Accessories for Astro Sony A7s (CentralDS)

[crea8iveart]

I want to start with Deep Sky Objects Photography and for that I already bought SkyWatcher NEQ6 pro. I have also decided to buy Astro Sony A7s (CentralDS). I already have zoom lens for Canon. Now I want help regarding other accessories purchase I will need for deep sky objects (mostly nebulas) photography. I want to setup everything without computer on remote location. Initially I want to go with wide field to experiment first month and later I will buy the Refractor too. So all suggestions are welcome regarding purchase.

- Standalone Autoguider for Sony A7s ?

- Finder Scope

- Cables to connect

- Any adapters , rings etc.

- Refractor

There's only 1 shop locally here in Dubai which is quite new and dont have all the equipment available. So most of my purchase will be online through website. 

Thanks in advance!!
