Messier 67 Open Cluster

I have started sketching the Messier objects with the Orion dob, I figured it would be a fun way to earn the Messier Observing Pin from the Astronomical League. I caught this cluster earlier this month and boy did I enjoy it. This is a cluster that gets overlooked by so many other grand clusters out there such as M45, The Double Cluster, Messier 103 and The Wild Duck Cluster. Messier 67 just seems not to get much loving. Well as I write this there is a thread on CN that is asking about open clusters and what are favorites of the readers, ironically someone mentioned Messier 67.

So what is it that makes Messier 67 a nice one. Well it is pretty easy to find (see this chart). It is also pretty bright, even visible to the unaided eye in dark skies, easy with binoculars. And when you put a scope on it, using lower power the cluster has lots of bright member stars plus lots of neat faint ones. It also has some dark “lanes” where there are no stars. To me it seemed the stars seemed to go off in directions in clumps. I also thought there were a few stars that hinted some red color... take a peek and see.

Messier 67 is located in the constellation of Cancer. It has a apparent magnitude of 6.1. It is one of the oldest open clusters, and may contain some blue stragglers. For professional astronomers, M67 is interesting because of that.

So get out there and check this cluster out!

Well... Because App Lists Are So Cool Right Now!


The March issue of Sky and Telescope has a list of apps that many of their editors like. Well I read over their list and some I agree with some I don’t. So for this bonus blog post for January I thought I would tell you what is on my iPhone 5c as of January 31, 2015.

Sky Safari 4 Basic.... This is my app that I use for when out observing with binoculars or wanting to know where a comet might be before I go out that next morning. I downloaded this to replace Stellarium mostly because this app is way more powerful and frankly I was really miffed that Stellarium started charging money for their app in the App store. Sorry just don’t think it is all that good for the price, though nice if free.

Gas Giants... Basically tells you where the moons of Jupiter, Saturn, Uranus and Neptune are. I like it can be done with telescope orientation. The eyepiece view is a little lacking though.

Jupiter Moons... I got this because Sky and Telescope puts it out, does what Gas Giants does, but I like the presentation a little better. Same goes for Saturn Moons too.

Mars Atlas.... A really cool atlas that will show you what Mars looks like in your scope when it is near opposition. I would say this is essential for figuring out what the dark features one is seeing.

Lunar Atlas.... Same as Mars Atlas but with the Moon. Obviously more useful since the Moon is more observable then Mars.

Satellite Safari... Basically like Sky Safari but focuses on satellites. Really cool, though it can be a little limited to due it’s database.

Sky Week Plus... Another S&T app. Nice. Gives a good event or two each night to observe.

SkyGuide.... Beautiful. Was a free download from Pick of The Week. Really glad I went to Starbucks that week. I use it from time to time.

Star Atlas... Meh, it is okay. I am a little disappointed with it. I was expecting more, but when you need an atlas on your iPhone it is okay.

Orion... All it is good for is downloading their current catalog. It is nice time waster at work though!

NASA... Just get it, keep up with the space program.

ESA... Same as NASA, just applies to Europe. Both apps let you watch launches live though which is cool.

APOD... Astronomy Picture Of The Day. Enjoy the pictures. Sometimes videos won’t play though.

Exoplanet.... Really cool to keep up on discoveries, though the push notifications can get a bit annoying.

Moon Map Pro.... What I like with this is the LRO images. This coupled with Lunar Atlas to me should be a staple for every observer.

iCSC... This is the new version and it is really good. It can be a little slow to update and the set up took it a couple of times to remember my favorites. I so prefer this to Scope Nights which I know S&T has talked up so much. I actually liked Scope Nights when I first got it, however when the developer updated it and most of the features became only available if downloaded for a fee. Sorry but that isn’t the way to run an app and well the comments on the Apple site reflect that! The Clear Sky Clock deserves a good app and this is it.

So those are the apps I use. I am glad for all of them and they all serve a purpose. If you have any specific questions leave me a comment and I will be glad to answer you.

