I left it alone for 10 days

You also mark and drill indentations in the steel washer to match the screw positions, that helps prevent the washer moving in relation to the secondary mount. I used a couple of layers of HDPE between washer and secondary.

While you have the secondary mirror of, install a steel washer between the spider and the mirror. It will stop the screws catching on any indents on the mirror caused earlier, and makes mirror rotation smoother especially.

The issue with the Moonlite CR2 is that they are no longer manufactured as per MoonLite Model CR Newtonian Focusers

I am looking for recommendations to replace the stock Skywatcher focuser on the 10” Quattro. The steel track seems to be a good replacement, but obviously feedback from members is going to help me focus.

Well come. here you will find many insights - including opposing ones All worth considering tho’

After my last post, I have fallen out of the shower and injured my back, so, no bending until this week. also have had an eye checkup, but need to go back for another review next week and will hopefully get that signed off. So, next steps will be fit cameras confirming dome and shutter functionality laying floor lining and flooring set up power Set up rig start imaging as if it would be that simple. for example I really do need to decide whether this set up will primarily be imaging emission nebula or galaxies

I have. As there is no set point for temp, you can’t get it to a specific temp in different ambient temperatures. It did bring the temperature down and I got images with quite a bit less noise.

That’s what I was saying.

I’ve been looking at insurance, and that is one thought that I had. May be over much overheard for a retail company tho’. Despite their remarkable service, they are only human (I hope).

As I have recently seen completion of an observatory installation, I will be reviewing this over the next few weeks. I would appreciate any feedback on subsequent posts. The first will be a simple list of stages to consider.

Many years as a PM, I got used to writing them. The version posted was passed for approval, I just didn’t post the approval.

From http://astronomy.tools/calculators/field_of_view, here is a potential view of Jupiter using 250P, 2x Barlow and a Celestron 20mm Plossl eye piece, and showing the overall FoV

There is a web page that will let you get an idea of different targets with a wide range of OTAs and lenses. http://astronomy.tools/calculators/field_of_view/ You can then get an idea of the differences.

Thanks It’s great being able to see with both eyes again.

wet weather after a week to let everything settle, the cataract surgery last Wednesday. I can now see!!!! another few weeks before I am allowed to bend and lift heavy kit, then full steam ahead, I hope

As I understand it: The AM5 and AM3 mounts are effectively German Equatorial mounts in that they follow the “t” shape design. See https://en.wikipedia.org/wiki/Equatorial_mount These newer ASI mounts, and others, implement a different drive mechanism which is said to be backlash free and allows for higher torque in a smaller body. See https://en.wikipedia.org/wiki/Strain_wave_gearing

Perhaps to protect you head from repeatedly striking a brick wall when the mist comes in after 25% of your session has completed?

I had a pier and mount outdoors for, oh, best part of two years ( I lost interest) with no signs of rust, corrosion etc. It was under and telegizmos cover. There is another rig I keep outside often which all the control technology, again under a telegizmos cover. Not has any issues bar some spider webs - which one would expect if left a few days.

There is a whole load of threads under DIY observatories - worth a review.

If you choose the ASI Air/Pro/Plus, only ASI cameras are supported; mono or colour. Support for a focus motor or filter wheel is also limited to their products currently. The list of of supported mounts in quite extensive - see their website. I have to say that I have not has any issues (other than my idiocy) with setting up and running. Should have also mentioned that polar alignment is also available with that ASI Air models, as is image scheduling, plate solving. For my rigs that have other manufacturer’s filter wheel, cameras, etc. I use a windows stick running SGPro - all devices I use have ASCOM drivers.
