  1. Am going to have to go through all these things. I think I shall initially make sure everything is tight enough which is something I should have done after a summer lay off! Will certainly consider backlash and periodic error. Thanks again Annie
  2. That makes sense Michael, for a while I had better results doing a two star alignment with stars near my target as like you it's normally one target a night. Will try your suggestion though. In the meantime I now have star trailing on two or three of my images - to me that suggests something is moving though not sure how to start diagnosing it!! Thanks for the suggestion Michael - much appreciated. Annie
  3. I've started to have alignment problems with my NEQ6 and synscan. Am aware that there could be a number of causes. I don't think it's an optical problem but some kind of mechanical problem. Until now I have always done a three star alignment and wonder if it's significant that it is the third alignment star that is now never anywhere to be seen? I have re polar aligned using polemaster as usual and done a factory reset so am looking for the next issue to consider. So frustrating on clear nights to take over an hour to align and find my target!! Annie
  4. The MGEN 11 guider has been superseded by the MGEN 111, I have been using the MGEN 11 for a number of years with a lot of success . Am I right in assuming I am too late to buy another new MGEN 11? Annie
  5. I should have said thanks for the info though - that's useful to know Lee.
  6. Thanks Lee - just solved the problem. Had my dunces cap on and simply named my project without specifying a location!!! Process template now saved as a template. Annie
  7. I want to create a template of the processes I will normally use in Pixinsight and assumed I would just open them onto my desk top and then save them as a project but when I do this am getting an error message: Win32 error - access denied. Am I doing something wrong? Thanks Annie
  8. If you want to spend some money try Adam Block's Pixinsight tutorials - he does two: Fundamentals and Horizons. Have got the first one and think it exceptionally good and comprehensive. A lot of hours of video tuition which means you can run Pixinsight alongside and follow what he is doing. All in all very well presented and very clear explanations. Annie
  9. I use Lacerta MGEN as a stand alone guider so not sure Sharpcap Pro would be appropriate? Am not convinced that polar alignment is the cause of the poor alignment as polemaster has always seemed a pretty good tool. Have always tried to avoid too much computer involvement as I fear if I move in that direction I shall be moving beyond my level of competence! However I suppose nothing ventured nothing gained!! Annie
  10. ok - will have a look at that. Thanks. Annie
  11. At the end of last season I was beginning to despair about alignment issues and with the prospect of a few clear nights thought I would try and rectify the issue but am far from clear about the cause. I image with Takahashi 106, Atik 460 on NEQ6 which I control using the handset. I polar align using polemaster and as far as I can tell it's accurate. I three star align though usually have to search for stars as they are often low and left in my capture software - Artemis. Any target was usually very low. I was thinking about doing a factory reset? I also wonder if I slew to an alignment star but instead of using the handset to centre it what would happen if I centre it manually using the the altitude and azimuth adjustments? Might that redress the issue? Annie
  12. That's a piece of work to be very proud of Carole - love the processing. Annie
  13. Sorry Ken!! Have had a look at all the suggestions and have to say the Feather touch is very tempting and as am now in my 70's - what the hell!! Am now looking at motors - any suggestions in that direction? Annie
  14. Am going to have a look at the Revelation. If by any chance I don't find it satisfactory I can always go for the expensive option. Thanks for the suggestions guys - much appreciated Annie
  15. Am planning to buy a C9.25 specifically for lunar/planetary imaging and will be using it on my HEQ5 with a ZWOASI74. I want to add some kind of focuser to this set up but not sure what to consider so would appreciate some advice. Although my DIY skills have improved since I started deep sky imaging they're not great so looking for something fairly straightforward. Budget is not a huge issue. (but not limitless!!) Annie
  16. Have only just got APP and found this on their site : Complete LRGB Tutorial of NGC292, The Small Magellanic Cloud. Annie
  17. I usually stack in DSS and process in photoshop but recently bought Registar and used it for the first time yesterday as I have some Ha, LRGB subs (taken over several nights) of M101 which I would like to align and combine. All the LRGB subs are 300sec, 1x1 binning and imaged through Baader 7nm filters. The Ha subs are 600secs, binning 1x1 using Chroma 3nm filter. Am happy with the process of aligning and cropping/padding each channel in Registar but am confused about combining each channel and then aligning the Ha and Luminance with the RGB file. If I use DSS to stack each channel a 32 bit tif file is produced which Registar will not open. I get the following message ' Please ensure the file has not been compressed using a proprietary compression scheme' ? Thanks Annie
  18. Super image and nicely presented. Annie
  19. Am hoping the forecast is right for tonight so am intending to use my 3nm Ha filter for the first time as part of my luminance. If I was using a 7nm filter I would collect 7/8 x600secs. Should I collect more with my 3nm? Probably a naive question!! Annie
  20. Doug German does an excellent tutorial on Multi-session stacking in DSS. Annie
  21. I can't see the image either! Annie
  22. I am replacing two Baader 7nm filters with two Chroma 3nm narrowband filters, 36mm unmounted into an Atik EFW2. Have replaced one but am not sure I've done it correctly so before I fit the second one would appreciate some help. It's a different design from the Baader - deeper and I haven't managed to get it to fit as flush as the Baader ones? The Baader filters are mounted on a rubber ring and screws with little white spacers are used to secure the filters so they are flush. I've assumed I should do the same with the Chroma filters though the rubber ring is very fiddly to fit - I've just dropped it in until it looked ok and then dropped (gently!!) the filter on top ? It's all a bit nerve racking thinking about how much I've paid for the filters!! Annie
  23. I've never looked back since starting to use Polemaster - brilliant bit of software - easy to use, just follow the directions on screen. Annie
  24. Thanks Joe and thanks Kinch. Have looked at the link and note the need for precise back focus. Haven't yet looked to see how my imaging will be affected but will do and as you say it could give me a nice option. Annie
