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?
Baader optical wonder solution is practically Isopropyl alcohol. Instead of £12 for a 70mL of it, buy a 1000 mL of Isopropyl alcohol for £22 (before pandemic it was only £5). They have also smaller bottles which will be cheaper of course. The Baader solution and Isopropyl alcohol don’t remove the toughest of fungi on optics, only a few of the less deep set ones can be treated with them. I have used both for cleaning eyepieces and on certain stage of cleaning several 8 to 12 inch mirrors. They both worked identical. When applied through an optical cleaning fabric, they remove ( dissolve) fatty oils and fingerprints on optical surfaces. I had cleaned a 12 inch mirror once which for some unknown reason had ice cream stain on it (cleaning followed standard operation procedure for cleaning coated aluminised mirrors).
I am excited to join this big star gazing community! I realize I am abusing of your kindness, so that you in advance for any help you can give.
I have an old telescope, what appears to be a Meade ETX 90 from the early 2000s. I cleaned it pretty well after many Youtube videos and online research. I found full blown spider webs and dead spiders!
I have encountered a few of issues as I'm putting it back together and I wonder if anyone might be able to help.
1. I took off the screws of the back of my OTA (I know I shouldn't have!) and now I'm not sure how to put them back on (see attachments). When I try it seems to push the primary mirror instead of fastening to anything.
2. My secondary mirror flip is broken, the plastic piece part fell off. Is it possible to fix? The mirror itself is also very dirty (see attachments) and I don't think it can be cleaned further. Any tips on how to replace it and where to buy the parts? Or is it possible to not use the 90 eye piece viewport and instead use the front one so I don't need to fix the flip or the mirror?
4. My secondary baffle is sliding off. I've read that this is a problem w/older models. I tried pushing it to the right place and it requires some force, but after 1 minute it slides back to its original place. What should I do? Does this matter?
5. The plastic attachment to hold the smaller lens (finderscope?) wobbles no matter how tightly I screw it on. I don't know if it has anything to do with the front plastic part being a little broken.
Thank you for your help in advance, and I am still learning terminology so be easy on me
I am thinking of re-starting mirror grinding at home. I used to grind by hand and in this method, when we use the 1/3rd off-centre strokes for hogging out the sagitta, the upper glass becomes concave and would be polished into a mirror.
However, this time I'd like to build a Mirror-O-Matic or something similar and do not understand that if the tool is on top, how will the bottom glass become concave?
Or am I mistaken?
Is anyone on here signed up for the SkySafari and SynScan beta testing to natively support IOS? If so how has it been going?
