I used the add on "Flash Player 2022" in Edge and the Alignment Simulator is functioning 100%.

I am wondering how you achieved that result, maybe you could explain how you managed to get this extra detail.  

I use Affinity Photo. It is 50 euro for a very capable software. I just stretched your photo once with LEVELS and once with CURVES. Search youtube for Affinity astro tutorials and you will find a lot of good advices.

You have a lot of information to still stretch from your picture. Did a quick and dirty mod of your jpg file (which is not recommended really) and there is a lot to reveal...

I just wish I could improve on all my ZWO cable management. 🤔

You know there are separate USB2-contacts for shortening long cables? Just cut to correct lenghth and solder. This is ad from our local electronics supplier in Sweden but they should be available worldwide:

Talking about reducers, the Starizona 0.65 seems to be in stock finally. Can be ordered with threaded adapter for Esprit 100. Anyone here tried it?

Without internet, you cannot access computers or mobile devices. You need to have internet access for the same.

From Teamviewer support:

"When connecting to another device within your LAN you can enter the IP address of the remote device into the Partner ID field on your TeamViewer client in order to connect via LAN. Click on Connect to partner, and enter the remote computer’s TeamViewer password when prompted. Now you are connected to the remote computer directly over the LAN, without using the internet."

Anyway I left it running for 10-15mins. Temp down to 3.5 degrees. So pretty good I think. 

And what was the temp difference when you pushed vs pulled air over heatsink? You asked the question and you can tell us!

@Juicy6 Out of interest what is the thing ringed in red below?

One reason I now always take a picture of the final setup is that often determining this back focus is not straight forward...

Steve

Me too. I use same camera on two scopes. So easy to forget the thin spacers.

"... happens because surface of best focus is not flat like imaging sensor but rather curved like this:

Either your center is in focus (more often) and sides are out of focus, or center is out of focus and edges are in focus - but they can't be in focus both at the same time."

We will have to wait for this: https://petapixel.com/2017/07/21/nikon-patents-35mm-f2-lens-full-frame-camera-curved-sensor/

If I use a filter cell adapter before the flattener which is 9mm wide apparently (I couldn't see any other way of using a 2" filter) will this affect the back focus? My imaging train would be camera with 11mm adapter, 16.5mm and 21mm adapters, M48 adapter, flattener. filter cell adapter.

Peter

No, distance from flattener to sensor remains the same. But you will have to move focuser draw tube inwards 9 mm. Or you can use a filter drawer...

My setup, 57,3 mm + 6,5 mm = 63,8 mm, minus one third of filter thickness gives close to 63 mm.  The spacer/extender ring to the left of the flattener is 8 mm so distance from this ring to sensor will be 55 mm.

So 16v output from PSU and I have 11.9 at the mount!

Not a good plan. You will have correct voltage at full amperage but way too many volts when only low consumption is drawn. You need to use thicker cables!

15 m cables - you need to look at this:

IThe RPi4 doesn't boot off USB3 yet but there is quite a simple mod that's available that allows the system to run completely off the SSD.

10AWG will result in a minimal voltage drop. For 2 meters and estimated consumption of 5 Ampere you will see only 0.07 volts drop. Use same wire between batteries. A 10-15 Ampere fuse near batteries will suffice for protecting cables.

Wow, amazing project. I like the video presentation. Very exciting!

Christer, Sweden

Nice project. I use a similar tool box for my batteries. Add a luggage strap for security! The plastic lock is not to be trusted beyond zero.

And what limitations are there. The videos show that it requires a guide scope (would it work as an OAG?)

FAQ says it is working best with guide scope 100-150 mm FL. OAG is not recommended (possibly because FL will be too long).

The possibility to polar align after plate solving and analysis of ANY part of the sky is something I have waited for. But I rather wait for this function in Sharpcap or similar software than paying 1000 euro.

You think its for that brand in particular, and maybe other brands could deliver better or? 60mb/s will work for me now, but just wandering for the future sollutions i could bump into

I think this is about the same for all brands. Maybe the repeater amplifiers are set to this speed to ensure no data loss. But, again, 60 MB/s is far beyond what is needed with today's cameras. Lucky imaging/planetary work with an ASI6200 and 62 Mpixels images might pose concerns, haha...
