Dear Professor Mike Merrifield, I received my Messier Certificate (and Pin :) ) in 1994, and while I observed/recorded/drew all the required objects, I have always wondered about what you spoke about concerning M102. This is the clearest explanation I have ever heard of M102 and the mistakes/reasons concerning the errors in recording it. Thank you so much Professor Mike Merrifield for this contribution and the Deep Sky Videos as a whole.
drmoynihan i was out sketching tonight and decided to go for m102 in draco, I’m about 3/4 through sketching the messier catalogue. Anyhow m102 didn’t appear on my jumbo pocket atlas star chart. I guess the person who made it had enough controversy to leave it out entirely!
@@isaacjohnson8752 Most believe M102 to be NGC 5866, known as the Spindle Galaxy. Hubble took the most famous picture in February 2006 and it really does look like a spindle. I was somewhat aware of the controversy on August 21, 1993 when I recorded M102 in my Messier Log. Using a 8" Schmidt-Cassegrain, I was just going for the Pin and the Certificate and made sure I saw and recorded all of them. What really helped was to have some very experienced friends around me who were members of Portland Oregon's OMSI/Rose City Astronomers. Even though were have moved all over the place, they are still my friends and we try to make sure to get together at least once a year.
After all the Nottingham videos I have seen, professor Merrifield sticks out as one of the most inspiring, consistent and down-to-earth presenters. It's a real pleasure to watch and I hope he will continue after the Messier catalogue has been completed.
I like that simplification of calling the 'dust,' soot. It intuitively conveys the processes involved in a more relative terrestrial context. I immediately associate the term with smoke. Then associate the idea that this is the product of 'burning' stars and all the extra byproducts that result from them. Thanks for the upload. -Jake
I was actually out on my balcony last night observing NGC 5866, actually my first time observing this DSO. From light-polluted skies, I hunted around and finally found it; I confess I was actually looking for NGC 5906. I had never really considered M102 before. Bright and pleasing to look at. I can't wait to go see it from my dark-sky site. Also, the hope of resolving that fine dust lane is just one more reason to go buy a higher-power eyepiece!! Dear DeepSkyVideos: You still haven't done one on M94, the Croc's Eye galaxy. This galaxy has some features that definitely deserve some attention. Why does it have that ring? thanks :)
always fun to see those human errors creep in. I often see historical heros like Messier described in terms of accomplishments - cataloged x celestial objects, invented this or that technology, received this or that award. it's surprising and amusing to learn that as early as, what, 1800? authors already had the experience of a time crunch for publishing.
A question. In various videos I have encountered statements about the size of andromeda galaxy that are wildly at odds with one another. From 'much smaller than the milky way galaxy' to 'two or three times bigger than the milky way´. This is the closest galaxy to us! If we cannot tell its size, how much can we believe about all the ones much farther away? Can prof. Merrifield and/or Dr Gray comment on this?
What are all those quite evident disk like shapes _around_ the galaxy? They look a bit like denser rings of more concentrated material, orbiting a personal trajectory. Is it just an effect of the telescope? Or was he referring to these during his explenation, and I misunderstood thinking he was referring to the light blue gasses on the outer edge of the Galaxy?

This video is way too short. I could listen to this guy talk about the history of the Messier catalogue for like 2 hours.
Agreed. I would love to take him out to dinner and talk astronomy, I'd be in hog heaven!
So Messier started out very neat, then near the end he got a little messier.

+1 internets.
Man I was missing professor Merrifield so much. Give this man a chance to speak more on this channel!
I will never unsubscribe this chanel, it made me closer to stars, to deep space.

Excellent! I wrote an article for Sky and Telescope a few years ago about the identification of M102 and came to the same conclusion.
Wow this series has been going on for a long time! Good to still see some videos
Checking the website there's 30 they haven't done yet so if they stick to about one a month that's nearly three years left.
That Hubble image is amazing!
Nice to see new videos coming out . Thanks!
Another wonderful, fascinating video. Thanks for producing these. Also points out again the treasure that is the Hubble Space Telescope.
Here to say this shave and haircut are primo, professor.

Dear DeepSkyVideos:
You still haven't done one on M94, the Croc's Eye galaxy. This galaxy has some features that definitely deserve some attention. Why does it have that ring?
thanks :)
love these videos ... makes me want to go back to school all over again!

Right? This is kind of like a science bloopers reel. =-)
Noooo, too short!!!
How much change would there be in viewing objects after 250 years? Apart from better optics are the relative positions still much the same?
When you say thin it would be good if you gave a measurement so that we can get a perspective on the size of the galaxy.
Thank you for these awesome videos!
Thank you Prof Mike! Nicely taught!
Beautiful.
it baffles my mind how many galaxies you can see at 3:34
Are you saying the Messier catalogue is........ messy?
No, it's messier than that.
Apparently Messier was in a funny mood and put an Easter Egg into his catalog ;-)
im not sure ive ever heard a galaxy being described as relatively quiescent
Hey! You guys are alive!

When I saw the title I thought we were going to get Matt Parker doing another Humble Pi promo :-)
This was the same Méchain who with Delambre surveyed the line that determined the original length of the meter.
Is the extended 'glow' surrounding the galaxy in the wide-field images of NGC5866 gas, or stars, or what?
Streams of stars
"Glow" of distant galaxies is always stars. Since space is a vacuum there is nothing there that could cause glow.

Actually there is nebulousity given off from nebula as well. 😋
0:18 Mesier looks a bit like Anthony Hopkins in the Silence of the Lambs.
good to see prof merrifield again, but it was a bit short. if only he didnt talk so fast :-)
Even hundreds of years ago scientists were rushing to meet their deadlines. I feel some sort of kinship across the eons.
The day professor Mike finally got old was a Friday.
For the record, that's NGC 5866.
The moral of ths stroy is... If you're going to use grid lines, use a ruler.
Sounds like Messier had a few too many bottles of wine that night.
3:51 nobody's going to mention the residual dust clouds that clearly indicate that galaxy is spinning like a coin counter-clockwise?
yes. you.
Looks like it got messy at the end ...
How many Messier objects are there, 110? Are they doing them in numerical order? I forget. Shame this series, like the Universe itself has to end. 😢
They are doing them more or less randomly.

Which progress es faster?
Who won? Who's next? You decide!
