You're so welcome!

Sorry this video wasn't helpful for you, I will try harder next time.

Good luck... This is a scientific instrument. Wrong hobby.

Thanks for your feedback, It will help in making future videos.

Thanks for your feedback, I will try this month to make a follow-up video.

It’s impossible to have them all tightened up. The secondary mirror will not be aligned. The whole point of the three screw method is to tighten and loosen to get the mirror perfectly perpendicular to the axis.

The secondary mirror is held in place and balanced to the frame with a small rubber "O" ring. The 3 collimation screws are used to either compress OR relax the pressure on the "O" ring until the secondary mirror is aligned with the primary mirror.

Glad it was helpful!

Thanks for the tips! So True!

So very true, I thouroghly enjoy the experience, but it is a completely different lifestyle.

Thank you! Will do!

Last night in the Olympic mountains I had to get up twice, but I got 6 hours of sleep still. I have a heated pad on my bed that makes hoping back into bed fun.

Thanks for the feedback. I appreciate it.

I used the top of a liquor box for the template and used a razor knife to cut the cardboard. This is a custom cutout so I don't think it is for sale anywhere.

The dots of different color represent the different "Triads" of the scope itself. When you move the template around in a circle, you will see some spikes which are not evenly separated, and the collimation screw which is exposed will be the one to loosen or tighten to evenly space the spikes.

This would be a great "Off Season" hiding spot for the weekend.

Thanks much, comments motivate me to produce more videos.

A Tri-Bahtinov mask has 3 sections. The cardboad mask isolates 2 of the 3 sections to assist in deteerming which of the 3 collimation screws will be adjusted. you can display the section where the spikes are not even and adjust the associated screw to widen or narrow the collimation spikes for that section.

@@Zealor365But adjusting one screw for one set of spikes simply impacts the others so you end up chasing your tail.

@@Zealor365 No cardboard is need, just place your hand next to one of the collimation screws to see if the shadow of your hand corresponds to the set of spikes you want to adjust.

Thanks for the correction.

Plugging it in directly to the source provides full power continuosly. The amp draw is stated in the product description of the vendors website, and is dependent on the length of the strap.

To be honest, I am giving up on the SCT and going back to refractors.

Last night I spent between 1.5 and 2 frustrating hours trying to collimate my C6. I used Arcturus, which was up around 60 degrees, as my target star and began trying to use a Tri-Bahtinov mask. I couldn’t make any headway and might have made things worse, so I shifted to the airy disk method. After the airy disk looked like it was about one step away from good collimation, all of my effort made things much worse, and whatever I did with the collimation screws, I couldn’t get the circle we want in the center to move away from the edge. Disheartened, I gave up, decompressed for 30 minutes, and went to bed. I in my fourth week of recovering from Covid-stopped testing positive four days ago-so maybe the virus is affecting my judgment, but at least last night I was thinking of getting out of the SCT business and working primarily with my William Optics Redcat 61 on my AM5 mount and controlled with an ASIAIR+, which works great. And this after buying a used Celestron 8se just a couple of weeks ago. Haven’t looked into its collimation yet, and after last night’s debacle, I’d probably be afraid to try to adjust it if need. Not sure what to do, but the thought of leaving SCTs behind has some positive aspects. So it’s interesting to see that’s exactly what you are doing. I’m a member of my local astronomy club, so maybe I can pay someone much better at collimation than I am to try to get my scope(s) collimated.

I bought it from Oceanside telescope. They went out of business 6 months ago

Thanks,

My friends don't like to be in videos.

No, but it can be switched in about 15 minutes. 4 screws

HEM - Harmonic equatorial mounts do not require balancing on the RA axis. I do balance the DEC axis per the instruction in the Iopton manual for the HEM44.

Everyone is talking about the ZWO AM5 and I think I like it.

It's cloudy this week. I might get some imaging this weekend and will tape the activity.

Here's another video of my review of the EC version from The Astro Imaging Channel.

Thanks!! How are You?

The setup shown is for display purposes only. The telescope is used on a EQ mount in practice.

Thank you.

Thanks so much. I appreciate the feedback.

Thanks for the suggestion. I'll give it a try.

Good tip, I will change the password for the 5G side. Thanks,

I remove the dew heater at the end of each nightly session.
