[BAA Comets] C/2016 R2 passing the Pleiades

[john_drummond at xtra.co.nz]

Hi Nick,

Nice image. It reminds me of C/2014 Q2 (Lovejoy) when it was close to the Pleiades in January 2015 – image attached (Canon DSLR, 105mm lens, f2.8, 1 x 5 min exp, 1600 ISO). Your image has R2 on the other side of M45 than where Q2 was in my image.

Regards

Denis Buczynski and I took this image from Tarbatness in Highland 
Scotland last night. Unfortunately, after a really clear day the night 
was quite hazy and we only managed to get a short stack in a clear spot. 
This is a 5x30s stack centred on 2018-02-09, 19:34 using a WO Z61 (61mm, 
f/5.9) and a Sony A7s at ISO3200. The FoV is 5.7x3.8 deg. I'm impressed 
how deep you can go in a dark sky with such a short exposure and small 
aperture. The Z61 is also very well corrected with nice stars all the 
way to the edge of the full-frame sensor.

It looks like we might get another chance this evening. When it is clear 
the sky up here is pretty much as good as I have seen anywhere and that 
includes places like La Palma.

Nick.