In Praise of The White Light Solar Filter

One of the things I am very thankful for is white light solar filters. They are available for purchase for most types of telescopes. The filter can come in various forms, but all fit on the front of the telescope. Any filters that screw into the eyepiece of your scope you should not use for safety reasons.

I ordered my solar filter from Orion when I ordered the telescope. The one I use is made of Baader Solar Film. The film is cut to size and put into a cell and it just pops on to the front of the telescope. It makes for easy viewing of the sun in what is called white light. The white light image of the sun will show you sunspots which you can track across the disk of the sun. The white light image is the same as that as the solar telescope at Kitt Peak National Observatory, however that is a dedicated solar telescope that uses a projection method. In white light you will not see flares or mass ejections from the Sun. That requires a dedicated telescope that sees in "Hydrogen Alpha." These dedicated telescopes run over 500.00 for a small basic one and top out in the thousands of dollars for a top of the line rig.

I really think white light solar filters should be in every amateur astronomer’s arsenal. You don’t need a large or expensive scope to use one. The filter themselves are pretty cheap too. The one I purchased was about $50.00. A white light solar filter would be a good thing to get for a old small refractor that you may not being using any more OR to take with you for long multiple night star parties so you have something to do during the day. A smaller scope in my opinion would be best for a solar filter just because the seeing is usually not great in the day time... however you don’t have to deal with dew or really cold temperatures either. To me that is a win-win right there.

There is also a Sunspotter pin from the Astronomical League that you can complete.

In short a white light solar filter to me is one of those things everyone should have, it will get you out using your scope more. I know for me it gets me out there pretty much once a week using the scope!

Oh one last thing, I promised a post a month last November. I am sorry I didn't get one out last month. I was under the weather with the flu for a bit last month... so you readers out there (all 3 of you ha ha) will get a second blog post this month!

A big update! A big update!

So it is has been a while since I have updated the blog. A lot has happened. The LX200 I was using finally died. The RA motor system went out and I decided to part it out. Now today I have a new Orion 8in SkyQuest XT Dob. I am excited to use the dob and am excited that I have a scope that doesn’t have anything electronic to break. I am not going to make this blog a review since it is still early in the ownership, but overall I am satisfied... but there are some items that will be modified.

I have decided to start observing all the Messier objects with it as my first project. I have seen them all once or twice at least in my life but it has been years since I have used a scope without GOTO. I am going to enjoy star hopping and using charts again. I also got a solar filter and completed my first solar disk drawing.

I know I have said this many times, but I am really going to try and make this a monthly blog. I know it will be tough, but I am going to do it. I think making it a goal much like my observing projects will help.

So that is all I have for now but keep checking for there will be updates I promise.

(No really I do!)

Time for an update

Well it has been since last April that I posted a blog. Well in that time I have finished the Carbon Star Observing pin and moved to the Local Group Galactic Neighborhood pin AND the Double Star pin. Both pins of course being from the Astronomical League.

This winter has been horrid for observing. I did get out in January, but it is looking like February is going to be a bust. I was out of work last week only going back to work on the Friday before President's Day. I had Walking Pneumonia. I would not wish that on anybody. Not only did I miss some observing I also missed the Mercedes Marathon here in Birmingham. I have run either the Marathon or Half or Marathon Relay every year since 2005. It was hard breaking the streak.

So hopefully I will get some observing in. I am only a few observations into each pin. Hopefully the weather will get better soon. We have had more snow in the last four weeks then in the last 13 or so years I have made Alabama my home.

So wish me so clear skies and check back soon for some telescope stories!

S Aurigae

I was out recently observing, working on the carbon star list from the Astronomical League and came across this star as part of the list. It is a carbon star, variable and is in a pretty crowded field (I was using a 22 Pan in my 10in SCT).

However all descriptions I have found for this star say it is really faint, has no color and there is a orange field star that can be mistaken for it.

While observing, I found the orange imposter star quite easily. However finding S Aurigae was very tough, I was about to give up when I saw a little, faint star that was blood red. I was excited and did a sketch and logged the star and moved on. I made a note to look up this star when I got home and see what other observers have seen.

