Last night, with my Borg 107FL and a Baader Hyperion 2.25x Barlow, I took this picture (single frame with Canon 650D) of the Double Double Epsilon 1,2 Lyrae (If interested, you can download and enlarge the pic):

Thank you very much for your kind comments.

 

For more than 50 years, I was a purely visual observer (and have always been fascinated by double stars). But now - in my old days (I’m 67) - I started (a few weeks ago) to do astrophotography with a digital SLR camera and my scopes.

 

For the picture of the Double Double, I took 120 frames with my Canon 650D:

 

ISO 12800 + 1/500, 1/250, 1/125 and 1/60 second exposure time (10 frames each)
ISO 6400 + 1/500, 1/250, 1/125 and 1/60 second exposure time (10 frames each)
ISO 3200 + 1/500, 1/250, 1/125 and 1/60 second exposure time (10 frames each)

 

The linked photo of the Double Double (ISO 3200, exposure time 1/125 second) is the best of these 120 frames. Obviously, the seeing was excellent during this 1/125 second. I just had the luck of the beginner!

 

On the same evening, I also took 120 frames of 52 Cygni (mag. 4.2 / 8.7; sep. 6.0"). Seeing was not so good during these shots. Again, I got the best picture with ISO 3200 and 1/125 second exposure time. If you are interested, you can find this photo here:

Ulrich, very nice images - both of them!

 

Thank you for sharing the details of your camera settings, too.  I am just beginning to dabble in astrophotography and find it helpful what settings people are using to capture their images.

 

Clear skies,

 Mike

Ulrich:

 

Nice images.  :goodjob:

 

Astro-photos generally do not represent what I see in the eyepiece. With the extended exposures and broad spectrum used for deep sky, they represent a different world.  And the planetary photos, the video capture and noise reduction/stacking processing greatly enhances the view.

 

But double stars are an exception, photos like yours are a good representation of what I see in the eyepiece.  They capture that elegant simplicity of a double star.

Very nice image. And I’m happy to hear you’ve discovered a new (to you) way to see an old favourite.
