I had made a video about how to find Pluto, and why this time was a good opportunity to try and spot the little pla... uhhh - dwarf planet. Two weeks ago some of my friends who are part of the informal Chicago Astronomer group indicated this weekend might be a good time to try it. I put it on my calendar, and was not disappointed!
We met at Conway Observatory in Lowell Indiana. The skies are between 5.5 and 6.0 magnitude, NELM - well, overhead and to the south that is. To the north, the glow of the city and urban sprawl still block stars down to 3.5 or 4.0 about 40 degrees and below. But we weren't looking north. I had researched how high Pluto would be above the horizon: It was to be 20 degrees by 10:45, 25 degrees by 11:45, and culminate on the meridian at 29 degrees around 12:45 or so.
Being a glutton for punishment, I started trying around 10:30 or 11:00. But, I had something going for me: VERY transparent skies. It took about 5 minutes of searching, and using averted vision, but I was 80% confident I was seeing Pluto very near a small triangle of stars. My friend Paulie said this was a special night, because he didn't know anyone who had ever seen Pluto with their eyes before. I asked Paulie and Bill to look too - both are experienced observers of faint objects themselves. They said they could see it averted too. This was exciting, because Conway has a 16" SCT there. And I had both the chart I had made from Stellarium, and another one I had made from this star chart down to magnitude 14.5, that I inverted to have black stars on a white background, and then printed.
About 11:30 or 12:00, I don't know for sure as I wasn't paying attention to my watch at that point, we decided to look for Pluto with the 16". Sagittarius was definitely a lot higher at this point, and the Milky Way in that part of the southwest sky was such a different view than what I get from my house: The clear "steam" off the "Teapot," and the Scutum cloud just glowed with such an obvious light that it was difficult to not imagine the arms of our galaxy wrapping around our tiny solar system. I had never used the 16" scope before, and we were starhopping our way there. Plus, my reflector had inverted the image and reversed it left to right; the SCT had it corrected up/down, but inverted left right. And, I didn't know the field of view.
I struggled for a bit, trying to find the same field. Finally my friend Paulie showed me how large a field of view I was seeing, based on his trying to find it two weeks earlier. With that, I had it in about a minute or two. It was still faint - surprisingly fainter than I expected, given the large jump in aperture over my 10", but there it was - direct vision, right in the spot where it had been with my Dob.
Before I even left to go over there, I had stopped by the fast food restaurant where my daughter works before I left. She asked what I was doing, and I told her I was going to try to see Pluto, even though it's not a planet anymore. She made me smile when she said, "Well, I learned that the solar system has nine planets in school, so it's a planet Dad." She's a great kid, is she not? Hard to say which part of the night was the better highlight - that or Pluto. 
So with that, I guess I've finally seen all 'nine' planets.

Great video and nice job on Pluto! I keep meaning to look for it but always get lured away by other objects. Curse them and their fancy large apparent size and magnitudes! I was kind of bummed about the Pluto downgrade, but the ruling makes sense.

I observed Pluto in July of 2010, when it was in the dark nebula Barnard 92. This was in my 16" scope. Awesome feeling of actually seeing it!

Hi.
Now you make me very excited to find it as its my goal this year to find Pluto. Sadely, I missed the chance to see it this month in my black zone dark sky due to weather and work. Next month is my last chance this year and for sure I will not look at any other object until I find Pluto. You make me feel I'll be able to see it in my C14 as you have seen it in your 10" dob. Last month I saw easily a 13.6 mag galaxy in my scope direct vision, so Pluto should be an easy target but I really don't know ?
You are lucky and I envy you. I'm so eager to see it for the first time of my life. I'll print lot of chart at different FOV to be sure I make it. Tell me. What kind of magnification I would need ? My 31mm give me 126X with the largest FOV, but if I use higher magnification, I'll loose some light and reduce the chance to see it no ?
Thanks for your report. I'll be back here next month with my own report.
Andre.

That was definitely the time to see it as it was easy to pick out due to the lack of stars in B92. I made sure my two children, who were 10 and almost 7 at the time, saw it too. It was amazing seeing it with our own eyes even though it just looks like a faint star. We saw it July 5th if I recall correctly...

Indeed it was a perfect time to view Pluto. Quite thrilling, to say the least!

Congratulations! Finding Pluto with my 12.5 inch, F5 Dob is too difficult to even put on my bucket list. I have yet to even see the Horsehead--but I will some day.

Under a reasonably dark sky, your 12.5-inch Dob should show Pluto without too much trouble -- especially at your latitude. It's a lot harder up here in Massachusetts!
In a lot of ways I would say that Pluto is easier to spot than the Horsehead. But that's a ridiculous comparison -- it's totally apples and oranges. The Horsehead is all about dark skies -- and a hydrogen-beta filter helps immensely. With Pluto, aperture is paramount -- though dark skies obviously help too.

Magnification (with good seeing) helps a lot, too, with Pluto. And the trick is knowing you're seeing it even if it should be plainly visible under the conditions and equipment.

Congratulations! The dark sky area I have access to has a bit of muck low in the south so it would be quite the difficult target for me.

I saw Pluto about 10 years with a couple of friends using a goto 12" SCT. Having a good star chart and a large goto scope made identifying Pluto in the eyepiece an easy task.
We had a discussion after the sighting trying to agree on the total number of people ... alive in the world today ... that have viewed Pluto through a telescope. We came up with 4,000 +/- 3000 as a guess. Anyone care to express their opinion on this number?

I love the error bars, skyguy. I would guess your number high, but really have no idea. I suppose it might be that high as I've found it in a scope three times and each time I was able to show it to a couple of people who are in no way astronomers.

My bucket list contains both apples and oranges.

Observing Pluto is an awesome feeling indeed! Last week I spotted it in my 14", with some difficulty and a lot of patience & averted vision. This is a great time to track down it down though, as Pluto is close to M25 (and will be for the next month or so), which makes it very easy to get in the right ballpark quickly.

Asron.
I'm glad you made it with your 14" as its what I'll you next month. In which color zone you were to spot it ? I'll be in a black zone what should make it easier to see no ?
I'm so eager to chase it. That will be a nice challenge, a real goal to accomplish. Oh, what magnification did you use to spot it ? I did some star charts with four different eyepieces as 31, 20, 16 and 11mm.

Andre: I observed Pluto from a red/orange zone using 198x magnification. I imagine a black zone with a 14" will definitely increase your chance for success!

Oh well, I agree with you, I'm sure i'll be able to spot it. Thanks for the precious information.

Awesome!!!....and congrats! I did visually observe Pluto...in the mid-1980's.....I have the exact date in an old observing log....!!!!! I was observing with a friend's 16" reflector. It was an awesome feeling!!!!

Hi.
I join your group of persons having seen Pluto for the first time. Yesterday I went to my black zone site and found Pluto. Yes, I'm very happy now. I pushed the observation to almost the limit of my C14 seeing 14.3 galaxies for the first time. I also saw several stars around Pluto. They are all very faint in the scope and I had to use averted vision to see them, but I did.
Now I'll be able to compare different light pollution zones with this sight. I noticed a couple of reference point. Next goal now, pushing to the limit my Lunt LS152 in night mode.
Andre.

I disagree unless you have terrible skies. I spotted Pluto with my 8" reflector about 20 years ago. I was a challenge but doable.
