I am almost a noob to telescopes, but in the past weeks I have been watching Mars, Neptune, Saturn etc. But absolutely no look with any galaxy or cluster.
And guess what, I LOVE IT!
I own a Celeston Nexstar 4SE and a Nikon 3100 but I have no idea what I need to buy to connect them. Something like a T adaptor or I dont know... please help!
Also, I would love to use some filters and a wifi for my AUX so I can use the app on my phone. So it woul be great to help with those aswell. I know that my telescope is not very good with nebulas and stuff like that, but I guess it can still take some decent shots of them right?
Last night when we was out in the night to do astro photographing I got problem with my Star Adventurer mount. The friction coupling in RA axis got stuck and I have difficulties to aim the camera to the object.
Today I have dismantled the mount to find what the problem is with it. I got to repair it, I took photos from my disassembling and repair that I think can be interesting for others to look at and read.
Here is the link to my homepage:
Have any other of you had a simular problem with the Star Adventurer mount?

Any idea where I can find an M54 female to M60 male ring adapter? I need to order it online since there arent any astroshops where I live so I'd really appreciate if someone can link me to such an adapter.
Basically I have a TS Optics 2" Adapter with compression Ring for Skywatcher Newtonians, TSM54-2 and I need to use it for my celestron newtonian which has a 60mm drawtube so I'll need some sort of adapter.

I have searched SGL for a tutorial incase this has been covered so forgive me if it has. I've also searched the web in general and couldn't find a full tutorial to do this, so i have collated a couple of tutorials that make it work.
I have managed to get SkySafari to work with a £32 ish Raspberry Pi3 and the cable that came with my scope with a usb to serial converter - the same things you need for connecting to a PC. It allows me to control the scope using the SkySafari Plus app on my tablet or phone AND it creates a wifi hotspot on the Raspberry Pi so it doesnt have to be on a network to work. This also turns the pi into a natty mini wireless router which is handy if you travel since it gives you a private wireless network when plugged into hotel wired internet ?
I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT MAY OCCUR TO YOUR HARDWARE BY FOLLOWING THIS POST OR ANYTHING LINKED TO THIS POST
It takes about 30 mins to do the tinkering, make sure you use the latest LITE version of raspbian.
Raspberry Pi 3 Portable power to it (preferably) Raspbian Lite Image file Appropriate cables to connect your Telescope to it via USB Computer connected to network Network cable to connect Raspberry Pi for initial setup A GoTo / Push To etc telescope mount compatible with SkySafari Plus / Pro A nice case for the Raspberry Pi
You need to know a little about accessing the Raspberry Pi by SSH.
For windows, use Win32 Disk Imager to burn the latest Raspbian LITE image to a micro sd card. Open the card on the pc (called boot) and make a blank file on it called 'ssh' - no file extension. This enables ssh access automatically.
Stick it in your Pi and plug it into your network router and a power source.
Find its ip address - i log into my router by typing its ip address into a web browser and look at connected devices, there are other methods though.
I use a program called Putty to ssh.
There are many tutorials on how to do the above and it isnt as hard as it first seems.
I used 2 tutorials to do this and i will link to them directly as the original authors explain it better than me. The first one is muuuch longer than the second which is just 3 steps so bare with it.
When the first tutorial suggests a reboot after the upgrade, DO IT! Then ssh back into the Pi and continue.
Don't bother rebooting after tutorial 1 either.
Tutorial 1 - Turn Raspberry Pi into a portable wifi hotspot
See 'CONNECTING' after doing step 2 in the next tutorial to actually connect to the scope as what you have just done changes it a bit.
Tutorial 2 - Make it talk to SkySafari App and the 'Scope
You can now unplug the pi from your router. Plug your USB to serial adapter into the pi, your telescope cable into that and connect it to your scope as you would do with a pc (mine is into the AutoStar hand box) and use it as a stand alone adapter just like the £200 SkyFi adapter!
To connect SkySafari to the pi you simply connect your tablet or phone to the pi's network like you would any other wifi network, i called mine Scope, connect using the security key / password you made up in tutorial 1. Open SkySafari and follow step 3 in the second tutorial but with IP address 192.168.0.10 - the port is still 4000 (unless you changed it)
If you are at home and your cable is long enough to reach your router you can plug the pi into that and use your home internet too - which you cant do with the SkyFi adapter!
I am going to shorten my serial cable to make it a neater package, i can always solder new plus to make an extension if i ever need one.
I am also working on finding out how to make it share usb internet so a 4g dongle can be plugged into it when out and about since when you connect to the pi's wifi in the field you will not have internet on the device connected to it.
Also the Pi could possibly be used for imaging or tracking, someone on here will probably know more on this.
So my birthday just past so money to splash on astro stuff , i will have my 1000D modded by juan at cheapastrophotography and also have ordered an autofocuser from deepsky dad https://deepskydad.com/autofocuser i know they can be done DIY but this is a neat package and costs about the same as a SW autofocuser and a hitechastro focusmaster and i`m no electronic wizard and pavel seems to have a good product and works with ascom and confirmed it works with APT i will update in a few weeks time when hopefully i will have received and tried out .
