You are correct, but its a bit deeper than that. So its referring to the location of INDI server which then looks for local or remote device drivers. So you could potentially have the INDI server running on the RPi but the devices connected to another machine, in which case you would specify the location of the drivers in the Remote text box in Profile editor. @Ian McCallum if you hover over the the Local or Remote buttons you should see a popup with help.

Beautiful sights 👍

Absolutely agree. I remember trying to figure out how to read the SW polarscope as my manual shows the constellation view whereas the scope has a clockface

Here is my poorer cousin image of same object taken over 2 nights in Jan. Taken using the ASI224mc attached to the Celestron 130 scope on a EQ5 pro mount.

Great image. How many exposures is this? EDIT: Ignore Saw the info on the image

I have searched on the internet for examples of amp glow from ASI294 and all show just one spot from which amp glow is emanating. So worth checking that the rest are from camera or stray light.

Thats quite a few amp glow areas on the Master. Generally I have seen only one and its fuzzy not having starry lines. Perhaps someone with more experience of your camera can comment

If its anything like my Astro Essentials one you need to unscrew a lot before you achieve focus. 12cm is measured from the rear surface of the lens system in the front, so can be a bit tricky to figure out true distance.

From your description it sounds like the effect of air turbulence as mentioned by others. And as you view stars such as Sirius, these are quite low near the horizon at the moment, so turbulence will be higher. And if its skirting above nearby rooftops that doesnt help either as the rooftops are giving off heatwaves. If you could see faint rings in the view then its a case of poor focus. Good luck with your new found interest. Your local club should help a lot.

What is the spec of this? Presuming we are seeing the rear end of a guidescope?

Great looking images. Just a tad too reddish for my taste though 🙂 What tools are you using to post process the images?

A few features I like in Siril: (as we speak its with ref to v1.0.0-rc2) - Photometric calibration - Background gradient removal - Pixel math is new and has some great possibilities (havent tried in anger yet) - Easy to combine multiple nights sessions (even if they have different calibration frames) using Sirilic - Very active developers Features lacking: - masking - star removal - noise reduction (only median filter is available)

And in Siril you can get it to remove gradients on every image in the stack before stacking as well. This can help in certain cases.

You certainly can, but paid tools like PS have more functionality in that area.

It does have both Asinh and Histogram stretching tools. Asinh preserves colours better. But it does NOT allow you to do curve adjustments by individual channel

Any luck?

Then check the log tab and see if it there are any errors showing up.

What is the setting for CFA under Global properties? I have mine ticked to equalise CFA

Let me see the parameters i use. Simple check would be to take a look at script generated by sirilic and compare with OSC_Preprocessing_Withoutdark one. The sirilic script can be viewed under Actions menu. Suspect its something to do with registration as first image looks all over the place. EDIT: My parameters look similar to yours. I do use Darks but dont use Bias.

Its a lovely image I would be proud of. As @vlaiv mentioned there is a fair bit of signal + noise I have cropped the image and used Siril to do a photometric calibration. Here is the output.

Your choice of DSO vs planetary is also dictated by your scope. For planetary you need higher magnifications to get closeup views whereas for DSO you can get by with widefield. EDIT: saw that you use SW 120 refractor. You should get pretty good images of DSOs. If you use a computer to drive your mount then it would make your life easier. Take a look at the RPi as well. Thats a cheap option which delivers great results. I use a combination of laptop + Rpi and Ekos is a great software.

Thats a beautiful image. What is the duration of subs?

You could start simple by getting a pair of binoculars. Read this http://binocularsky.com/. Steve Tonkin, @BinocularSky the author is here in this forum so he might be able to assist you better.

Polemaster is great. But in my experience you can get quite precise PA with SharpCap or Ekos PA assistant as well and these are a lot less expensive 🙂

I'll second that 🙂 There is quite a lot to learn and @Andrew G you will need to get familiar with your scope, mount and software. Post processing is a whole new kettle of fish and that has a steep learning curve. I started my journey without guiding a little over a year ago (see link in my signature) and you can get very decent images with shorter exposures (you just need more of them). There is a term for it as well - lucky imaging. I have purchased a guidescope recently and learning to work with it. Good luck.
