Were you using auto focus or Manual, if manual, you find that most lenses will focus a tad past infinity and you may need to bring it back a tad ? I tried a few positions with an old film camera yrs ago and finally marked the sharpest point on the lens for future reference ? Hope this is of use ? |
Yes, I went out today with the 50mm and checked it out , focus is just before the infinity marker on the lens barrel. Since I'm not deep sky observing, a touch will be used to be sure ;-)

For best results, you want to shoot before the beginning of astronomical twilight (about 1.5 hours before sunrise). Anything post-that and you'll lose contrast. It's great for landscape images, but, not so good for bringing out detail in the comet.
This is the problem I had last night -- I got to my location very early, but, the comet was so low that it was being blocked by cloud on the horizon. All I could see was the tail. 
Good luck tonight!

Yes, you right I reckon. I said to myself last night that it was a recon. Might not go tonight - I got to bed at 6am this morning, had a very broken sleep through to just after midday, but really dog tired, can barely keep my eyes open. Tried to get some sleep earlier and was just drifting off into deep sleep when my mum comes home from the hospital banging on the front door...she had her keys but decided it was more important to wake me up instead of using her own keys...*sigh*. Couldn't get back to sleep after that and gave up
I think it'll be too dangerous for me to drive given how tired I am. And it's a clear night too
