I find this field is one of the richest in the (northern) sky.

Retrying this with another (presumed better) vintage 135mm lens, an EQ mount and better PA, allowing longer subs.
Result is now much deeper, with IC405 (aka Flaming Star / C31) and IC410 showing nicely.
The field is also very crowded and may show all stars too bright, and with more obvious aberrations.
Compared to the short variant, the lens shows less coma but some "diagonal" astigmatism and irregular CA.

Glad with it however.

Gear: Olympus E-PL6 with M42 Pentacon long 135mm/2.8 at F/4 on Omegon EQ-300 tracking RA
Capture: 92 lights × 40s × 3200 ISO, master dark
Site: deep country 26km from Limoges, France
Sky: good (given bortle class 3, usual sqm 21.4)
Processing: DcRaw, Regim 3.4, Fotoxx 12.01+
