To my mind a novice could render their PC inoperable with the wrong registry setting (not likely but possible), so it's not something I'd ever suggest publicly without a ton of caveats. In my experience, whenever someone has needed to know what comm port a device is on, the suggestion has been to look in Device Manager / ports - which in itself isn't that intuitive (they don't have meaningful labels for a start). My post here is to say there's a quick and easy piece of software, particularly useful if you often plug and unplug devices, that tells you with a pop-up notification what comm port the device you just plugged in has been allocated... No ninja IT skills needed. 😉

I know what you are saying, but would you agree that those methods are pretty hard-core for most? For the casual user, there are plenty of install instructions that say "check device manager to see what com port has been added", and I just find it really useful for the computer to tell me the com port when I plug the device in, rather than digging around in the settings...

For me, it seems that every other time I plug in my flat panel it gets a different com port!

So, you plug in a USB device to your imaging PC and need to know what COM port it has been given so you can configure the software. Do you find yourself scrabbling for Device Manager and trying to work it out from the ports listed? I found this really neat utility on Sourceforge that does exactly what I want; I plug in a device and a notification pops up to tell me what COM Port has been added; Serial Port Notifier It is quite old (2016),but in my experience has worked a treat on Windows 10.

... and that's what I didn't understand 😉 Slewing is telling your mount to go to the exact co-ordinates provided by the framing wizard (i.e. where the box is located on your screen). However, because the accuracy of most of our mounts is not observatory-grade, the mechanical tolerances mean it will likely only be close. ish. Particularly on a long slew 😉 As your slewed location is therefore unlikely to be the exact co-ordinates the mount *thought* it had slewed to, Platesolving is used to take a picture and tell the mount the *actual* co-ordinates it is pointing to. A bit like a back seat driver 😂 NINA will then know the mount isn't pointing where it should be and instruct it to slew again, and as the mount will be quite close to the target co-ordinates, this second slew will hopefully be more accurate. NINA will repeat platesolving - telling the mount where it is actually pointing,until the results match the co-ordinates provided by the framing wizard. HTH Ady (I hope I've correctly understood your question - apologies if I've ended up teaching you to suck eggs..)

If you move the framing box, then press 'load image' to re-centre your view That is my experience - move the box then press 'slew' to or 'slew and centre' and it will use the new coordinates regardless of whether you have pressed 'load image' to refresh the screen. Not sure what you mean by this - the 'centre' in 'slew and centre' IS platesolving. HTH Ady

Talking about ports, I found a really simple program on source forge that will pop up a notification when you plug a USB device in in and say what com port it is on. It is quite old (2016),but in my experience has worked a treat in Windows 10. Serial Port Notifier No more scrabbling around in device manager trying to work it out 👍

The parfocal ring will slide over the nose of the coma corrector and will 'shorten' the amount of the CC that gets inserted into the draw tube. As long as this doesn't leave the CC too short/unstable to hang the rest of the imaging train on, you should be ok. The extension tube method lengthens the draw tube and so the length of the nose of the CC is unaffected. HTH Ady Edit: the click lock method also extends the draw tube, and as @bottletopburlysays, are an excellent addition if you have room in your imaging train - they self-centre and grip like **** 😉

I like this idea - very nice 🙂

@Sarek, Hi and welcome. As you have already learned, there are no shortage of options to suit any budget - and budget is the absolute limiting factor... Can you afford to spend big on a 'proper' mount? The EQ6 is better than the HEQ5 and the HEQ5 is better than the eq5. None of them are 'portable'*, but the better they are the heavier they are. You will want to spend money on other astro essentials, so I wouldn't recommend blowing the whole budget on the mount. Will you be imaging from the back garden, or do you need to travel to get a clear sky? I was finance-bound when I started and got all my kit second-hand and mainly from this week group: DSLR (eventually modded by cheap astrophotography), EQ5 (motorised, and eventually diy modded to goto), and 150pds. I've supplemented it with diy auto-focuser, dew control, imaging pc and filters, but these upgrades took quite a long time because of finances. The 'big upgrade' I decided to plump for when I did come into a bit of money was a dedicated cooled astrocamera (ASI533MC Pro). Still imaging on my eq5 and not regretting it 😉 So the tldr; is that recommendations need to reflect your budget and desire/ability to add funds... Ady Edit: *Oops - by 'not portable', I mean that you'd want to carry for any distance - they can all be unloaded from the back of a car and carried somewhere close...

Got this from the wife; I'm fairly sure she's after a new pair of shoes 😂

... or if I'm not paying attention 😉 Would you have such a thing running on rails, or some sort of castor arrangement.? I've no practical experience of this kind of scope cover, so I will sit at the back and watch. 😁

What do you have in mind as 'low profile run-off shed'? What size floor plan? Something high enough to stand in?

I have both and was about to say the Astro Essentials one is 32mm and so 128mm f/l, but I had a quick check on @FLO before posting and the description now says it is 30mm. Something is afoot, as the product code is listed as "ae_32mm_guide_scope" - hmmm... 🔎 There probably is that much difference between the two to worry about.

It is the guide scope focal length you need, which isn't anything to do with the camera. Mind you, if you have the ZWO mini guide scope, then by complete coincidence that has 120mm focal length. 😁 👍

It was designed to be used with the Star Adventurer, which aligns in a different axis. The actual setting will depend on how accurately you have leveled the tripod, for a start. Given that and the low accuracy of the scale itself, it is probably best just used a rough guide to start the PA process rather than expecting to be bang on.

Apart from polar alignment, you need to stick to one controller, or start again with alignment if you switch controllers (think of it like a reboot of Windows 😉)

You just need to choose your poison - skysafari is what I would use when planning a viewing session as I have my FOV overlaid on the star map to show what targets fit. Whatever you normally us should work, or even the FOV tools on astronomy.tools website will work to show the difference that sensor and pixel size have on your FOV.

The FOV is determined by your sensor size rather than distance to achieve focus (it is the same telescope with the same focal length after all). I went with a 533mc pro and the smaller sensor meant a smaller FOV than with my dslr. I plugged the sensor details into Sky Safari to see what FOV I would get whilst deliberating the purchase..

I think you are playing it down too much - it is a well-engineered solution that does *exactly* what you need, cossetting your precious Dob from any hazardous jolts as it is gently lowered to the launchpad with little effort from yourself. I think you should be very proud - I bet there's more than one envious observer reading this thread... Thanks for posting the vid, btw - I've watched it more than once

I recently managed to post a 48mb video of my automated RORO shed roof (zzzzzz) - how big is your file?

Looks great - I'd like to see the video.

I'm pleased with Affinity. I followed a few of James Ritson's Youtube videos and downloaded his macros (he's a product expert for Affinity Photo) and also use his macros. I don't expect it comes close to the power of PI, but it does for me.

There's always better kit 😉

Some inspiring pictures in there - I particularly liked some of the widefield ones (they feel more achievable 😉 ) Ady
