    If you're looking at Nikon lenses, the 180mm f2.8 ED (either the AF or MF version) is well regarded for wide open AP use. While it doesn't give you the image scale you'd get with a 500mm lens, f2.8 is 8x faster than f8.

    Pentax/Ashai/Takumar made a nice 500mm prime in the 70's with m42 mount that works wonderful. They can still be found for under $200.

    orion.JPGorion (2).JPG Took these two images last night. In Huntington Beach, CA. They came out very well considering the LP. I think my 55-250mm Canon lens, may work out just fine for now. Relatively short exposures because of lack of tracking around 5-8 seconds. And the highest ISO 6400. I do notice that the higher exposure times with the high LP tend to obviously, glare out the image with noise etc. The camera knows no difference. Between a high ISO setting short exposure. And low ISO long exposure. So we have some wiggle room.

    Those are beautiful.

    When it comes to tracking.... If you like to DIY, you can build yourself a barn door tracker. I am doing myself right now, I am just waiting for my motor to arrive. I can't wait to test it out. It cost me about 80$ to get all the parts.

    I am following this site:
    Double Arm Barn Door Drive - DaveTrott.com
    I currently only use Binocs
    Celestron Skymaster 15x70
    Astrophotography:
    Canon T6S
