After a couple of telephone conversation with a very helpful Lee Andrews of Andrews Communications http://www.andrewscom.com.au/site-section-10.htm, I asked the question about upgrading the standard 'series 500' EPs, for GS items, which he did for me, as I was prepared to pay the difference.
The reason for this thread is that Mr Andrews mentioned that he had vague, negative feedback regarding the series 500s, but nothing concrete.
Very descriptive and informative BD, nothing I can add to that.
Lee should put one of his scopes together, grab a couple of 500s and a few decent eps and try them out. Then he might wake up and see the light.
Thats a major problem with dealing with a non astronomical vendor.
I got proper GSO's with my dob.. and made sure they were the proper GSO's when i ordered them. Lee didn't charge me anything extra for the GSO over the series 500. He gave me the spiel about how they come from the same factory yada yada but i said that i'd rather the proper ones... and he was sweet with that.
I havent spent much time at all looking through them to give a critical appraisel, simply because they were so bad compared to the other plossls I had on hand at the time. What I recall mostly is that the contrast and light scatter was woeful.
The four symmetrical spikes are due to the spider; the fifth longer spike rotates with the eyepiece, and disappears when I replace the S-500 with a GS 25mm PL or a TV 15mm PL.
Question:
How do you tell if you have Series 500 Possols from Andrews (Apart from the "terrible" views) are they labelled Series 500 ?
Mine are simply labelled "PLOSSL __MM FULLY COATED"
Are these series 500 or GS Plossl's ?

Mine have "Andrews plossl x mm" engraved on the side in silver.
Ian. sorry for the quality of the close-up. This camera isn't good at the close stuff but this is how s500's are marked.
Are you sure your camera is a Kodak?? My old Kodak "Millenium" has a "tulip" button for close-ups, but it takes something like 20 minutes to get a roll of film's worth of photos onto the puter over its serial link ($40 ebay job).
Thanks Guys
That makes it really clear ... I have the GSO Plossl's thankfully
I will have to make sure I tell those who I recommend to get the Andrew's Dob (and I do that often) that they insist on the GSO Plossl's.
I have been happy with my GSO plossl's (except the 4 & 6mm which are naturally, pretty useless)
Geoff, If I remember correctly, Lee said the 'Andrews' marked ones he gets labelled at Synta for him. The s500's get sent from GS factory to him with the GS scopes as an included factory accessory.
