HF39 and the Red Spider Nebula

Howdy
After the bad weather surprisingly clearing, got some imaging done.
A little planetary nebula near Eta carina looked like it was worth trying for, especially as Star Atlas Pro reported it to be Mag 9.29 H beta, and sure enough it was surprisingly bright. I did 2x 10 mins ISO 400 with the UHCS filter.

Next object is the Red Spider Nebula NGC 3537 in Saggitarius. Oddly its fainter (mag 13) yet has an NGC designation whereas poor old HF39 does not.
2x 10 mins also, UHCS filtered
Both shots with 10 inch F5.6 scope, hand guided. Both images here are full resolution crops from the centre of much bigger images. Minimal processing done just the standard dark subtraction etc, in Iris and Photoshop. Taken with modded 350D camera
