Stunning images Tom,

I especially like the composite image showing venus's path.

Sorry to bother you, but I was just wondering how you acheive focus on the 12'' dob,I assume this is prime focus.I recently bought a canon 550d and tried to attach it to the scope via the t ring and 2'' adapter but could not achieve focus.My scope specs are 300X1500 f/5.

Once again,All your photos are ajoy to look at thanks for posting
Regards Orestis

Hi Orestis. I can only speak about the Sky Watcher Goto Dobsonian series where they all can reach focus with a DSLR at prime focus. I don't use the 2" adapter. With a 5x Powermate or 2x Barlow on the 1.25" tube focus is reached with plenty of room to spare. Hope this helps.

Cheers,

Tom

Excellent work Tom.

The video's are fantastic.

Excellent additions since I last looked. That high mag video illustrates nicely the illusionary black drop effect,

Great image updates Tom!

Glad you like the images and videos. Here's a pic of the business end of the setup used.

I had the scope setup in the garage as all angles were covered for the event from in there, and I could close the door whenever I was not imaging or looking. Also, there was no wind.

Here's a compilation of all full disc images taken of the event. I didn't plan on set intervals so I took them sporadically, when I could.
