Taurus T400 Ultra Light. Overview and assembly.

[@shalabazertheboltstruck8645]

What a Beauty! What a Machine! Thank you for this one sir 👌

[@pierrevesper4348]

Good morning, Allow me a small correction: the screw holes on the primary mirror box (where the altitude axes attach) are not for varying the focal length (that would be impossible anyway, as the length of the tubes would not vary ;) ). They are here to move the primary mirror box forward or backward, and thus to adjust the center of gravity of the telescope. It's for balancing. I also own a Taurus telescope and I'm fully satisfied with it! :)

[@nomisastro2000]

Thank you for enlightening me on that. I was just theorising as I didn't really know.

[@jensketelaer5711]

I orderd it some month ago and I‘m really nervous. Nice vid, thx a lot

[@nomisastro2000]

It was a 6 month wait for me. Hopefully you have no issues and fall in love with it like I have. What extras did you go with and standard or pro mirrors?

[@tedbracht4504]

Hi Nomis, Based on your review (and some others) I now have a T350 on order and am wondering whether I should add the main mirror cooling fans. What is your experience regarding cooling times? Thanks

[@nomisastro2000]

Nice to hear! I do not think you will be disappointed. I personally do not think the cooling fans are important. The entire back of the mirror and cell is exposed and I find my mirror has cooled down plenty with in 30 minutes of setup to give excellent views at the eyepiece. Keeping in mind that I keep my scope in its bags in my garage, whoch is only a few degrees warmer than outside. What I consider essential is the heated secondary but most of all the storage bags, those are must have. The DSC is outstanding too and am so glad I ordered mine with it. The simplicity and excellent accuracy of it has not made me miss GOTO at all.

[@tedbracht4504]

@@nomisastro2000 Thank you so much. Yes I did add the secondary heater, the bags and the dsc. I will be storing mine in ambient temp as well (a garden shed), bit concerned when the sun shines it gets too hot in there (flat roof) so in summer I think I'll be storing it inside but in winter it will probably be same temp as outside. You had some bother with your mirror but that got all sorted didn't it?

[@nomisastro2000]

@@tedbracht4504 Yes, my mirror had water stains. The mirror went back under warranty but was then covered in dust from the packaging upon return, so I ended up washing the mirror to get it to my standards. Hopefully that is something Taurus have been keeping an eye on but they really do need a better way of shipping mirrors on their own as it was rather awful. Should you have any issues I found them great to deal with but most do not get my bad luck, ha....

Hallo Nomis, bald kommt mein Taurus 353 Dobson. Dein Aufbau-Video hat mir schon mal einen guten Einblick gegeben. Was mir nicht ganz klar ist, wann und wie die Schutzhülle montiert wird. Toll wäre auch ein Video über die Benutzung des DSC-Systems systems. Hast du so etwas schon gemacht? Dein Video war das einzig wirklich gute Video über Taurus dobson, welche ich in KZbin gefunden habe. Für alle anderen, die vor der Anschaffung stehen, noch einen Hinweis: ich habe mir von Taurus die englische Bedienungsanleitung digital schicken lassen und die durch ein Maschinen Übersetzungsprogramm laufen lassen. Das hat wirklich super geklappt, das meiste war recht gut übersetzt. Zusammen mit Deinem Aufbau-Video bin ich jetzt bestens gewappnet. Vielen dank, und weiterhin viel Freude mit deinem Dobson

Hallo Johannes, Danke für Dein Comment. Es freut mich zu hören das Du ein Taurus 350 bestellt hast. Es ist ein tollen Große für ein Teleskop und Du werdest nicht entäuscht sein von der Qualität. Ich hoffe das es eine aufregende und bereicherende Erfahrung wird für Dich. Es freut mich das mein Video hilfreich war. Bezuglich die Schutzhülle die Du erwähnst: wenn Du den schwarzen Dekke meinst die den Traversenstangen auf den Teleskop bedeckt, dies wird über die Traversenstangen geschoben bevor den zweiten Spiegelumbau angebracht wird. Es ist mir oft passiert das mein rotes Licht in das Okular reflektierte. Es funktioniert auch um Tau auf die Spiegel zu verringern, aber dazu wirkt auch die Heizer des zweiten Spiegels sehr gut. Ich wollte ein Video über das DSC-System machen, aber der eigentlichen Installation und Software setup war so leicht das ich es nicht für nötig hielt einen Video zu machen. Aber ich könnte einen Video für Dich machen wenn Du meinst das es Dir hilft? Was ich Dich rate ist das Du SkySafari Plus oder Pro käufst für dein Handy oder Tablet und das verbinded mit dem DSC mit WiFi. Es ist mir noch nicht gelungen das es funktioniert mit Bluetooth, aber es wirkt gut mit WiFi.

[@johannesschonwetter8111]

Vielen Dank Nomis, ja jetzt, ist es mir klar mit der Abdeckung. Ich werde das mit der Software probieren, sobald mein Teleskop da ist. Ich berichte dann mal kurz darüber wie es läuft. Wünsche dir ein frühlingshaftes Wochenende und vielen Dank, Johannes

Enjoyed your video of the T400, looks like a nice dobsonian. Can I ask does it suffer badly from dew ?

[@nomisastro2000]

Thank you. So long as you use the shroud the primary never dews over and the shroud hanlde the moisutre very well. I got the heated secondary but as I used the shroud all the time I have only ever saw it come on once for about 10 seconds.

[@moorekatt]

@@nomisastro2000 That's great, thanks for that.

[@Miguel_Noppe]

That's a nice telescope 👌🏻

[@davel4724]

wow, this looks great !!

[@nomisastro2000]

Thanks Dave, You're more than welcome to give it a try next time we cross paths. Its even more beautiful to use as it is to look at and the views are outstanding. I got to see G1 in M31 with it just a few weeks ago and was able to share the view with a few of the lads from the club.

[@relaxerization]

Such a small secondary mirror. What is the focal length?

[@nomisastro2000]

It's actually quite big. I think there is a bit of an optical illusion going on. The sipder and secondary holder are so thin and small - but of very high quality - thus making the secodary look smaller than it is. The FL is 1800mm, which is spot of for an F4.5 16" mirror.

[@relaxerization]

@@nomisastro2000 Have you been able to see the Andromeda galaxy's spirals by this scope ?

[@nomisastro2000]

@@relaxerization Yes, with good seeing and trans, easily from my Bortle 4 site at home and I have also seen G1 and the star cluster NGC 206 very well indeed.

Nice telescope. ..bad audio clip
