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!

Seeing Red!

With the close of summer behind us, and the completion of my globular star cluster pin from the Astronomical League, I have started two new projects for more observing pins from the Astronomical League. The first is Carbon Stars and the second is Sunspotters. I have always been fascinated by carbon stars which I had sort of started observing earlier this year. Now with globulars done I can really focus on them. As of today I have done 16 of the 100 stars. So far the stars have been interesting with a couple of them being really nice. The Astronomical League has a list of 100 stars to observe whereas many other lists of them may only have 15 or 20. So while there are some impressive stars on the list, there are some that don’t really give the impression of the carbon star many astronomers might have. But is neat to see the differences in the stars, which I can even appreciate being just 16 stars into the program. Now the Sunspotter program is a program that is nice since it is in the daytime. I don’t have to deal with dew or cold weather! This program involves following the Sun for an entire 30 day cycle and also identifying sunspots and the features they exhibit. So that is all for now!

Globular Star Clusters!

I have been working on the Globular Cluster list from the the Astronomical League.. One thing I have noticed with it the Messier globular clusters are some of the most beautiful objects in the sky, well except maybe M107, that one was maybe the least impressive and there are some NGCs from the Herschel 400 list that rival it. That being said one nice thing with the Messier listed Globular Clusters is that they are bright enough for scopes of say 6in or 8in range to really show the details and characteristics of the globular cluster. With the 10in LX200 the objects really have some pop. I also have enjoyed studying the brighter NGC globular clusters where some really show some detail and others it takes a bit more work to coax detail out of. I have also attempted to observe some clusters that are a bit more tough such as the Palomar clusters and G1 in M31. I don’t know if I have a favorite cluster, I really do enjoy M3 and M5. I also have enjoyed rediscovering many of the lesser known Messier clusters such as M12, M14 and M92. It has been fun trying to classify the clusters then looking in the established research to see what the cluster has been classified as by the professionals. This project will hopefully lead to observing all of the Milky Way globular clusters of which there is at least 150 (I have seen 152, 154 and 157 so take your pick and understand it will probably change over the course of a year). So my advice is try and get out there and observe some of these balls of stars, summer is here and many of them are in full view!
