  1. So pleased for you, being able to see properly is something we all take for granted until things start to go wrong.
    Like several posters above I've been told eventually I'll need an operation. At my last eye test I asked the optician to speculate how long before he would recommend the operation and was told at least five years. I don't notice a problem at present.

  2. Obviously I'm not aware of the car you have but in most cars transporting a dob isn't a problem. Wrap the tube in an old blanket/duvet or similar and wedge it securely in the boot/on the back seat, the base will sit comfortably on the front seat with seat belt holding it securely. You don't need a platform for an 6"/8" Dob but if you are observing on wet grass an old piece of plastic like a bin liner will keep the damp away.
    FWIW my previous car was a Peugeot 207 and my 8" Dob travelled happily with the tube in the boot and the base on the back seat.

  3. I'm aware there will be different views on this but for visual astronomy I would steer well away from a Newtonian on an equatorial mount. The first scope you link to was what I started with, would I start with this again - no!!! The scope itself is capable of giving good views of plenty of objects, I enjoyed the views but not the faffing about with the mount. Let me explain, an equatorial mount is designed so the mount points to the celestial pole, for us in the northern hemisphere that's the north pole. When an object is in view as it moves across the sky only the right ascension axes needs to be moved to keep the object in view. Sounds great - yes!!! The drawback is the optical tube rotates to get the object initially in view, the result is the eyepiece gets in positions where it is difficult/impossible to see through without rotating the tube in the rings. To me an equatorial mount is only needed for astro photography. As I say this is just my view, others may/will disagree.
    Good luck.

    Flamsteed P has caused me some confusion, I have assumed that it is the large, broken cirular crater outlined in the attached?  There was also a faint inner crater which I could see, concentric to the outer.

    I also took Flamstead P to be the large broken structure, the Virtual Moon Atlas appears to agree.

  5. Great info Stu.

    As you say completing the Lunar 100 is quite a challenge, needing to get the libration right to coincide with a clear might.

    I've been working on it for a goodly time and seem to be bogged down with a completed count of 85.5, the half is made up from only managing Armstrong from No. 90, haven't managed Aldrin and Collins yet but will keep trying.

    Good luck to all of you with this interesting challenge.
