I own a NEQ6 mount and EQDirect cable, but the RJ45 version. The NEQ6 uses a DB9 port, so I got an adapter but I need to wire it myself. See attached picture of my adapter + EQDirect. I am quite unsure how to wire my adapter. The first diagram here should tell me how, but I'm still not sure I get it. If I look at the EQDirect adapter (see attached close-up), it looks like on pin 1 & 2, when the diagram says there should be ground there. Also someone in an INDI forum told me I could ignore the 12v pin as it would be supplied by the mount, but the RJ45 actually seems to have something on those pins.
It's tempting to just look at the wiring of both adapters and trust the colors, but I'm afraid making mistakes here might damage the mount...
EDIT: I own this RJ45 to DB9 adapter. Would any of the proposed wirings in this document work for my need?

I have a Skywatcher Newtonian telescope ( D:200, f:1000) The other day I noticed that the 'O' ring which was attached to the finder scope had broken. After a bit of digging around, I obtained what I believe is the correct size replacement ( 1.5 mm thickness, 52mm internal diameter). However, I can't see how it attaches to the finder scope ! Can anyone offer some guidance ? Many thanks in advance.
1. If the wire to a pair of 12v DC batteries in series is 10AWG (5.3mm2) and is say 2m in length, what gauge and length wire should join the two batteries, or as long as it is at least 10AWG and less than 2m it is unimportant? Are there issues with using thicker wire to join the two batteries together.
2. And if these two batteries were in parallel, what are the requirements of the wire joining these two batteries together? Again, is using thicker wire than the live and positive to the battery pair problematic?
3. And if you can tolerate answering another question, where would you fuse these two set ups?
There will probably be too much information below, but my level of knowledge in electronics is unfortunately low.
I own a EQ-5 - upgraded to pro with synscan, a SW 150pds and a SSAG guidecam on a 9x50. I bought this with the purpose of AP. I have my telescope on the porch, so i can sit inside with the PC (5m distance) and power everything from the socket in the wall inside.
I live in Norway where there is 230V 50hz AC in the wall.
I have understood most telescope equipment (?) is powered by 12v DC.
The mount came with a 12V "car-connector" which im sure people are familiar with. But i didnt wish to use this, so instead i bought a plug (European), which the picture below shows. It is like a multipurpose plug where i can choose 12V and also choose different "pc-style" connectors in the other end.
I am currently powering the mount via this plug to a 20m extension cord with 4 sockets. It's labeled "250V AC 50HZ". (picture below)
I plug the USB3-powered SSAG straight to the computer. I plug the synscan controller to the computer with an adaptor to make it USB in the other end.
So to the core of this post:
I now have an ZWO ASI1600MM PRO (DC 12V 3A), with a 8 slot ZWO filter-wheel (USB2.0 powered - guess this connects to the camera). On its way.
I also have a NEQ6 PRO on its way (12V 2A) - so no more EQ5 - but same power requirements.
And lastly i have a HitecAstro 4 channel dew controller on its way (12V DC) - which i plan to use with a Omegon secondary mirror heating strap, SMALL (https://www.astroshop.eu/heater-bands-controls/omegon-secondary-mirror-heating-strip-small/p,56529#tab_bar_1_select), and maybe something else down the line. The strap uses 0,18amps the product specifications says.
So....... With this setup, and from home like described:
-Plan is to use the 12v 2.25A adaptor-plug from the EQ5 on the NEQ6.
-Buy another one just like it, for the dew-controller. I dont know what Ampere it needs, but the dew-strap is only 0,18A.
-Buy a upgraded 12V 3A (or 5A) for the ZWO ASI1600 and 5m USB3.0 to PC.
-Plug filterwheel to ZWO.
-Plug guidecamera to PC as before - Or can this go straight to the ZWO?
-Plug the EQ6 via the Synscan ST4(?) to USB 5m to the PC.
So the mount, the ZWO and the dew-controller will go to the extension cord-cable drum outside which goes to the wall inside.
The PC will go to the wall inside ofcourse.
Can i do this?
2. If no: How should i do this?
