The link you gave goes to your Imaging the ISS with your 16

I apologise to any that were misled that was infact my imaging the ISS video with the 16", i tried to stagger the video releases but put todays date on the teardown instead of the 4th and cut and pasted the wrong link while uploading.

 

Here is the one man teardown https://youtu.be/bLCgt94-4sM of the 24"

 

Sorry again

Damien

Nice video, that didn't look too bad at all. It's especially impressive considering that it would be even faster if you had a mirror box or other mirror solution you didn't have to mess with that much. Now I'm wondering how well the collimation holds up when you get it put back together.

Thank you mate,

I am surprised how well the scope stays around the collimation sweet spot. It is better than my 16" for that, it is build slightly different so not sure of the reasons but i have deffinately noted it. After the 2nd night i left the scope out unused for about 17 hours and i filmed a little clip of me uncovering the scope getting ready for the night and putting the laser back on it all in one take and it was still spot on. And the collimation adjustments are on the miroor side of the box which makes it easier to collimate again over the 16 inch.

Gday mate and thank you.

 

I haven't weighed it but my "guess" would be 50+- kg {110lb}, the whole scope weight 70 - 80 kg

2 people would be no problem as long as you have a big enough opening to go out, if I remember correctly it was 88cm across at the rocker box.

Strangely enough, you install the mirror box+alt bearings into the rocker quite easily (in the YouTube video). How much weight of your alt bearings?
I made the weight of my carbon 24" mirror box+Kennedy mirror (47 mm edge thickness, weight 25 kg)+carbon alt bearings, total 40 kg. I install it in the rocker with a belt on my right hand.

Which video are we talking about?

 

I think what you saw was me puting the scope together without the mirror installed.

 

The weight of the "box AND mirror" is aproximately 50kg+-, I have never built the scope with the mirror in the mirror box.

 

As stated before the mirror is listed as 30kg and the mirror cell and ALT bearings are possibly up to 20kg (i have not weighed it) in my opinion. With each altitude bearing possibly weighing 4kg each.

 

Hope this helps

Damien

1:18 minute. There is a mirror box + mirror + alt bearings assembly. 50 kg?

 

Ps. My carbon version 24" f/3.3 https://www.cloudyni...ope/?p=12424159

40 kg similar part.

Hello all,

 

Here is a 1 man teardown of the 24" if anyone is interested.

All the best

I took the link from here.
I looked further on another topic page. I don't like manipulating a heavy mirror at night. It is necessary to invent something or forget about one man.

Look at my post immediately after… then look at post #76 where he describes what happened.

I 100% agree with you on this topic and building it before use is not ideal or easy like with the 16" Dob which takes 15 minutes, I am going to build an area where I can leave the scope set up instead of building and pulling it down regularly. I have contacted some people to build it although they are busy and I may end up building it myself.

When it comes to shipping do they send any tracking info or indication that it has left? Or is it when they ask for final payment that it is sent? I am still early in the 10 week shipping window that they quote on the website, I did not know if it is just going to show up one day or if there will be an email saying expect it on X day.

Gday Jared,

I'm my experiance (twice now) there will be and email sent to you and it will have shipping tracking numbers for each box (3 boxes for the 16" and it was 4 boxes for the 24"). This is usually sent a day or 2 after the telescope is picked up. From the look in your Bio i am guessing this will be your biggest scope now and you will be super excited to get it. They are in the middle of their chinese new year celebrations so you may find a small delay with that.

 

All the best

Damien
