Canon 1200mm f/5.6 lens!



Here's a great lens to go with your Canon dSLR to shoot the moon. It's got 1,200mm of focal length as well as a relatively fast f stop of 5.6.

This should just about fill up the frame with a Canon crop sensor (APS-C) camera such as my Canon 30D. With the crop factor of 1.6x, the lens becomes a 1,920mm lens. My Coulter is roughly 2,400mm with my 30D and can barely fit the moon in on one frame.

The price is a bit high, but for those with the money, it's well worth it!

Here's the B&H video of it on an outing.

Phottix Cleon II C8

The weather has been really lousy here around Washington, DC lately. I haven't done much astro or lunar photography. I did however, pick up a new wireless trigger release for my Canon 30D. It's the Phottix Cleon II C8. The name is too long, but besides that, it's very innovative and well thought out.

My old Cactus wireless trigger only had one function. A half press would focus the camera and a full press would take the shot. If you set the camera on continuous shooting, a 3 second hold would initiate as many shots as you wish until you press the release again. Handy, but functionally limited.

The Phottix Cleon II C8 (the C8 designates that it's made for Canon primarily through the cable connecting the camera to the receiver) has a ton of features.

First, it can be used without the transmitter. You are probably thinking, "WHAT? That would make it a wired trigger." That's right! The Phottix can be used as a wired trigger. I find this a very innovative idea.

Second, it has a flash shoe connector built into the receiver. This allows it to be placed on the camera in a very prominent and easy to see spot. The Cactus receiver just dangled off the side of the camera and would turn whichever direction it wanted so you couldn't see if you had a good connection. The Phottix can be turned either forward or backward on the hotshoe so that you can see the LEDs respond to the trigger.

Third, the trigger has 3 settings. The first is just as a shutter release. The second has a 2 second delay which is very handy since changing the delay on the camera takes much longer to set and undo. The last is a continuous setting. All you have to do to initiate continuous is to slide the slider into this position and the camera shoots continuously. Again, very handy in that you don't need to go to the camera to change this setting.

It's quite a nice step up and a very handy improvement in terms of features. There is more product information here:


(I have no relationship with Shasinki.com!)

There's also a very thorough review and comparison of the Phottix Cleon II and the original Phottix Cleon here:

9 Day Old Moon 4-4-09


It seems like ages since I last posted a night time moon shot. I have to apologize since we've been preparing for visitors for Spring Break and also for getting our taxes done early. Whew! The weather here has also been dreary and overcast for most if not all of the nights since my last post!

This was taken over last Saturday night. As usual, taken with my Canon 30D and Coulter Odyssey 1,500mm (13.1") Dobsonian telescope with a Baader UV/IR cut filter. I post-processed the image with Registax 5.

I hope to take and post more as the full moon approaches!

St. John's Church Steeple and the Moon!


It was a balmy 70 degrees on Friday so I took a late afternoon walk around the White House here in Washington. I had recently picked up a Canon EF 100mm f/2.8 macro lens so I wanted to try it out.

I walked by St. John's Church which is where Barack Obama attended on the day of his inauguration. I looked up and saw the moon and the steeple in an interesting position!

Scopetronix Maxview DSLR II


I had the opportunity of grabbing a much-longed-for Scopetronix Maxview DSLR II 2" eyepiece projection adapter from Astromart over the weekend and it arrived last night.

What a beast! This is the biggest eyepiece projection adapter I've ever seen! In the picture above, you can see it beside my Canon 30D with my 17-85mm zoom. The 1.25" adapter sits to the left. It supposedly will hold a Nagler 31mm eyepiece without difficulty. I can imagine! It reminds me more of a World War I hand grenade more than anything else. 

I've owned the Scopetronix Maxview DSLR 1.25" version when I had my 20D. You can see pictures of it here. The "II" 2" version is significantly larger than the 1.25" "I" version!

I hope to be able to use it soon. The weather is not cooperating. Very cloudy and rain predicted for tonight and tomorrow here in Washington...

Diversions Dance Company of Wales?


