Hi to all you members on SGL.
I am a novice with 3 months experience with a SW200P dob, having started initially with a pair of Oregon 15 x 70 Bins on a tripod mount.
I have referenced some good books and spent some time with Stellarium and I am encouraged by my new learnt ability to navigate the night sky with the 200p.
I have connected my Nikon D600 (24mp full frame) DSLR to the scope and produced some satisfying photos of the moon, however I am interested in imaging some DSO's. ( I have caught the bug with no cure in sight!)
I intend to get a tracking mount such as a SW HEQ5 Pro Synscan, but for now would like to purchase a wide field refractor and produce some wide field imaging with a basic mount, I understand that subs of around 30 sec can be produced with mediocre results initially until I get a better mount. Also it would be nice to have a grab and go scope which is more convenient than the big DOB.
Also this would give me some images to experiment with the software such as DSS and Registax 6.
So, I have been researching three achromatic telescopes, The Skywatcher ST80 and ST102 (both come with kit mounts ranging from AZ3 to EQ1 and the Bresser Messier AR-102/600 (which looks stylish and has the Hex focus)
However, despite spending somewhere in the region of 4-5 hours so far researching for reviews on the BM102, nothing has been forthcoming>?
I am aware of the issues of CA with these small tube Achromats, however the plan is to Purchase one of the three now, save for the HEQ5 mount, then at a later stage use the scope purchased now as a guide scope and but a better APO doublet or triplet scope for the main tube.
So, having laid the table so to speak, which of the three would you advice and why please, I have been told by two companies stocking the BM102/600 that mechanically it is far superior to the two Skywatchers, but I am concerned that I cannot find ANY reviews on this OTA for its optical quality ?. I am aware that Synta make a few of these 80 and 100mm scopes for different suppliers but I am let to believe that the BM is a separate manufacturer.
Any advice or better still hearing from someone who owns the Bresser Messier AR-102/600 would be amazing, so thank you for reading this long post and thank you in advance of your reply.
I have a VERY heavy duty pan tilt Manfrotto tripod which I previously used to support my Sinar 5x4 Large format bellows camera so its very steady and has a pan tilt head already fitted, I intend to mount the new scope on this as an AZ to begin with.

This has been sat boxed up in my garage for a couple of years now since moving to a town with lots of trees and light pollution! It's in great condition optically and physically other than a scratch on the outer paintwork that it's had since I got it (see the bottom picture). Comes complete with tube rings as seen on the pictures. Buyer can collect or I can meet at the Kelling Star Party with it as I'm only a few miles down the road. Reduced to £160.
I've recently bought a Skywather 102/1000 refracting telescope mounted on an EQ3 with aluminum tripod.
The optics are okay, but I'm very disappointed by the low quality of the mount. Here's why.
1)First of all, it is too wobbly for my taste.
2)Then, the latitude markings are off by about 10 degrees from the vertical/horizontal. This is not a functional problem, rather an eye sore. Can it be fixed? I guess not. The black plates seem to have been glued into place.
3)There are two marks on the mount for setting the declination circle but they are not on the same diagonal, meaning they don't show the same declination. One of them is on the declination knob assembly, which is slightly rotated so as to not hit the telescope. Does this second indicator have any meaning? I don't think so.
4)Hard as I tried, I was unable to attach the round cover to the polar scope (the part where you are supposed to stick it in). Do you need a polar scope to be able to attach it?
5)The manual is very light, it should really more information on the mount. For instance, what's the use of the piece I've marked by a red circle?

I have just spent a week in Swanage.There were several very good dark and clear night skies before the Moon rose earlier.I took full advantage by testing my new 200mm Newtonian. I am coming back to Swanage later this month and have decided to leave the setup down here.This gives me to opportunity to concentrate on building a travel or grab and go setup. I have an older blue colour Skywatcher ED 80mm f 7.5 telescope. I have used it with a large Manfrotto photographic tripod.But this has limitations as the telescope cannot be pointed to the zenith. An AZ 4 mount would work well I know.But it is quite large to transport.I have be looking at the Skywatcher AZ Discovery setup.The tripod does not look to be anything near the 1.75 inch diameter of the EQ5 tripod. Also there is the new AZ5 Delux mount with height extension.Just wonder if I could buy the mount and extension and fit it to may Manfrotto tripod.Has anyone else had any experience of such mounts? Even goto would be considered if portable enough.
Im currently using a Sky Watcher Star Discovery 150P, Ive had it for around 7 months now using only the eyepieces that came with it which are a 10mm, 25mm and 1.25" 2x barlow. Ive had some great nights with these viewing the Moon and various stars but now im looking to expand what eyepieces I have in order to get more out of my viewing experiences.
Basically im looking for recommendations as im still very much a beginner, any help will be most appreciated.
