Nice!

I like the 200mm view which also shows the Horsehead nebula... :cool:

no kidding. some lenses and mirrors can be insanely expensive. some of them are similar or exceeding laser grade stuff. not cheap, and big!

Yeah no kidding. My lens weighs more than my steel framed camera.

That is fantastic! I think for a 200mm focal length that's rather impressive!! I used a 600mm Tamron lens, albeit for only 4 seconds, without tracking so the result isn't even half as good. Excellent shot!

Here is my attempt. Sadly I don't have the ability to track, so it's all down to me

The hard part is that longer you go, the shorter the time you can expose for. With 600mm I wouldn't go much longer than 1/2 a second for sharp stars. Orion being surprisingly large, I like 200mm a lot.

Whatever you do though, stacking can help tons. Take 20-30 pictures and run them through deep sky stacker. It will irradiate noise allowing you to pull more details out.

This is where a motorized equatorial tracking mount will really help out. The key to AP is signal to noise ratio... you want as many subs as you can reasonably get with as little noise as possible per sub. The length per sub helps with "depth" of subtle details like nebulosity/dustiness.

Examples of longer subframe exposure times: M45, Barnard 33, M42, NGC 7023.

I'm really digging your posts, Isaac... keep 'em coming!

cheers! :beer:
