  1. Hi all, I'm using SGP Pro and trying to crack plate solving and meridian flips. The mount tries to flip but then can't plate solve back to where it needs to be. I think I've tracked the problem to EQMOD reaching its Meridian Limit. Any idea how to fix this? I've a general idea that I'll need to change the limits in EQMOD, but I'm nervous about this for fear of causing the telescope and camera to crash into the mount legs... Thanks in advance! - Lee
  2. Hi Guys, I have an old C8-N with drives and a handset with an ST4 port. I'm using an Arduino to do small jobs around my setup like exposure control, electronic focusing, guiding and small GOTOs through the handset (large ones take too long). The first three work nicely, by my GOTO is all over the place and I've just realised that whether I'm looking toward the Eastern horizon or the Western one must mean that I need to invert my Dec movements. Is this the case? Is this the only effect of the meridian flip? The RA axis keeps on chugging (and I don't mean collecting for charity) in the same old direction, but Dec needs be inverted. Is there a proper name for these two modes, like "Western mode" and "Eastern mode", or before and after midnight? What else should I look out for? Thanks Steve.
  3. Good evening chaps (and chappettes), the clouds have rolled in so I thought i'd use my time wisely. I'm currently running a 200PDS on a G11, Gemini 1L4, with C2A as my planetarium and PHD2 as it's awesome. All is well, my alignment is great, and i manage good 5min subs from my dslr. 10mins works too if I bother to drift align (mod 1100d). However, I have an issue. I can't get my head around the meridian flip. If I nip outside at an opportune time and ask C2A to do it for me, then it asks for all sorts of parameters that i don't know. Do I just make them up? I've upped the slew speed to 1500 in the losmandy driver, as i've put hi torque motors on my G11 and it's great. Still Gem1, L4, but since i use a PC i don't miss Gem2. Do I put similar numbers into C2A, and if so, what is the centering and guide speed?? I've also bought SGP, but I am reticent to waste a valuable clear night playing with it, when I could be imaging... I'm sure we've all been in this situation! Same reason I haven't put the 120ED with moonlite motor focuser on the mount yet. Actually, that isn't true... That one isn't on there as the wife might see it and realise I've been shopping again! Please someone tell me SGP is worth learning. Currently it looks alien to me.... But really... Do i have to bite the bullet and embrace SGP, and if so, can someone point me to a decent newbie tutorial? or am I missing something mega obvious in C2A... thanks, as ever. Jim
