Shapley 1 and VBRC7

Unexpectedly it was clear last night over Newcastle with cloud all around but here So did some imagine, chose planetary nebula Shapley 1 in Norma. Its possible to fit in a much fainter and slightly larger planetary called VBRC7 which I see seldom done.
Image is 11 x 15 minutes ISO 800 with Baader UHCS filter and 10 inch f5.6 newtonian. EOS Ra. I was still able to find suitable guide stars even though the guider looks through the filter, but the coma corrector ensures nice sharp guide stars.
