I must have missed this one. Looks really great. I never tire of this neb and that is why I use it as a test object. You will find the Canon 1.4X produces as good an image as the original lens or very close to it. You have to pixel peep to see the very slight difference. The Canon 2X does not at least for stellar images or very bright contrast as it introduces very slight CA and amplifies the CA of the lens.
This zoom should give you years of flawless service. Any L lens is highly weather resistant and dust sealed. This is very important with a zoom as some can pump in the dust as they zoom.
Again a wonderful deep image as I can see faint nebulosity that an unmodded camera should not normally record unless you have dark skies.

Thanks Bert,
My skies in Hahndorf are quite dark - not pitch black by any means. A couple of these subs (3 I think) were taken with the moon shining through the trees too, so I think I have invested in a winner with this mini setup.
The short FL also hides the EQ5's tracking flaws nicely!
The lens isn't huge on my side by side plate either - a small footprint, weight-wise.
Do you use the Canon Lens clamp/tripod mount Doug? Or do you find the setup is sturdy enough just mounted from the camera?
Dave
I use the generic ebay "For Canon" tripod collar. It's a little snug on the lens so that the lock doesn't fully screw flush, but is still rock solid on the mount. ($20 v's $120 for genuine Canon model)
I bought one of these from Bintel to attach the collar, camera and lens to the dovetail of the side by side plate... https://www.bintelshop.com.au/Images/Stock/7734X.jpg
I tried the Camera attached to this (no collar) with a smaller lens and it was reassuringly solid also.
Do you use the lens hood when shooting?
I highly recommend you use it at all times.
Also helps with the dew.
Also I'd recommend a clear filter for the lens to protect the front element at all times.
I use a good quality Hoya UV filter.
Keep up the good work.
Yes Andrew,
I use the lens hood, but I sold my hoya UV filter to sweeten the sale of my 17-85mm kit lens
I could do with it now - I treat the lenses very carefully but accidents are accidents after all!
Doug
If you leave the lens hood on when moving it will protect the front element from 'accidents'. Unless your UV filter is optically near flat/parallel it it will lower the lenses performance.
