Hey Charlie, is that you in the picture? Gee, I thought of you as an older (60-ish) gentleman with a business man type look. Well, good thing I don't have a digital camera to take my picture. wink

Glad to see you're liking your Burgess Scopes. I've had my 1026 out for about 20 hours since I got it last January 29. I haven't yet tried to determine if it's 70mm or 90mm. It's given me nice views of M42 (the Trapezium area looked kind of like a dark Gerogia O'Keefe watercolor at 100X), M45, M44, and M41. Saturn has a nice almost 3-D look to it maybe because of the hint of the shadow on the rings. When Jupiter is high up (around 45 deg or higher), it shows 6 bands (including one on one of the poles). Last Saturday was "Moon Night" in which I spend 1.5 of my 2 hour session just looking at the moon and learning some of the features in it.

So far, I've been using the 1026 "as is" with the restricting stop still in. I'm going to take a little poll on Burgess Refractors to see how those owners who took out their baffles like them. I may use that to guide my decision when I measure the working diameter of the lens with stop.

Have a great night.

Mark, That was not me, that was my friend Jim. I don't know how to take you reply. I hope we are all friends here. Aperture is aperture you know. Charlie

Mark,

I removed the rear baffle and was very pleased in the additional brightness of the view. I'm really not sure what Bill Burgess was talking about in terms of a "yellow haze" around things. I've looked thru many acro's and it really doesn't look a whole lot different. I did have to break in the focuser a little and recollimate it as well. However, that took all of 10 min to discuss with BO and then about 10 min to fix. That and removing the baffle made the view of saturn go from fair to excellent. Best of luck with yours and clear skies.

Mark, I did a copy & paste of my answer on the yahoo group for the benefit of those here.

I did not like the restriction so I took the baffle out and flocked the inside with black felt from walmart.

With the Baffles out you will get what is to me a very intrusive yellow halo around the bright objects such as Jupitor. Saturn was less but still there. With the moon it didn't bother me. However I knew that would be the case before I took the baffle out. On Deepspace objects such as the Orion Nebulae or the Pleades there is no offensive color and you wouldn't know what the heck Bill B was talking about.

I then made an aperature stop at 90mm and 80mm.. Each reduced the yellow halo significantly.. but not all.. I made another aperture stop at 70mm but didn't get a chance to use it as clouds rolled in and haven't left yet... I suspect that the 70mm will get rid of all the color which leads me to beleive that with the baffle in place the
effective aperature is around 70mm.. No Theory just what I see.

The one thing I haven't tried is widening the baffle to 2"5/8 and putting it back in.

The bottom line is this. If you want to take advantage of the full 102 aperature on deepspace and still want to look at planets then take the baffle out and just use aperture stops.

If you are mainly looking at planets and look at deepspace
occasionally leave the baffle in.

One warning... if you attempt any of this then please please please watch out for the grease on the threads of the focuser.. And be real careful when screwing the focuser back in as it seems pretty easy to
crossthread.


Hope this helps..