You're probably wondering what in the world Diversions, the Dance Company of Wales is doing in an Lunar and Astrophotography blog? :-)

Let me explain. A while back, I was contacted by Joe Fletcher who's the director of the company about using my "Full Moon at Perigee 12/12/08" photo for a backdrop to one of their performance pieces. I was thrilled and honored that one of my photos was selected. I just heard back from Joe that they started performing the piece, "Lunatics" a couple of weeks ago and that he will send me a DVD of the full performance once it comes out.

I received a care package with T-shirts for my girls last night and my daughter was very happy to wear it! Thanks Joe and Thanks Diversions!

Astromart.com and PayPal.com

I haven't been out under the stars much the past few weeks and thought about what I should blog about. I came to this the topic in the title because I love these two web resources. My astronomy hobby would be unimaginably hindered without them. I have become huge fans of both services.

Let me start with Astromart.com's classifieds. Back in the Summer of 2007, before I purchased my first telescope, I did a lot of research on the web for telescopes and mounts. I quickly came to the conclusion that this astronomy hobby was going to be EXPENSIVE! How could I possibly get top quality equipment when the top quality scopes were very expensive?!?!?

Using Google, Astromart consistently popped up as a resource I should think about. Unbelievably, I was very hesitant to plunk down the $12 lifetime fee to get access to the listings! 

Astromart is very smart in some ways. They don't give you access to the prices that the sellers are asking without joining. This proved irresistible to me and so hesitatingly, I signed up and paid my $12 fee. 

It has been BY FAR, the best $12 I've ever spent. Astromart (AM) has given me discount prices and access to the top equipment and rock bottom prices. Not only is it a great resource for getting great equipment, it's also a way to "try before you buy." In other words, you can buy something (if you know that the price is good) and try it for a while and if you don't like it, turn it right back around and sell it again at virtually no cost to you if you price it about the same as youas what you paid.

I started off by researching small refractors and decided on an Astrotech AT66ED APO. I waited for a great deal to come along and about 2 weeks in, my dream scope appeared on AM. I was brand new to the hobby so needed everything along with the scope. The package deal I bought included a AT 2" 99% reflectivity dielectric diagonal and a Stellarvue multi-reticle red dot finder for a total of $350 shipped. At that time, the telescope was selling new for $329 alone. The 2" diagonal was listing new for $150 and the SV RDF was selling new for $58. I saved $188 on my first purchase alone!

It has been amazing ever since. I've bought and sold more items then I ever thought possible. I started with no name or big name (Meade, Celestron, Orion) eyepieces and have ended up with almost exclusively Televue eyepieces at this point! They're all Plossls but they're very good Plossls.

My total scope investment is around $1,500, yet I've bought and sold almost $5,000 worth of equipment. With a little bit of skill, I've also been able to make a bit of a profit on some of the items I've bought and have been able to upgrade gradually along the way.

Besides astronomy equipment, I've also purchased camera equipment and tripods from AM as well. I've found that astronomy buffs sell their camera equipment at better prices then camera enthusiasts do! I LOVE Astromart.com!

As for PayPal, PP has made using AM and other sights a total pleasure. After using AM for over a year by paying for things through postal money orders and personal checks, I've switched to an entirely PayPal system without investing an additional penny! I first sold a couple of items on AM to fund the PP coffers. Once I had a bit of money in PP, I then purchased and sold more items using the funds entirely from PP. It has sped up the time it takes to buy and sell equipment by 100 fold. I used to have to make a special trip to the post office after every purchase I made to buy a postal money order and mail it off to the seller. The seller would then wait until they received the postal money order until they shipped the item. This would generally take about a total of 2 weeks from the time I agreed to buy the item to the time that I actually received the item. 

Now with PP, I can buy and sell equipment at a lightning pace. If I'm buying an item, I send the user the funds through PayPal, then the seller generally puts the item in the mail the very same or very next day. I receive the items within 2 or 3 days!

If I'm selling, I generally conclude a sale within 24 hours of posting it on AM, have the funds in my account in that timeframe and have the item shipped the next day. 

All this without spending any additional personal money except the funds in PP. This happens becuase PP lets you buy and print US Postal Service services directly within PP. All I need to do when I sell something is to head down to the post office with the package and drop it off since it's already packaged and paid for. I know this may be old news to some of you but this is a world changing service that I am now finally enjoying (like just about everyone else in the world!).

Enough about my two favorite web services for now. Off to do more telescoping and photographing!
