Hi. I need some advice in buying my first gear for this hobby. I have 500usd to work with and plan to observe deep sky objects. I also have a d850 camera, so i was thinking i could try some astrophotography too. From my brief research, i should look for a Newtonian telescope and an equatorial mount. Is there something i am missing (what do i need to attach my camera to the telescope?) and is 500usd enough or should i save up a little more for better gear? If anyone has recommendations for gear(links would be great), please let me know as i have no idea what i should be looking for and where i should buy them. Thanks.
