter me from taking a photo of the sky. I am willing to pour any money and time into getting that picture : ) It really doesnt matter how the first picture turn out to be... it just has to be. I knew astrophotography is a rabbit hole and an artform where you have to be somewhat technically skilled (which im not) but it will be done. In one way or the other. 

Seeing a few pictures here and a few videos on youtube i felt that WO Redcat 51 mm would be a fine entry level equipment to get into to the hobby with the least amount of trouble. I looked at Skywatchers Evolux 62 mm and WO 61 mm doublet but they fell a bit short of the cat due to the design and low weight (i like to travel and would like to be able to bring the equipment if i fly somewhere). When it comes to the mounts i have the Staradventurer GTi and EQM-35 pro. Hopefully those will be good enough for short exposures.

Sometimes it hard not to! But it feels so much sweeter when you finally fix the problem (and move on to the next ; )
