PHD2 - It's like melted butter on toast

Recommended Posts

PHD2 has been popping up in various places on this forum, with many if,buts and maybe's.

So last night while I was waiting for the clouds to clear, I downloaded and installed it.

(I was a bit annoyed at the additional stuff that you needed to install, but hey, if it works it works.)

So plugged everything in and started it up. Some of my WOW moments:

- The equipment profiles that seem to be pre-tuned. (So plug and play!)

- Auto tuning of your camera dialogue and the new darks works great, stars where bright and the background black ... out the box.

- The new / updated graphing and the star profiles are very cool. (Still need to learn what all the new stuff means!)

- Seems more stable and less resource intensive / laggy.

Although when I woke up this morning, it had frozen and so had EQMOD. Was this because it got confused when the clouds rolled in?

(The clouds rolled in at about 2am, so managed 3hrs data, all tight 5 min subs at 900 FL, with a 600D and a Finderguider 200FL.)

Looking back at last night I have some question for the veterans.

99% of my nudges kept me within 0.5 target on the star profile. I had 1 in a hundred that pushed out, but always below 1.

My Dec was buttery smooth, almost no movement at all a flat line, sometimes just below the line and other times just above.

My RA was more hacksaw blade, with higher peaks (EQMOD) than what I got with PHD1.

How should I tame the yo-yo effect so that it if a flatter line? (EQMOD is set to 0.5 RA and 0.9 DEC, min pulse is smallest at 20)

(Avg size RA Oscillation between was 0.2 and 0.3, but some times up at 0.5)

Anyway just a big thumbs up to the DEVs and really everybody should give a go, it is super cool.

      Hello all,
      So I routinely have issues with guiding. Last night, I was getting some solid sub exposures of 5 minutes on the Flaming Star Nebula. When it got to about 15-20minutes of the meridian, I began getting trails on my stars. Then after the flip, I was still getting trails despite PHD reporting all's well.  I moved over to the Horsehead Nebula and tried 5 minutes there, and it behaved itself. Then I tested it on the Jellyfish Nebula and it also behaved (just about - minor trails). But it just did not want to dig it with the Flaming Star Nebula, which was practically near the zenith (about 2:30am 30/11/19).
      I tried recalibrating PHD (I use Pulseguide so the scope knew where it was). I then also recalibrated PHD at Alnitak so it was near the celestial equator (as the PHD best practices recommend). I even checked my Polar Alignment (done with a Polemaster), which was fine. I couldn't find anything wrong. 
      The guide scope was slightly off alignment with the main OTA, but that wasn't making any differences before the Meridian. 
       
      I did find the helical focuser of the Starwave 50mm guide scope I was using to have some movement in it again when I manipulated the guide camera. So that's something I need to look into. But before I start throwing money at this issue, I see the terms "flexure" and "differential flexure" coming up. Can anyone shed light on what this means please?
      I tried manipulating the OTA in its tube rings, that didn't yield any movement either. The piggyback scope is secure, the g/scope is secure in its rings as well, there's no movement in the OTA focus rack and the cameras are secure in their tubes. 
      I do have my guide rings quite far back on the body of the telescope to assist with fitting the guide scope piggyback. 
      Video of g/scope play: 
       

      Flaming Star Nebula. 5 minute sub, post Meridian Flip, about 2:50am (30/11/19). Note the plate solve compass in the top left. Drift appears to be in S/W direction.

      Position of tube rings (they're now at the focus end).
      I think I am leaning towards needing to move my tube rings (once I remember to get the tools from work). 
       
       
      Equipment:
      (brand new) Skywatcher EQ6-R Pro, SW Evostar Pro 80ED, Altair 0.8x R/F, Canon 600D, Altair Starwave 50mm Guide Scope, Altair AR130 Mono Guide Cam.

      Hi - I've not posted here before as only just launched into this hobby, although I've always been massively interested in astronomy.
      I had first light on my rig last night, which is:
      Esprit 100, HEQ 5 Pro, ZWO EAF, ZWO mini filter wheel, skywatcher 50ED guidscope with ASI120, ZWO1600mm Pro, Lynx dew controller w 2 astro zap tapes
      A big endeavour to get that lot working from zero experience, but I love a challenge and have really enjoyed the computer side (I'm a grade A nerd)...
       
      So - what went well... I got the guide scope in focus (was stressing about this), and also the main scope. Even more awesomely, the autofocus routine in SGP is working perfectly Filter wheel also working perfectly and I'm getting lovely smooth pics from the main camera (I've already done the flats and darks while I was waiting for clouds to clear). Final good thing (well, good-ish), is that I got the platesolving working eventually, and was able to get the scope to align from Park to the Soul Nebula and centre fine. For some reason the "number of attempts" in my SGP profile hadn't applied, so it was giving up after 1 go, but I got it working in the end.
       
      So the bad...
      I couldn't take any data because every time it finished the platesolving and started PHD2, PHD2 would start the calibration process and then halfway through, the sidereel tracking on the EQMOD panel would turn off. Obviously, that would lead to a "lost the star" error. Is there some reason why sidereel tracking would turn off like that? I'm generally a bit confused as to whether I should be controlling the telescope from SGP (i.e. unpark) or using the park and unpark + tracking button on the EQMOD panel. Both PHD 2 and SGP are setup to use EQMOD ASCOM HEQ5/6?
      So at the moment I can't do anything, because there's no way of guiding without it turning tracking off
       
      Also I was cold. Very Very Cold.

      Hi to everyone, I used to do some astrophotography in the past with a Celestron AVX and DSLR but after few month had to give up for several reasons, including light pollution (I'm living in zone 3 east London), and also working shifts. Now I want to start again, and this time more serious. I've been searching around for a couple of months to choose all the gear and I'm quite happy with the list so far although it's a bit over the price I planned at first.
       I will get an William optics Z73 with his 50mm guide scope, a flattener/reducer 0.8, light pollution filter IDAS D2 and as camera I will use a Canon 600D modded and I will buy a ZWO 183MC Pro, after so much research, I'm very happy with the scale and framing I will get with this combo, but I'm starting to get confused with the mount.
      My first idea was to go for an HEQ5 Pro, as my previous experience with the AVX has been awful, then I realized that the FLO, sells that mount with belt modification and also some cleaning and tuning if required, I heard that it's a big improvement over the stock one and the price it's ok, but another important factor for me it's portability. Unfortunately, my garden doesn't allow me to do much so I will need to carry around on trolley, for a km walk, I'm a strong person and been doing plenty of time with the AVX, so my confusion came recently when the iOptron mounts entered my radar. I start comparing the heq5 pro with belt, with the iOptron cem25EC and the CEM40 without encoders, and I'm so unsure of which to buy, the cem25 seem to be the equivalent of heq5 at least speaking of payload, but in some threads I read people saying it's a bit fragile so kind of remove it from the equation although the weight it's interesting for my situation, then the cem40, seem to be quite similar on weight to the heq5 but with higher payload and that's interesting too as I will buy a C11 at some point.
      Now it will all come down to the accuracy of tracking I guess, how the heq5 and cem40 would compare on tracking and guiding? If the cem40 it's better, I would probably go with that since it holds more and would last longer as I don't plan to get anything bigger than a C11, but if the skywatcher it's better, I could decide to go for that, and when I move to a place with better garden then get a second mount with higher payload.
      Apologise for the long post and my english.
      Kind Regards,
      Giovanni.

      Ok, so this is a really annoying bug / problem that I have with my setup:
      From time to time, in non regular intervals the image my guiding cam (ZWO ASI120) send seems to get flipped / mirrored or looks like it's from a completely different patch of sky.
      When I'm paying attention to the guide images I can clearly see that the image seems to be flipped in some way.
      It only happens for 1 frame PHD send a warning ( No star found / Star lost Mass changed) and after that everything is fine again. My gear is all connected to a single USB3 Hub which then runs via powered USB3 cable to my Pc.
      I'm not binning and have the noise reduction off (though PHD might got hickups while processing) but it still happens. Sometimes there are minutes between two events sometimes it happens 5 times in a row.
      It also seems like it's only happening during guiding, I haven't seen it happen during calibration yet...
       
      I'm completely clueless what's happening or how to get rid of it, any help / idea is greatly appreciated.
