With the new mount Im seeing a lot less walking noise compared to the old one (Omegon Mount MiniTrack LX3 Essentials) and its a hole lot easier to get setup because of the easy polar alignment and goto.

Can anyone explain to me the horizontal stripe of noise at the top of the image? Its only red/yellowish noise and only there. Part of it might still be nebula, but especially to the left is a lot of noise. There are more stripes like this all over the image when bumping up the contrast and saturation. Some of them are more green and blue and some like this.

I took a few pictures of the most common objects and am using a Lumix G85 with a 100-300 (200-600mm eq.) lens. That is around 2.2lbs/1kg (Yes, that is a micro four thirds sensor) together with a Omegon Mount MiniTrack LX3 Essentials. It is a very cheap mount which you have to tention manually and it only runs for 1h at a time, polar alignment is hard due to the cheap "straw" you have to look through.

I really like this hobby and want to upgrade to a newer mount and the Sky-watcher Star Adventurer GTi looks really good for the price. However, I am worried about it's max payload of just 11lbs/5kg. For me it is more than enough, but I want to know if it will be enough along the way if I upgrade to heavier camera or even a dedicated one with a proper telescope.

Can someone tell me about the Sky-watcher with a heavier load or pro-level gear on a different mount and how heavy it is and if you think this mount will be enouh for it.

I like their services and have brought a few things, but their prices are 3-5x the price (sometimes more) of no-name chinese ones. I don't know where the parts of AZ-Delivery are produces, but its probably china too, but is this price right in your opinion. But even if they are more expensive than others on amazon for example, I don't want to support the evil bald man

How would or do you backup your home server? I don't have enough physical storage (for now) at home to store some backups, so I want to upload it to the cloud. Of course I want the backup to be encrypted, but I don't want to enter the password every time by server does a backup. I am currently using borg on my PC and do it manually. How do I create a encrypted backup without entering the key manually? Do I hardcode it somewhere? Don't really like that. I am also fine with trying other backup software.

My second (and first successful) try of the orion nebula. Any advice for editing out the noise and these stripes? What are these?

I want to upgrade my CPU in my HP ProDesk 600 G2 Mini as the current one is a little slow with 2 cores and 2 threads. I did a little bit of research and found, that my motherboard (HP KBC Version 05.39 (8169)) supports all 6th gen intels with 35 Watt TPD. Based on this, I found the i7-6700T and the i5-6500T.

This PC works for me as a home server with Minecraft at focus, maybe some Streaming service and a cloud later

I am completely new to the hardware side of PCs and don't really know if its even worth upgrading. I think the i7 is a little expensive for me, but I just want to know if both of these would fit my motherboard. Is there anything else I have to pay attention to when choosing a CPU or upgrading it?

I want to host a Vaultwarden (or Bitwarden if necessary) instance, but it keeps asking for a domain and a SSL certificate. I dont own a domain and dont want to enable port forwarding on my router to expose it to the outside.

Is it possible to host a instance only internally and access it via the IP or a domain set on my local DNS? How about SSL is it possible and/or necessary?

I have a (weird) question: Is it possible to connect a 3.5mm cable to a microphone‘s headphone out and the other end to a iPad‘s audio in, and record with it? I know an iPad is far from ideal, but there is no other options for me right now.

I recently discovered the Open Astro Tracker by OpenAstroTech. Does anyone have experience with it and can recommend it? I don't want to spend time and money for a product that maybe won't work, but I really like the idea of a self build tracker. I also like that it can be upgraded later by adding things like a autoguider

Because my camera is only ~1kg (2.2lbs) the small model is enough and I don't plan on upgrading anytime soon. If I can be sure it will work, its fine if it takes some time to print and assemble.

Also, can someone make a rough estimation of the price? On the website it is around 250€ for a complete kit, but I have a 3d printer and don't need the autoguider right now. For me that seems a little expensive for mostly 3d printed parts.
