Hi @Skipper BillyI just measured the screw holes in the foot of the mount...looks like they are separated by 3.6cm, shorter than my long vixen dovetail. Hi there @Philip R do you know if the two holes in the medium Vixen dovetail match with the mounting foot (separated by 3.6cm)? Thanks for all your help!

Thanks for the replies, I do have a spare vixen dovetail and I can run a screw through one of the holes but the spacing is different on the lens foot so I can only get one screw in. I may have to drill a new hole through the dovetail bar to get this to work...

Hi there everyone, I was recently loaned a long telephoto lens (Canon EF 500mm F4), it's a fantastic lens and I really want to do some AP with it but I am not sure what's the best way to mount it. I have a AZ EQ6 mount with an ADM Side-by-side bar which accepts both Vixen and Losmandy dovetails. Does anyone know of a solution. Here's a couple of photos: The mounting bar currently attached to the lens foot is too wide for a Vixen attachment bar and too narrow for a Losmandy. Thanks everyone Dan

Nice result! I got a similar view with my Skymax 150. I want to go out again soon and capture the crescent thinning! Dan

Really good timelapse, nicely done. Interesting when the street light turns off you see the sky glow and then the flood light turns on next door; sort of a rock and a hard place. Even so, your sky looks great overhead.

Just come in from a session imaging Venus, such a beautiful sleek crescent. I think i am falling back in love with my Mak 150!

Really nice view! Nicely done.

The light hitting my camera was almost half a billion years old! Quite unbelievable really...

There is a very faint elliptical galaxy just below and to the right of the star I labelled...it could be that.

Interesting...Thanks for the reply Waddensky. 6.3% of NGC objects are single stars or not locatable! That's a lot!

I almost forgot I had this one. Its a copy of the 'New Popular Star Atlas' from 1974.

A silly topic, but it has been bugging me for a few days... I was looking at all the named objects in the area around M13 and I noticed NGC 6199 shown as a Dark Nebula. On Google, it is shown as a single star...I don't see how these objects made it into the NGC (I assume there must be other objects like it in the NGC). Was it compiled more like a historical list before people really knew what the objects were?