That was when I found one entry on CN of an observer seeing a very faint colorless star. I am seeing a blood red color and it is probably one of darkest red stars I have seen doing this list.

This star varies from around 8 at brightest to around 13.5 at faintest. If I had to guess it is around 12th mag. Also my conditions are rural skies (not super dark) and a several day old Moon was up.

The CSOG guide helped immensely in locating this star, however the pic shows the star near it's brightest, as does wikisky.

Anyway I know most folks like the faint fuzzies, but if you have a largish scope this little carbon star is worth hunting down right now in my opinion, esp if the color is variable based on how bright it is. I found fainter carbon stars tend to be more red.

S Aurigae
RA 05 27 07
Dec + 34 08 59

After posting on several observing websites, I did find some folks who had observed this interesting star. If you get out with your scope, try and catch this one. I do plan on coming back to later in the year to see if it is any brighter or (hopefully) not fainter.

Something Came In The Mail

Over most of 2012, I had one observing goal, to complete the Astronomical League's Globular Star Cluster program. On Friday February 15th 2013 my pin and certificate came in the mail. I am pin number 228, so yes 227 folks may be ahead of me but I am still very satisfied that I finished this pin.

Since the pin is done I thought I might write a little about my strategy and experience in completing this pin. My goal was to observe the Messier listed globulars and complete the the remaining targets with globular star clusters from the Herschel 400 list. I found that this was a very good strategy for the most part, however several of the challenge objects are in the H400 and H400II lists. When I made my observations I did not take the time to cross check the lists (oops!). So in the spring of 2012 I observed several of the challenge objects and did not log them as such. While this was a little upsetting once I caught the mistake in the end it really didn't matter since I enjoyed viewing those objects anyway. Had I logged them correctly I would have completed the program a little sooner. In the end my strategy worked very well being I observed all but one Messier globular (M79 for those who are wondering). When working the summer constellations that are full of globulars, my nights were divided by constellation. In May I observed in Ophiuchus and on one marathon night in June I observed in Sagittarius. I would also do one more observing run in August picking up a remaining 10 or so globular clusters. It wouldn't be till near the end of 2012 that I would take another stab at G1 after my two failed attempts earlier. I really think observing the globulars by constellation is the way to go. You get to see the bright ones and some of the smaller lesser known ones and get a good smattering of bright easy and smaller tougher ones.

For my challenge object I used the M31 orbiting globular G1. This object is listed as a challenge object in Small Scope Wonders by Tom Trusock. Thinking, I was using a 10in SCT with goto/tracking I figured this object would fall easily... it however did not. It would require three attempts to successfully log this object. Now I am going to hurt some peoples feeling when I say this, but many claim to see this object when they in truth do not. To successfully see this object you must split the globular from the two very close flanking stars. I would read on Cloudy Nights and other message boards people claiming to see the globular but never referencing if G1 was split from the flanking stars. Seeing a fuzzball in the place of G1 is not splitting the stars from the globular, one should see a clean split. Now it took three times mostly because the first time I tried I did not use enough power (around 150X). The second time I attempted the seeing was horrid. It would be the third time that I cleanly split the globular from the two flanking stars. Spotting this globular with the 10in SCT was a real treat and a lifetime goal completed. But there is more. The first night I tried observing this object I had the opportunity to look through a 18in Obsession Travel Dob. With the 18in splitting the globular was no task at all and G1 clearly does not look stellar in that scope. To me it looked like a fuzzy star with unrefined edges.

Now that winter is in full force, globulars are probably not on the minds of observers, however spring will come soon, and after my experience completing this pin I highly recommend it. Globular Star Clusters are beautiful in any scope, and this pin is pretty easy since over half of the objects of the required objects can be observed in the Messier list. I also want to say that this is not my first observing pin, however the letter that Bob Kerr sent me once he had certified my observations was one of the most personal and genuine letters I have received from any of the Astronomical League coordinators.

So wishing all you nice readers out there clear skies and eyepiece views of globulars... once we get through winter of course!
