    Interesting things from microscopic to telescopic.
  1. No worries. If I knew how to send you the original files, you are welcome to play around with them. You've done a good job bringing out more detail with just the JPEG, especially the brown dust. I would like to see what you could do with the original TIFF &/or FIT files. I would get more data but I am extremely flat out this time of year with my job, which really sucks as the weather here is ideal at the moment for imaging. I like the old ED120 too. It's been a great scope for my capabilities. Yes - how did you do this? Dan.
  2. That's right. I remember now..you're using the QSI with Off axis guiding yeah? Can you do a recalibration in Maxim after the flip? I'm not familiar with Maxim as I use PHD. I like PHD as it's easy to use and basic. My SSAG is older than that. Probably around the 2011 I think or older? So hopefully I'm safe. Yes the SSAG is the QHY5 I'm pretty sure. Updates really drive me nuts. Everything requires an update it seems. Probably a way for manufactures to make things obsolete in an attempt to make us upgrade. I would not be happy either.....It's always the way, something crappy happens when you least expect it. Maybe one positive is an opportunity to repro some old data perhaps? Dan.
  3. Thanks Guys, Still not professor quality, probably a bit over sharpened when I look at it again. I was a bit blurry eyed while processing which made me sharpen a bit too much. Using my old skywatcher ED120 (upgraded to moonlite focuser) with 0.85 Focal reducer and QHY9 mono. Using astronomik filters. 6x5min L and 5x1min L and RGB all 3x5min. Was lazy and used 10min dark frames as I forgot to do more darks for 5 min subs. Combined the 5 min subs with 1 min subs as Luminescence frame for the core and a few layer masks. I had to try the reducer to flatten the edges out. The old skywatcher is only a budget scope and the edges are a bit crappy when using the KAF8300 chip as it really shows up the imperfections/limitations of this scope. I think the reducer helps with flattening the edges. Dan
  4. Had an opportunity to try out the T2 adapter for my focal reducer the other night. Not a lot of data, but enough to slap an image together. Dan
  5. Hope you blokes don't jinx me. My SSAG has served me great over the years. What focal length or ratio is you guide scope Ray? Dan.
  6. That's good news. Bloody insects are a curse. I have earwig issues if I leave my scope setup overnight, so after every use I have to pack the scope/camera away. Lucky I have a dust tight sealed box. One of those big plastic boxes that goes on the back of utes or 4WD's. Takes time to pack up and set back up, but better that than breeding earwigs in my scope/camera. Good to hear though. Hope you can get set back up and imaging soon. Dan
  7. Amazing image Greg. 40 min subs? Crazy! Great guiding and patience. Dan.
  8. That's giving the Mrs the universe (or part thereof)! Dan
  9. Well done. All great looking shots. You will have to show me PI one day. Looks like you're getting the hang of it. Dan
  10. That's the stuff. And a very handy website that I'll be adding to my favorites. Thanks Ray. Dan.
  11. Yeah Shane, pretty good. I found these tips for NB processing. No star removal tips but more of colour tips. The overall results can be subjective depending on what you like. Use SII for the red channel, Ha for the green and OII for the blue. Adjust R, G, B channels in the histogram so they all overlap. Duplicate the base layer and open "selective colour" and choose greens. Reduce cyan component to -100% and magenta to -25%. Next select yellows and reduce cyan to -100% and magenta to +25% select cyan and reduce yellow to -100% and click OK. Open "selective colour" again and select cyan and reduce yellow component to -100% and magenta to -25%. Click OK. Magenta may still need to be adjusted if required. Dan
  12. Good to hear Ray. By memory, it sounded complicated at first, but once you get stuck into it, it's not too bad. Easier if I drop a USB stick of some old data in for ya. I'll dig out some post Deep Sky Stacker data tonight. Or I can give you the subs. Dan
  13. Hey Ray (and everyone else too)....The person I saw is J-P Metsavainio. Here's a link to "Tone mapping". Only thing is, he uses PS. I only use PS as it's all I know and have. I do have Nebulosity but I only use that to capture. I am aware PS only does 16 bit, but my images don't warrant the time and money for PI as yet. I may look at PI later on when I get better data. But have a look at this blokes website. He's bloody good. I guess I am particularly interested in his stuff as he has the same camera as me, so something for me to aspire to. Plus it's in PDF so you can print out or save for later reference. I hate YouTube tutorials...I just want to fast forward but can't in fear of missing vital bits, but after watching them I realise what a waste of time and wish I did fast forward! https://dl.dropboxusercontent.com/u/24702393/Tone Mapping_v2.pdf or if that link doesn't work https://astroanarchy.blogspot.com.au/2014/04/tone-mapping-v20-my-lecture-at-neaic.html and click on the picture Interesting website if nothing else. I hope this helps. Dan.
  14. Nice one Shane. Colour and detail look good. Definitely a keeper. Dan.
  15. Nice one Ray. Do you do star removal when doing narrowband? I came across a website somewhere once and it was quite interesting how he processed narrowband. I tried it out and seemed to workout really well. I saved his steps. Only problem, it's on my old computer somewhere. But your results look similar. Good one. Dan.
