I re-edited the shot. I wanted to see the tail more. I don't think the weather will co-operate this week to allow me to get back out. Plus the comet is getting further away....

I dumped the exposure by 1 stop during RAW conversion. I was originally going to try a fake HDR blend. But then I just took that file and ran with it. A custom curve layer in post to emphasis the tail resulted in some funky colours throughout. This is what I ended up with. We all like tail, right?

I am not sure why but I think of Jules Verne when I see this picture.

Can't blame you and Tail is WONDERFUL.

I gotta say I like your previous edit AbPho. This one looks a little over 'cooked' for my taste.

I totally agree with both of you. :D

Should I be exposing to the right more in my shots? I am currently stuck with 30 seconds exposures until I get an intervalometer. Many RAWs I have seen (by others) are much brighter than the ones I am capturing. I also wonder what detriment shooting at a much higher ISO would have. Would more images be required in the stack to reduce noise? What about detail loss?

What about bulb mode? I have an older RC1 and it will open the shutter with one click and close on the second click.

FEChariot:
Though you are right and with B mode you can take an image of long exposure time, as much as you want, but for DSS or likewise softwares, to stock images, each frame needs to have similar parameters to be compatible for stocking. It is next to impossible to manually seat and keep each frame of say 30-50, expose images, exactly at same time say 120 sec. That is why B mode, though useful for a single image, is not helping for multiple frames and therefore you need an intervalometer. BTW intervalometers are really cheap these days and you can get one sophisticated reliable one such as many Chines versions that are offered less than $15, that is significantly lower than Canon's TC-80N3 or likewise.

FEChariot, Ive got to second Samsen here. I have an inexpensive n-e-e-w-e-r (sp?) intervalometer that has survived heavy dew, freezing temperatures and ice. Celestron I really like the last picture you posted. I am going to try one more time this Saturday. It's been a lot of fun with Lovejoy.


Panasonic G9, Panaleica 100-400, Samyang 12mm F2 NCS CS, 7Artisans 7.5mm f2.8 fisheye, Panagor 90mm f2.8 Macro (OM), Sigma APO 2x DG EX TC, Tiffen aXent ND 3.0 (ND1000) filter, Olympus OMD E-M5, Oly 14-42mm, Oly 12-50mm, ZEQ25gt Mount, plus a few other lenses, extension tubes, and general mish-mash

Right Samsen I was thinking more about single image shots but great point.

It's on order. :) I've put a request to Sky Watcher to change their firmware so that I can use the Star-Adventurer as an intervalometer. That would be awesome. Since is comes with a camera shutter actuation port. The pre programmed settings are of no use. And their advanced firmware is currently tailored to other features/uses.

Got another op to shoot the comet last night - it is already raining again today and it is not yet light. I can just make out the tail between the head and the end of the streak (got several pix with streaks like this; this one is running more or less north-south).
Like my previous post this is a one-shot done with an 85mm f/1.4 lens at 1.4 and the 7D2. 20 secs at ISO1600. Increased exposures (did a bunch of bracketing) were redder with no more comet tail.

You actually have a long tail here but the image is a little dark to show it . You might post your original and see how it looks .

I tweaked it quite a bit in LR, the tail is barely there.
Thanks
Tom

Still lots to do in regards to gradient removal, but it's my best shot so far of C/2014 Q2.
