  1. Very exciting indeed. Fingers crossed, and hope to se the usual great Mesu performance. Br. Heine
  2. Interesting read. I’m looking into putting a larger scope on my Mesu, so following this topic closely. Currently my Mesu is comfortly holding my 10” Quattro tight, but I plan to upgrade to a Hubble Optics HNA 16” or preferably 18”. The weight is 35 kg for the 16” and 45 kg for the 18” plus focuser and camera equipment, so could end around 50 kg fully loaded if aiming for the 18”. Your observation of possible flex with a load of 60 kg worries me, as I wouldn’t expect the mount to show visible flex. Could possible flex originate from the RA bearings? When you describe the movement/flex visible at the circular RA plate I assume you refer to the round black plate on top of the RA axis...the one where the mechanical lock can grab the RA axis?
  3. Thank for your advice. A Mesu is on the way. So excited to get everything setup and dialed in. LOL@Gnomus regarding the essential accessory. The training has begun. Maybe I can just workout dragging the mount and save the gym membership from now on :-) Essential preparations for going mobile with the Mesu Cheers, Heine Wieben
  4. Hi guys, Thanks for the new comments. If I upgrade it will be the Mesu. I feel this will be the safe choise. Having a piece of kit where you just feel glad every time using it will soothe the initial pain from the hit on the bank account. I'll probably manage to persuade myself during this autumn. Regarding the split option. I am considering this version, but at the same time I like the rigidity/simplicity of a one piece kit. Maybe the one piece version can make sense from a transport point of view. I've been thinking how to secure the gear in a safe way in the back of the car, and might have found a solution. I have a modified Mitsubishi Outlander with no back seats. The boot floor is basically extended all the way up to the front seats as one flat surface. This gives lots of available space. The height allows the 10" Newton OTA to stand upright. The idea is to build a kind of mounting frame consisting of a floor plate the width of the boot secured to the boot floor, and a smaller leveled top plate (leveled 10" or so) where the mount sits on top. The mount is then bolted on the top plate just as when it sits on a tripod or pier. Next to the leveled top plate a vertical rod mounted on the floor plate can clamp on the OTA dovetail and holds the OTA firmly upright. As you can see I'm still in the process of telling myself I absolutely need this mount . I'm sure I will succeed sooner or later. I have a friend living up north in the country who upgraded to the Mesu. When I go visit and see the mount in real life, I bet it will be like back when the wife persuaded to get a dog. Once you go and see the puppy, you know you will bring the beast home ?
  5. Thank you Olly, Steve, Pieter and Steve R, for your good advice. The Mesu really sounds like the wise pick. My current EQ6 carries my Newton OK, but I feel it is the mount is preventing me from improving the FWHM results any further. I'm convinced the Mesu will be the best to battle the wind and have a more smooth tracking. Not that the EQ6 haven't served me well, cause it has. Steve, scary with the mount moving around in the back of the car. I have been thinking what's the best way to secure it in the car. In an event with a hard brake on the motorway, I wouldn't like to have almost 30 kg metal loose in the boot. Steve and Pieter, thanks for the inputs for the tripod. I'll probably sell the EQ6 with the old tripod, so will find a sturdy one for the new mount. EQmod is not a must. I use Maxim, so as long as there is a driver for the Sitech it should be business as usual I guess. usually I just do one star alignment and plate solving to save time, so haven't moved to sky modeling etc. Guess I need to check the finances....the Mesu sure is tempting. Cheers, Heine
  6. Helle guys, Hope for some advice or thoughts on the dilemma Mesu200 vs. EQ8. I'm planning upgrading from an EQ6, mainly to get better tracking, and reduce the dependency of no or very light breezes. All imaging is done in the field using a 10" Newton. It will be a long while before I will get a stationary obs, so the load capacity is not the most important factor at this time. The weight of the mounts doesn't scare me. If I go for the Mesu I will still choose the the "one piece" version. The pros for the EQ8 is obviously the price, which is roughly half of the Mesu. Also EQMod is nice, and the handles might be a great help in the field. What worries me is if I can expect much significantly better tracking and wind resistance from the EQ8 compared to my current EQ6. Also backlash issues and tuning nightmares, is something I prefer to put behind. The Mesu is probably the safe, but also expensive choice. Besides from the cost the only thing which worries me is how cumbersome the Mesu is to use in the field. What tripod is recommended? I'm thinking Losmandy folding HD tripod. Any thoughts or comments appreciated. Clear skies, Heine
