    Anyone using an OGEM mount??

    After reflection and saw the deviation of the topic, the real question is whether this OGEM mount will be or will not be a good mount, suitable for astrophotography with good monitoring with a significant load possible. It is not necessary to compare it to any mount with gear or friction drive. It's my point of view.

    Can we compare high resolution motors with absolute encoders? I do not know and here I confess my ignorance. A small precision, the absolute encoders do not cost 800 € but 500 €

    As long as the OGEM will not be tried it would be completely stupid at the moment to compare them on their performances and their faults. The only comparison at present may be only on their resemblance and the price. Subsequently, it will be necessary to compare them side by side by doing the same tests to be objective.

    A question I ask myself: the Mesu 200 has stainless steel wheels as standard? On their website, this is not indicated.

    I do not agree with you: the Mesu 200 costs 4711 + 21% VAT = 5700 € without the counterweights The OGEM 3900 € + 600 € stainless steel wheels = 4500 € ((VAT included) and with 30KG counterweights ( and we know that the counterweights are not given !). Even if Mark adapts the controller SiTech, the OGEM will always cost less than the MESU 200 !!

    It's true that this is one of the few mistakes Mark made. To my knowledge, I have not seen a test report of the periodic error. I'm sure he thought he did not have so many problems with the FreeGo2 controller. Yet tests had been done with the Goto (see some videos). I think the problem comes from absolute encoders.

    This is the last new of Mark, JTW Astronomy (saturday 12): We are sending OGEM number 1, the first prototype to E-Eye remote observatory in Spain for testing purposes and to allow people to try before they buy. Our commitment to you is the highest priority. The Early Bird mounts will ship before we start to work on the next batch of orders. The reason that this mount has not gone to a customer is because it is a prototype and has some minor issues that are not present on the mounts you will receive. These are mostly cosmetic due to the repeated assembly/disassembly and fitting. It will function identically, so we feel it should be put to good use. Maybe you saw this already, maybe not, but we want to clarify the situation to avoid any misunderstandings. We've already started to received the first controller sets and everything is on schedule. Greetings Mark

    Mark may have made some mistakes (who does not?) But he dared to make a new mount at an affordable price. Let's be confident

    WAHOOO !!! , Japz, I totally agree with you, from the beginning to the end. You have all summarized. It is true that since the mount is in the hands of the FreeGo2 team, communication is rare. But what can Mark of JTW say, since he does not control this team? I'm sure he did not think he had all these problems! Clears skies (but for me, 2019 starts badly, not a single clear night since the beginning of the year )

    it comes down to putting grease on the car brake discs! The motor axis is in direct contact with the edge of the wheel and it is the pressure that drives the wheel. The surface of the edge wheel of the OGEM are treated against rust. There is no gear and worm in the OGEM mount training

    I understand the reaction of Japz, but he must understand that he is part of the early birds, and as such, he takes some risks. You can not have the butter and the cake. 2900 € for early birds, even adding the price of stainless steel discs, we come at the price of an EQ8, it's still worth it!! It is also true that sometimes Mark does not respond to emails; just send it back to get the answer....simply. Come on, Japz, more than a few weeks to wait, and after that will be only a bad memory .... and that happiness after! In the meantime, I will prepare for the New Year's Eve. See you next year and Happy New Year, good health and clear skies for 2019 Alain

    I have a friend who ordered an Unistellar eVscope as an early bird in October 2017. It should have been received in November, but it will not be delivered until early 2019 .... Any new project encounters delays. You have to be patient. When you buy as an early bird, you buy with full knowledge of the facts. Mark, since April, sent 18 "OGEM Update" et un "Final Update" to inform us. He kept us informed of the various problems he encountered, a rare thing, it must be pointed out and I find the words of Japz innacceptable. Is not patience one of the qualities of an astronomer?

    Anyone using an OGEM mount??

    Hello, I'm new to this forum and I'm French (sorry). I do not write English, put Google Translate will do it for me! I also ordered an OGEM mount knowingly and I wanted to intervene. A new product never arrives on the market as we would like.Mark of JTW Astronomy kept us informed with its "OGEM Update" and the last is dated December 28. Yes it has problems of delay but these problems are not due to the mount itself, it is dependent on the German team which deals with the design of the electronics (FreeGo2). Moreover,If the electronics was not finalized by the end of January, the mount's delivery date, Mark will offer the SiTech controller option. As for carbon steel discs, it must be said that it is carbon steel of high quality, says aviation. Some people already bury a product that is not out yet ... it's sad. And I have total confidence in Mark. Best regards Alain
