    Thank you for your comments. So, if you had to choose 7"mak over the 9.25" sct for planetary and double stars, which would you go for? I'm aware of aperture is king rule. If both were in your garage or wherever you keep scopes, which one would you reach for, if the planets were out? Or you wanted to have a go at e f stars in trap or the pup? 

    For planets I'd go for the C9.25 - it's what it's made for, especially imaging. Look up Damian Peach's images taken with a C9.25. Maybe he has used ideal seeing conditions but it still shows what the scope is made of.

    If I was doing doubles only, probably a 180 Mak. The tighter stars and better contrast would make the difference.

    I've not used a 180 Mak, only a 140. That couldn't see the pup but the C9.25 shows it easily - e and f in the trap are easy too, as they were in the 250 Newt.

  2. I went from a 10" Newt to a C9.25. There are differences; the Newt had more contrast but the C9.25 is more easy to handle, collimates better and is easier to push to higher magnification.

    While not having the tight stars of a frac or a Mak, the C9.25 splits really close doubles easily. Something like an 0.7" double is a wide split.

    If you think they take long to cool down then you are keeping them in the wrong place!

    The person who is truly happy  with their telescope(s) choice will not feel the need to constantly justify it, and cares nothing for what other people think, and don't lay awake at night worrying about that not everyone wants to use the same telescope that they use.  They will be far too busy observing, when it's clear.

    The happiest bunnies are the quiet bunnies who just get on with it

    Indeed. I feel there's also a lot of wishful thinking going on here. 100mm is 100mm no matter what spin you put on it. You canna change the laws of physics as an erudite colleague once said :wink2:

  4. Exacly what I said above.

    The reality here is Skywatcher have said this bolt is made from soft steel for a reason. It's so the bolt thread strips rather than the mount thread which is more difficult to fix/replace. Bolts are bending because people are not following the manufacturer's instructions. Those of us who do follow the instructions don't have a problem. I've had huge amounts of kit on mine and the bolt is fine.

  5. I tell you what I do with my HEQ6. I adjust it when fully loaded. What I do is unwind the locking bolt put my weight on the counterweight bar; now there is no weight on the adjustment bolt I wind that in until it's over compensated; I then take weight off the bar and unwind the adjustment bolt until it's just above where I want it to be; I then wind in the locking bolt which when tightened moves the mount the last fraction of a millimetre until the axis is aligned.

    I've had my HEQ6 since they first came out and have had no problems with the adjustment bolt.

  6. Sunday night looks clear so the Variable Star workshop is looking good. Everyone welcome :hello2: You'll get guidance first hand on observing variables using the scope I use.
    The morning session covers all the practical and science stuff. Do you know how many types of variables there are? Variables help us understand the science of stellar evolution from birth to grave :ohmy: There'll be practical stuff like how to read variable star charts; how to record observations; making magnitude estimates; understanding Julian dates and all the other wibbly-wobbly timey-wimey stuff!
