Those are beautiful! Hope I can get something like those in the future 

If I have a budget of around $300 for a new lens and I already own a Nikkor 50mm f1.8, what would you guys recommend as a worthy upgrade for AP? 

Still can't pick my jaw off the floor, this is just absolutely amazing

Astronomik have a clip in filter system that will work with any EF Canon lens but not the EF-S series.

I have an OIII filter but never used it as not sure how useful this would be on wide field targets.

Looks like a neat little addition, sadly I have a Nikon and that system is specifically for Canon 

After a quick google search I did find this:

"Gerd Neumann at Astronomik informs me that they are working on a clip-filter system for Nikon bodies that should be ready for sale by late summer." posted on a different forum in October 2013 

Can't seem to be able to edit my last post so I'll make a new one..

One more question that I have, is there such a thing as Narrowband Filters for Camera lenses? Because the only ones I can find online are 1.25" or 2" for telescopes.. Would they not work with a camera and that's why they are not sold, or am I just not searching right? 

If you are not using an accurate mount keep the focal length right down and you'll get nice results. The longer the focal length the better your guiding has to be. I like lens imaging and images. This was autoguided and with a CCD camera and 60 hours of exposure (6x10 hour mosaic) but the lens was a mid range Samyang 85.

All credit to this lens.

Wow, beautiful! Please excuse my ignorance, but what object is that? 

Also, did you use some kind of a filter to bring out those reds? H-alpha or something like that?

I do have an old Nikkor 50mm f1.8 prime lens, gonna give it a go with that and see what I can get 

How far can one get with only a camera, maybe a DSLR with a reasonable size telephoto lens, and some form of tracking (maybe a eq mount or a barn door tracker)? If the tracking is good, could one equal the quality of pictures taken through a telescope, at least for DSOs?

Is anyone on here into this kind of photography? If so, please post your photos, show us what kind of pictures are possible with a simple setup like this!
