I ordered it online through Amazon. Can anyone come on a video it'd be great help if you can guide me through the process.

This is my first telescope it just arrived two days back..all this alignment and stuff is so difficult.
Yes I think it's pretty much in the center.
Should I contact the company or something?

It does look like the rotation of the secondary mirror is a bit out. What collimation tools (if any) do you have?
I don't have any as of now. Those circles in the middle should they be one on top of the other?

Hi @Rishabh and welcome to SGL.
Looking at your attached images it does kook if it the collimation is out of sync. I think you are supposed to see the mirror clips in the reflection on the secondary. Did you have the camera/phone dead centre?
At the back of the OTA there are three sets of two screws to adjust. One of the screws does the adjustment and one does the locking. Though I am not sure which is which. You will need a collimation tool: a 'cheshire' collimator, a collimation cap or a laser collimator. (note: if using a laser collimator, you will need to make sure that it too is collimated). A collimation cap fits in the eyepiece holder and should be more or less accurate. A 'cheshire' collimator is usually the preferred tool by many die-hard amatuers.
There are tutorials here on SGL and elsewhere on the internet. Search for 'Astro-Baby collimation' ...or something like that. Other SGL'ers will advise what is the best method, as I have two catadioptrics and one refractor.
Thanks for the reply. I found this video on YouTube
It shows how to make a collimation cap. I'll give this a try. I don't have any collimation tools for now. And I'm not sure whether my phone was in the centre or not either
Those two circles in the middle.. should they be one on top of the other?

Eye piece projection focusing problem
in Discussions - Cameras
Posted
I have a Meade polaris 127eq, I recently got a eye piece projection adapter. When I try to focus using the 26mm eye piece it works fine but when I insert the 9mm or 6mm eye piece I'm not able to see anything (tried increasing the iso).
When I focus on a bright light nearby with the 9mm I'm able to see that light on the camera, but with planets or stars it doesn't work.
Attached image- the adapter and the t ring for nikon.
