  1. Shooting at lunch can be tough. A good hood or cloak to cover your focus area might help. Make sure its light colored on the top or it will heat up. Also, I've found it easier to tell when the image is out of focus. I'll usually rock back and forth between focus and out on both sides of focus and then find the mid spot. What type of filter material are you using? You might try some Baader film and a Green #58 filter. When taking the image put your camera in B&W mode. This will null out any odd green coloration and only show the contrasts. Best of Luck
  2. Hello everyone. Below are some images I've taken over the past few days. I used a Lunt 152 telescope and just got my Calcium module for it. Its a cool device and is based on their wedge design. It allows for over a 152mm aperture. The calcium device came with a visual back that allows for night time imaging or Greenlight imaging. I put a piece of baader film on the scope and got some GreenLight images.

    2011 - Caustic Mitosis

    Images from the 31st of July - Aug 3rd
  4. Exceptional detail Sheri. Those proms on the H-alpha disk were gone by the time the rotational view got around to Texas but the spots were a site to see. Well done.
  5. Nice color and detail on those images.
  6. I use a 2x Celestron Barlow head on occasion but don't really see an issue with it. However, on a few occasions I've noticed the brass retaining ring that holds the lenses in was loose. I check it now every other month or so. I am curious about how your 2.5x powermate works for you. The one I got a few years ago has a tapered front end where the lense is. The barrel on it is so long that if you put it in a prism diagonal, there is a chance the tapered end could scratch your diagonal if its a prism type. I think the newer type though are not tapered. Good luck with your new setup. Clear
  7. Hello Tom, For this setup I got a Lunt 60 front filter (non Doublestack type) and adapter to fit the filter to the front of the telescope, and a rear blocking filter. They make two types of front filter, one is for adding to an existing filter as a "double stack" filter and the other is a standalone type like the one I got. The single stand alone filter is rated by the Lunt group at <.75 angstrom. If you add a Double stack filter to the front of it the filtering is reduced to <.5 angstrom. These Lunt filters do not have a central obstruction in them like the Coronado filters do. In t
  8. Excellent details on these. I used to use an ED80 and loved it. It had a really good FOV for ccds. Clear Skyz,
  9. That's a really sharp full disk. Well done sir!!
  10. I just got my new Lunt front 60mm stand-alone filter with B600 straight. I will be putting it through the paces tomorrow morning if all goes well. Clear Skyz,
  11. Thank you. I sometimes take for granted the clear skys we have here in Texas. I try to make the most of all the clear days that I can. I have another video I'm working on that I took on the 4th. It should be a bit longer than the first. It was a really good day.
  12. I almost forgot, on this day I was also helping a friend figure out a good ISO/Shutter speed to use for capturing the Sun's full disk. I have a Canon XTI camera. I found that it isn't exactly the best for catching H-alpha detail but its definitely do-able. The thing I like best about the camera is its ability to take repetitive shots without the lag to write to the memory card. That's a big plus. Long story short I found that with my setup a 1/6th~1/20th shutter speed worked best and a good stack of about 75 make the image look pretty Juicy.

    2011 - Devil's Backbone Series

    Hello, this is my collection I call the Devil's Backbone. These images were taken 4/2/2011.
  14. Absolutely Killer Awesome!!!
  15. Hello everyone. Its been a busy month with little time to shoot the Sun but I did get out on the 3rd and 4th. I cobbled together a video of the large prom on the 3rd and will work on the one on the 4th soon. I recently have my solar telescope tweaked at Lunt Solar Systems and its really rocking now. Clear Skyz Solar Prom Video
  16. Some really excellent images. I like those long filaments you captured and the detail on the Cak images.
  17. I had a really good weekend. I did my two favorite things, shoot the Sun and make BBQ. I've been thinking my solar images have been sort of odd of late. Slightly blurred and the full disk seems sort of off as far as detail goes. I reasoned that it could be the collimation. I found a site that sells a handy collimation eyepiece for refractors and checked my 152. It was way off. When I went to collimate it one of the screws fell out. After an hour or pushing and pulling I finally got the lens on track. I checked again Saturday and it had slipped out just a little so I recentered it prior to gett
