I'm really pissed off the way a lot of them like the one I got Antares doesn't even come aligned! Having to collimate a collimator is ridiculous and the last thing I expected at my school!

What if the central circle on the concenter tool is below the secondary mirror ? What does this mean?

Is that dew shield custom made? It looks so neat.

🥳

Great to see you back 👍🏼

Nice work Daniel. Have you seen the system Astrobloke in the UK installed? I'm so impressed watching you guys build automated roll off roof observatories. One day I'll have one too. clear skies

Never use a lazer useless use a cheshire with cross hairs short for fast and long for anything over 5.5f

great video, ship the music next time

Have you thought of using a high sensitivity accelerometer. They are designed to detect ultra low levels vibrations. Just my two cents.

10M has a similar method of balancing, but if I do the routine then power down and put DEC vertical the scope is not balanced. This ever happen to you?

I been messing about with collimation for 2 years everytime I moved it it was out so I decided to take primary mirror to clean and found all three mirror clips lose so tightened them all

Hello Daniel again... I have a other question: Is this mirror made in Germany? Or is it only tested in Germany? Does the certificate indicate where it was manufactured? Thanks

Why don't you just do the job that your music is doing and tell us to f@ck off ?

It would be nice to have a winner gifted your handcrafted optical rig :)

Can you post a link to the ASA paper?

Excellent video and explanation! Thank you for sharing your simple yet effective rig.

Their are hardly any videos of this company on youtube. Most videos are a good 12 years old. Is this company still alive?

Absolutely fascinating .

Hi. Do you publish your astro pictures somewhere? After watching several of your videos I can sat that your whole setup is so great and perfectly setup. Absolutely no corners cut.

what are the costs of that thing? If that's 50k forget it lol.

4 year old video are you still using the focuser and if so happy

Hello Daniel... I have seen in a video that you put a smartphone with a support attached to the concenter. Work better? Thanks

Hello Daniel and thank you for your informative videos. Could you tell us if there is an improvement with the new secondary mirror? or maybe not. Thanks

Where to get that Pegasus Astro Power Box? I need this, can't find the device! I've been looking for something that calculates dew point & then controls heat strips. My use is for a camera enclosure that has a glass window. tyvm! I must say though, I've never seen anyone use an RCA jack for power, that seems crazy.

Name Focuser motor?

Hi congratulations, I saw that you use sharp cap software for video captures. I would like to know if you can make live flats with sharp cap software on the solar disk.

Thank you very much, this technique was great to follow, cleaned my mirrors and the look 99% better than before. I still have some specks but I have to live with that. Unless you have more ideas for the stubborn ones. Maybe more dish detergent focus on those specks? You think that will work? I wish I can show you pictures here.

what kind of wipes should I look for? I am worried about getting some that rip apart when wet.

Congratulations for this excellent video!! 👋👋👋👋 I am thinking about it for my observatory

The autocollimator alone will still allow slight axial misscollimation to remain. Try using a laser collimator on your scope after collimation with the autocollimator. If the laser does not point to the center of the primary, rotate the secondary to 1/2 the angular axial error amount and then recenter the spot with the secondary tip/tilt screws and then primary tip/tilt. Follow up with the autocollimator, and you should be very close to true collimation. Verify by using the laser collimator again. After the laser collimator and autocollimator agree, further use of the scope only requires tip/tilt adjustment of the secondary and primary.

Often overlooked is misscollimation due to slight axial rotation of the secondary mirror. The three tip/tilt screws won't fix this. If your laser collimation tool and autocollimator do not agree, this may be the problem.

Yes, well. if only ASA would still make the mount ...

Hi, Nice video.Where can you buy that thin anti-condensation band?

awesome tutorial Daniel, I am heading to New Mexico tomorrow to reinstall my OOUK AG16 and i can tell you it is very dirty.

I'm confused. You didn't show how to use the program.

In the UK, Altair Astros 26C is waaaaaay cheaper than both these efforts by over £600/700 so its a no brainer the imx 571 26C.

Thank you, I believe I'll give this cleaning technique a shot tomorrow.

I had forgotten about fans, thanks! Connecting the heater directly to the battery could also damage your telescope if it gets more than warm. Without a heater controller you lose some level of overcurrent protection for both the heater and the battery attached to it.

Is the primary mirror base custom made? Do you have a design for reference?

When different manufacturers make their implementation of the same chip, the implementation should be evaluated. Technical data concerning the sensor is the same for all of them and only differs at the behest of the corresponding marketing department. ZWO clearly follows a plug-and-play strategy, whereas QHY demands more expertise from the user. In return, QHY also offers more options.

hmm, I recently learned that weights should not be hanging out that far from the axis of rotation, or it can cause ringing. Any thoughts on that?

Thanks for sharing! Ewww .... looks like a lot of sticky pollen. Birch and pine maybe? Have you considered replacing the mirror retention clips with an aperture mask doubling as a mirror retention mechanism to get rid of some of the diffraction in the system? Interesting program to simulate the effects of shapes of seconday obstructions and mirror clip configurations is Maskulator. You can make your own masksof course. The program can be found via cloudynights.

🥳

Wouldnt buy ZWO. Altair Astro/QHY or Risingcam made by Touptech have no issues with either vibrating fans or thermal paste bleed.

This seems pointless to me, there's just as much chance that the tilt in your system comes from the OTA and not the camera sensor.

Wow! Forget the camera! Is that a mower?

Which version of glatter laser do you have ? 635nm?

That carbon scope looks sooooo good. I'm going to paint the secondary on my dobsonian after watching this!

Daniel, do you have a link to that cable you mention in the video?

i was hoping this would show me how to use the howie glatter laser collimator with celestron 8 sct. i am lost!
