  1. Hi Folks I am trying to get to grips with the wonders of SGPro and I would appreciate some feedback that clarifies what the manual rotate settings mean. I am running a TSAPO60 scope and have to be careful slewing as the filter wheel gets very near to the mount and leaves not a lot of adjustment on the scope rotator to turn it to the required position. I am trying to set up for a mosaic and want to be able to get back to the same camera angle if I take further subs after the camera position has been disturbed. I have read the SGPro help files and checked on the forum but can't get it clear in my head what the rotate angle actually mean in practical terms. Do they relate to the angle of the camera when in the park position or the angle of the camera when fixed on a target, what changes when you put different values into the SGPro control panel. Any clarification, in the simplest terms possible, would be appreciated. Note: I am only using the manual rotate facility. Thanks
  2. Thanks Olly. Watched Sara's video amazing and it looks so simple. Unbelievable.
  3. Thanks for feedback folks, plenty of things to think about, may give them a try. Hadn't thought about ICE.
  4. Managed to complete a 6 part mosaic of the N America and pelican Nebulae. A problem that I couldn't resolve and would welcome feedback on is how to bring all the parts into line. The mosaic attached has a section (top left) that using Pixinsight I couldn't get to blend in with the rest. It stood out from the start. Probably should have thrown the subs for this section away and took some more, but they didn't look too bad individually. I did use David Ault's DNA Linear Fit. Each section of the mosaic were done at different sessions which probably resulted in the differences. I have read since that it is better to take images of each mosaic section in the same session and then repeat this at subsequent sessions rather 1 section in at a time? Unfortunately the uploaded png image does not represent the xisf image of Pixinsight but it shows how the sections do not quite blend in with each other Views welcome
  5. I have the 0.79X reducer/corrector this should sort some of the elongation out??
  6. Update: Spent about 3 hours last night and this morning. Result: not there yet. Although the focus is close the stars still have some elongation in the corners. A painful process in the dark and only having to consistently adjust the spacers a small amount. Hopefully some clear spells tonight for more of the same. Despite being difficult, I appreciate that it has to be got right, or somewhere near.
  7. Many thanks to you both
  8. Me again. I just had a further thought. Building on the information provided if I want to get my spacing on my TS60/ASI1600 combination could I use the same star icon to measure the HFR value for the whole image and watch it vary while I change the variable spacer that I have in the image train?? With the 0.79X reducer, I need camera/filter wheel and spacers to total 70mm. I'm thinking that as I vary the space the HFR will come down as I get nearer and nearer to the optimum value with my set up. I realise that I could use CCD Inspector or CCDCalc - will SGPro do the job for me?
  9. Great news, won't be straining my eyes in the dark tonight looking for small changes in the image. Thanks for your inputs, very helpful
  10. Extremely helpful guys, so what you are saying is that every time I manually move the focuser I can take a quick image and click the star icon to see whether I have improved or worsened the focus??
  11. Simple question. When focusing using SGPro is there a way of getting a FWHM output from each image as the focuser is manually adjusted, rather than rely on eyeballing the image? Thanks
  12. Just by way of an update, having failed to get Platesolve2 to work with SGP I downloaded the Astrometry files and data and tried this as the alternative. Alas, this didn't work either. Eventually Andy Galasso came on the scene and via Teamviewer took control of my laptop and after some time, he found that my laptop had found a bug in the Astrometry software. He cleared it up and issued and update of the software. Astrometry.net now plate solves. Very many thanks to Andy, wonderful. However, on the next occasion of running SGPro, Platesolve2 now works as well. No idea why this is the case but it is sorted. I am still having trouble in completing a sequence in SGPro, it starts, plate solves, auto focuses, PHD guides, takes a couple of images and then seems to go into sleep mode between further images. Log files are in the hands of the SGPro experts and I am hoping for further advice.
  13. Makes no difference
  14. Thanks for taking time to explain, it is becoming clearer. Had another play around and now clear how to open an existing equipment profile make changes and save it as an alternative equipment profile. However, changes made to Platesolve2 settings do not get saved. Any other changes made to camera, focus, filters etc etc get saved to the alternative equipment profile when it is saved. Presumably changes made to Platesolve2 settings should be saved? It means that I can't seem to get the APM catalogue as the default. This may be the reason that I am having so much trouble getting SGPro platesolving to work? Anyone else have this problem. Both catalogues APM and UCAC3 are configured with Status OK
  15. What I can't understand is if I open an existing Equipment Profile Manager (of which I have 1) and make a change to it and save it. I would have thought that that Profile Manager if opened with a new sequence would reflect that profile change. From what I can see it doesn't. The plate solve catalogue always resets to UCAC3.
