With the 30mm Ultima (60x) All three galaxies can be seen within 1 FOV. But this night is not good for galaxies and NGC3628 can only be glimpsed with averted vision. The 20mm TV (90x) darkens the background and makes the galaxies better visible, M65 and M66 are still within 1 FOV, but NGC3628 is too far away and remains a very faint elongated blob. Then I jumped into space with the 12mm Nagler... With 150x it gives the same FOV as the 20mm TV. The galaxies become better defined. Unfortunately M65 and M66 are not that close, so they sit on opposite sides of the field. The impression of "double galaxy" is lost at this magnification. One FOV away NGC3628 can be seen much better. With averted vision a long narrow streak of faint light shows up, a much better sight than with the other EP's.

Fourteen years ago when I arrived in Spain I noticed that you could actually see stars all over the sky and not just the two or three that a person could see in the skies over Chicago. I then bought a cheap chinese 80mm refractor and began the hobby of astronomy in earnest.

A few years later I moved up to an 8" Meade LX10 SCT. The 8" has been the largest scope that I have owned and also has been the only semi-large scope that I have ever looked through. Two years ago I had the idea of building a 12.5" truss tube Dobsonian. Being an engineer and also handy with tools I decided to have a go at building the Dob. Last year when I was in the states I took delivery of an excellent 12.5 primary mirror that a fellow in California made for me. The secondary and focuser were over the counter items that I bought in the states and I decided that this would be a good project for this last winter.

After the Christmas holidays I started buying all the material and began building the Dob which was finished about two weeks again when naturally the weather turned bad. 

Last week I had the chance to get out on two marginal  nights to try out the new self built scope. The first night I had to work for a couple of hours to adjust the lenght of the tubes to get into the area of focus. The second night after a quick collimation I was ready and a little nervous but the Dob funcioned to almost perfection. The seeing was poor but I had no trouble with Castor and the trapazium in Orion. I then went to Jupiter and Saturn and noticed that the sight of these planets were much brighter than through any of my other scopes. I then wanted to try for the galaxy doubles M81, 82 and M65, 66. M81 and 82 are old friends and when I got these in the field of view of a 19mm panoptic I couldn't believe how much more detail of these galaxies I could see compared to the previous views that I remember in my other scopes. Not too surprising seeing that this scope with a good mirror is almost 150% larger in area than the 8" SCT. 

On doubles, the Zeiss Telementor gave a much better resolution of Castor than the Dob which is affected much more with the seeing. The Dob will be better for the dim deep sky objects and the Telementor and the TeleVue 101 refractors will be the work horses for the moon, planets and the doubles. I am very happy with the results of the truss tube Dob and I realize with better collimation and seeing I will have a real gem. I have not caught up with Eddy in Australia in size yet but who knows what I might get myself into next.
 

The DX-8263SL camera is really amazing, Just a little post processing and viewsthrough the C8 are better than anything in the Bigdog visually. Double the aperature for $250! best deal in the cosmos!
