Help with lens

[ Edited ]

So I just bought the Canon EOS 2000D 18-55mm f/3.5-5.6 and I want to get into some astrophotography. I'm looking at two lenses right now and I need help figuring out which one to get because I have no idea about cameras and lenses. 

 

Here are the two lenses:

The first one is a bit  more expensive than the second one, so I just want to know if there is a big difference and if the second one will do a good job. Right now I'm most likely going to try to take pictures of the moon and maybe Jupiter and Saturn, but in the future I might invest more and get Sky-Watcher Star Adventurer 2i Pro Pack for some long exposure shots and try to get some deep space pictures of nebulas. Will the second lens be able to produce nice pictures of planetary objects and deep space objects? Or should I spend the extra money and get the first lens?

Welcome to the forum.

 

The first lens isn't very "long" at 135mm. The Canon 75-300 is not one of Canon's best efforts. It's low priced so they can offer it as a kit lens.

 

If the Rokinon is in your financial range then I woukld suggest this lens:

 

Telephoto Zoom | EF 70-300mm f/4-5.6 IS II USM | Canon USA

If your budget goes higher here is a longer option:

Re: Help with lens

You probably could not have picked any two worse lenses for astro work.

 

Rokinon does make a few lenses that a lot of guys use for astrophotogrphy. The Rokinon 14mm f/2.8 IF ED UMC Lens For Canon EF is one. For Moon shots the Tamron SP 150-600mm f/5-6.3 Di VC USD G2 for Canon EF can be a good choice. I prefer it over the Sigma C model as the big Tammy is slightly more sharp. But either will do nicely. For nebulae you need dedicated astro gear.

Re: Help with lens

Look at my images of the recent conjunction with my 150-600 mm lens.

 

You will need at least 800 - 1000 mm of FF focal length to see what you want to see with any detail.
