Fujinon 14mm 2.8 R $700 Rokinon 12mm F2 $300 Samyang 8mm 2.8 ii Fisheye $300 All make wonderful astrophotography lenses, with great coma correction. Will consider trades/part trades for Nikon FX lenses (manual focus ai or ais, or autofocus, dont need 50mm's), or potentially a mirrorless body, gimbal head. Could use some wides like the Rokinon 14mm 2.8, 20mm 1.8g, Rokinon 24mm 1.4. 250-732-1712 if texting is easier
