Anthony, You are very wellcome. The comet just crossed perihelion in september, and as you mention is moving very slowly. Its magnitude will slowly decrease from now (barring any surprises), and has

PS. According to Heavens-Above, perihelion was Sept 15/2008 which suggests that it is now moving away from the sun. weeks?

Josep, Thanks for the heads-up surrounding this bright comet. I just took a quick look at the ephemeris and it seems to be a slow mover, thus allowing for extended exposures. Do you have any

Dear all, I am an amateur astronomer in Tiana, a small village near Barcelona, Spain. Having acquired a second-hand AP900 in the last year, I have come to appreciate how precise and easy to use this

I finally got the chance to adjust the worm mesh last night and am pleased to report that tracking was perfect all night. In fact, I think my peak-to-peak PE is lower than before (if I ignore the

Hi Dean, Sorry, I typed it wrong. You have to CHECK the box that says "Disable RA/Dec, Alt/Az". If it still scrolls too fast you can disconnect from the mount and scroll up to examine the

Hello, I'm using a Mach1 after upgrading from a Losmandy G11. The Mach1 produces nearly perfect tracking with an average guide correction of less than 1 arc second in both directions most of the time

Thanks for the suggestions Rolando. I didn't get a chance to do any testing with the mount tonight, but I did confirm that I have a fair amount of backlash in RA that is the likely culprit. Being new

ok, I will look at the log and see what it is doing. It does only happen when I click on the button to move it. The initialie on the conection tab does fix it and put it back the way it

The fact the mount does not know/care where it is mechanically makes perfect sense. I was thinking it might be a balance issue for that part of the sky. But when the electric voltage was repaired,

Hi Dean, First, there is no 64x slew rate, so I assume you mean button rate? Second, changing the Button Rate in PulseGuide's Guide/Slew tab does not actually send any commands to the mount so the

Tho, I had this happen to mine the first couple nights at the Chiefland star party, but only when I was imaging objects in the low south. Only happened for 2 nights, and again only in the south. It

I think there is an issue with the current version 1.37 so I was wondering if others had the same issus. If I change the slew rate from 600 to 64 so I can move the scope around, my guide rate gets

GTO gurus: I just noticed a problem with my Mach1 a few nights ago where the mount seems to "jump" in RA by about 1 arcminute within 5 seconds or so. I was doing a PEMPro run with PEC off, and after

Richard, The IOGEAR GBS301 is the adapter that some of us use. Last summer, I paid about $60, plus $10 shiping on-line for mine from a place called PROVANTAGE.COM <http://provantage.com/> No

writes: Yes, you could have had slight change in focus due to power supply problems, which can cause image jumps. There is another possibility. I was just guiding a 20 minute exposure and toward

writes: The RA axis does not know where the Dec axis is pointed, so it makes no sense that it did something in RA with the scope pointed low in the south. Think about this for a minute. I think
