Okay I have been out and tested the scope I took a photo with my DSLR, the chromatic aberration is very bad in photos but not bad at all using an eyepiece can this be explained?

Even a std DSLR will have much more sensitivity to the extreme red and violet ends of the spectrum compared to the human eye so this might explain this CA.

This is a 120mm refractor we are discussing. In this case the objective will need to be removed and the elements split because cleaning fluid from a previous clean has seeped between the lens elements

Attempting to improve the cosmetic appearance from something that is going to have no affect on the performance is a slippery slope and could result in circumstances that could have a significant impa

I don't think that Steve offers this service any more.  You could try Rother Valley Optics, I know that they offer a collimation service, not sure about cleaning. John

Plus you can pickup a Minus Violet filter (fringe killer) if it really bothers you. That said I agree with John. That scope with the EQ3-2 with perfect optics would have been fair for £125. That said when you find the confidence you could remove the cell and perform a full clean (you have to mark everything on the edge on lens's - I've done this before).

to be honest I agree with the others for now though.. just leave it. The only thing I would do is check the collimation. Its a skill that you need going forward.

Good Luck
