  1. That's a great image Graem, processing & colours are spot-on. Martin
  2. Actually it's not that bad at all. OK, the stars are somewhat elongated and there's a focus issue, but the causes of these can probably be fixed quite easily. You don't give much information on the subs, or whether a reducer is in the imaging train. Assuming there's no reducer, then firstly check your polar alignment (PA) - just run a 5 minute sub (luminence is fine) with no guiding, if the stars are nice and round then the PA is OK, if not, then start here with the fixes. If PA is sorted, check out the quality of your guiding since poor guiding over lots of 10 minute subs can also give poor stars. The focus definitely looks a tad out though at the moment, again I'm not sure what focusing method you use, but try racking in or out a few clicks on the focuser and see if the stars tighten up - if the stars are out of focus, then your nice wispy nebulosity will also be out of focus. Finally, if you do have a reducer in the imaging train, double-check the spacing to the CCD since if this is a few mm's out it can also cause a lot of problems. HTH's, Martin
  3. For the last couple of years I've used Pempro software for PA and had spot-on results. It's more expensive than Alignmaster though, but is a much deeper package and offers many other analytical tools including backlash measurements. Before this I did use Alignmaster though for my PA and it worked just fine. As mentioned above it can be tricky choosing two stars that are easily visible, but if you scroll down the list for each then usually there's always a good pairing to be found. It's quick to run, and a second run may well sharpen up the PA even further. For the price, I think it's good value. There's a very nice youtube video from Dion of AstronomyShed showing how to use it. Martin
  4. Dave - that's a cracking good Pelican, very well processed and framed - you're certainly not rusty at all after the gap you've had with your imaging. Martin
  5. Yes that's really nicely executed - if you add OIII now, it'll be a lovely bicolour of blues & golds.
  6. That's a glorious widefield of this region, and nice to see the much over-looked SH2-119 included as well. Processing is spot-on as well, all together an excellent image.
  7. Great image, and all credit to you for going off the beaten path and taking on this tough target, it's come out a treat.
  8. Mike, I know the feeling! When I first started imaging some 5 years ago, I looked at Maxim with considerable trepidation, it all looked so confusing especially with such a vast array of menus and sub menus etc. Today Maxim is one of my best friends, I run everything through it including guiding, plate solving, image capture and automation, calibrations, stacking and alignment. The only area I run separate is focusing which I do via FocusMax. If you can just get to grips with the basics, slowly but surely, the rest will come along and then you'll appreciate just how good Maxim is as a package. You don't list the kit that you are using, so not sure if you are DSLR or CCD based, but PM me if you need help with any specific tasks in Maxim. Martin
  9. Agreed - that's a really excellent image - it's usually packed with pesky satellite trails and is very faint, so you've done very well with this.
  10. Yep, as above a plastic box with lid, placed on it's side so the lid goes on/off at the front. I use this even in my observatory since there's so much moisture & condensation now that it's essential to keep the laptop inside this. I've drilled a hole in the other side (actually bottom of the plastic box) and fed the cables through this, it's now very well insulated from the elements and Teamviewer runs all night long like this. Martin
  11. It's an incredible image Paddy, and all credit to you, especially for the excellent "touch & feel" that you undoubtedly have with processing. The full size version is an absolute joy to view in terms of resolution, clarity, palette - and of course the sheer number of those eye-popping and colourful tiny galaxies everywhere!
  12. I think it's likely that you have significant tilt in your imaging train. I ran your image through CCD Inspector and it showed the tilt on the LHS.
  13. Yes, I'm 'all ears' as well to hear about this normalisation step during stacking to even out the backgrounds of panels for a mosaic. To date I just eyeball the panels next to each other and adjust one or the other very slightly with curves in PS to get a match, but sometimes it plays up. Martin
  14. Thanks for the feedback from everybody, I now have bahtinov grabber reinstalled on my new laptop. Martin
  15. Looking darn good so far Rob - this is going to be a classic once finished. Martin
  16. But the weblink to Bahtinov grabber on the 'Home' page of APT also doesn't work?
  17. I used Bahtinov grabber software years ago, and it was excellent. I'm setting up a new laptop at the moment for my observatory and want to reload this, but the original website for Bahtinov grabber seems to be dead now. This is the link to the site I used before: http://www.njnoordhoek.com/?p=325 If anybody knows of a new/functional link for this software, please let me know. Thanks, Martin
  18. That's a great version of the Pelican - the strength is in the processing, really well handled, nothing is forced. Martin
  19. It may be best t o contact Moravian directly - they have a very good customer service system and have helped me with drivers etc. I'll dig out the email address/contact and send it onto you in a PM.
  20. John, try Alignmaster, I've used this before when I've had trouble with a mobile set-up. There's a nice video on Astronomy Shed as well on how to use it. You just need to stars well apart and it gives you menus with a big list to choose from. The PA is usually very good with this software. http://www.alignmaster.de/ Martin
  21. Yup, that's a great version of the Iris, lots of lovely nebulosity there.
  22. That's a stunning image, superbly processed as well, great job.
  23. Lovely image Barry - the processing is just perfect, not pushed at all, and the result is a very natural delicate outcome - top drawer! Martin
  24. Yes this is a highly effective way of showing this region in all it's glory by merging Ha with LRGB. We don't often see it in this format, but it's worked very well indeed. The full size view especially is incredible and gives a dramatic appreciation of the density of stars in this field. Martin
  25. George - take a look at this thread also, may give you some direction as well
