    I can FINALLY say with 100% confidence that I was able to locate 46P/Wirtanen. The last few times I've tried with binoculars, I thought I had seen it, but wasn't absolutely sure. Last night, no doubt about it. I could see it with averted vision from my Bortle 5-6 front yard. I could also easily locate it with a small pair of binoculars. I looks very similar to a nebula or a galaxy. I also managed another first last night and got a couple of pictures of a comet. The first one is a single 13-second exposure at ISO3200 using my Canon 750D and an EF-S 18-55mm lens at 55mm. The second image is 10x10s exposures with the same camera, lens and focal length, stacked in DSS and processed in Photoshop. I didn't really feel like getting out my Skyguider Pro and messing with polar alignment so I could do longer exposures, but maybe I should have. Still, turned out pretty good and I'm happy that I can finally say I've seen it and have the image to prove it. Tell me it doesn't look like a smiley face winking at you!

    From the album: Gallery

    46P/Wirtanen was discovered photographically on January 17, 1948, by the American astronomer Carl A. Wirtanen. The plate was exposed on January 15 during a stellar proper motion survey for the Lick Observatory. Due to a limited number of initial observations, it took more than a year to recognize this object as a short-period comet.(Wikipedia) SCOPE: Dob 10px Sky-Watcher 2200/4.7 EYEPIECE: Edmund Optics 32mm ELF LOCATION: Mammari

    I sketched this while laying back in a recliner under nice dark skies. The double cluster was an easy naked eye object so I included that. I used black A4 210gsm card, a white gel 0.8mm pen and a white colouring pencil.

    Cheers, I will have to set up, photo and then post.

    Actually it can happen over the course of one year or so. On Heq5 polar alignment scope there are engravings of exact position (I'll try to look up diagram online) that have year markers - correct pole star position changes in matter of 1-2 years - and shift is such that is more than usual visual PA error, or smallest movement that one can be certain there is good PA. As you see, there is slight "wobble" in pole star position in relation to NCP.

    A little short for a storm trooper isn't he? Sorry had to be done...Good luck with sale!!

    Basically I was looking to see more detail. I like taking video of the planets and stacking them. Should I look for a different tube design as I already have an RC for deep sky? Like I said, I'm really interested in lunar and planetary right now, as I have a new asi224mc camera. Also trying to stay in budget around $500. The 6" newt has been a good all around scope.

    Here it is in all it’s glory Now I’ve got a snap it’s back to the eyepiece!

    I had another go at this. This time with no moon and no light pollution filter. The star colours were much easier to process. Taken on 30th November with my Canon 450 Samyang 135mm F2 at F4 on the Star Adventurer, 146 30 second lights at ISO 400.
