Below are some photos taken with DSLRs using a Series IV 'Stiletto'' to focus. Congratulations and thanks to all of the contributors! (Click on the thumbnails to enlarge.)

"The focuser arrived on Monday and I was able to use it with my 10D and Brandon 130 APO last night...The seeing was a 2/5 with boiling images but the focuser worked like a charm. Here's yet another M42--but I doubt I could have gotten this kind of focus (especially easily) with the camera viewfinder and LCD screen."

"I just wanted to update you on my use of the Stilleto IV now that I have had it for 2 months....We've had typical winter weather here in Colorado, ie the clear nights mean the jet stream is above. However. I've imaged with a variety of refractors both here in town and up in the mountains....Because I'm getting such bullet proof focusing with the Stiletto IV, I 'm stacking upwards of 1hour of exposures in 3 to 5 minute shots with a Canon 10D...Here are some of the recent results....I think the Stiletto is a definite plus particularly when you want to ditch the laptop (almost always....)

Attached is an image of M13 I took using my new Stiletto IV for the first time with my Canon D300. It was as easy as advertised. I just focused on a bright star with the Stiletto, replaced it with my camera, slewed to M13 and took the exposures. Great product! - Lee A. Zagar

Here is a wide field image of the Double Cluster. Note that all of the stars are in focus. Again, thanks for the great product. It really is quick and easy.
