Don't forget to remove the adapter and screw an extension onto the cc.

I'm still trying to get rid of some residual coma in my images and the CC could be the cause. Do you mean this ring:

Not just the ring. The adapter as well. You'll see two slots in the M42 thread. Use the blade of a knife to unscrew it:

On newer batches, the M42 connection was just about workable, but we'd still recommend losing it and going with m48.

Suerte.

Hi again everyone,

so managed to get home from university to get a look to my gear. How do I unscrew this T2 thread for the coma corrector and add my extension?

[alacant]

Use the blade of a -blunt- knife in the two slots in the M42 thread.

[Oisinmcc16]

So where  are the two slots? 

[Oisinmcc16]

Got it. No worries. Thanks for the help

I feel so silly here… can’t seem to figure out where to screw the extension into

The end of the corrector from which you just removed the adapter has a m48 male thread; there.

So the spacer I bought was the baader one the recommended… I’m worried it requires this stupid Canon EOS protector T Ring thing. https://www.firstlightoptics.com/adapters/baader-protective-t-ring-for-canon-eos.html

the spacer

Spacer? You need a simple 4mm or 5mm m48 extension ring and your m48 adapter. That's it.

This one would be fine:

Which do you have? Post a photo?

Ffs I’ve looked it up and this wasn’t needed at all. 
 

The lack of information on Baader’s behalf is appalling. 
 

Really confused on what I need now… just want to get out with this new tube 

[alacant]

Don't overthink it;)

The only extra item you need is in this post.
