  1. While setting up my latest attempt to 'equatorialise' my Nexstar SLT 127 alt-az mount the other evening, I realised that the Moon was making a close approach to Aldebaran. Couldn't resist having a quick snap. My Heath Robinson wedge survived the evening and will hopefully produce some useable deep space images in due course... Canon EOS-M prime focus on Celestron 127 MAK.
  2. Being a townie, the opportunities for seeing Mercury are few and far between for me. So a short holiday in Cornwall, at Porth near Newquay, coinciding with an easterly elongation of Mercury had me praying for a clear evening and a low westerly horizon. Sunday 17th April provided both. Canon EOS-M with 18 - 55mm kit lens, 4s at f/4.5, ISO400, cropped from a view taken at 18mm focal length.
  3. The 98% gibbous moon was passing Jupiter during the night of 23rd / 24th Feb. This was taken with a Canon FD 70 - 210mm FD lens (set at 210mm) on a Canon EOS-M. Thanks for looking
  4. Hi Davide - good image! I too have a Celestron SLT127 and I'm constantly impressed by it. How did you go about making your homemade wedge for the AltAz mount?
  5. I think that's Alkaid near the comet, not Alioth? Well done capturing the ion tail!
  6. Yes, when I found out I could achieve infinity focus on the EOS-M with the FD lenses I kicked myself for selling most of my old Canon kit for a song a few years ago!
  7. Last month I picked up a 'for spares or repair' Canon FD 135mm f/3.5 lens from fleabay for £10. It was advertised as suffering from slight fungus, which proved to be minimal and some terrestrial test shots gave encouragingly sharp results. Then came the wait for a clear night, which finally occurred 8th - 9th November. I don't have an EQ mount of any kind, so had to put my EOS-M with my cheapo lens onto my Celestron 127SLT Alt-Az GoTo. I took sets of 10 exposures each of 30 seconds at ISO 200 and ISO 800, ran them through DSS and then used Photoshop to tweak levels and combine the 2 resultant stacked images. I'm quite pleased with the result, although I haven't quite got the field rotation error nailed down.
  8. The clouds parted and Jupiter did not twinkle this evening! Celestron 127SLT, SPC900 and 2.0X Barlow. Registax 5 and Photoshop/
  9. Image as above after more work with Registax 5.1 wavelets, rotation and then a little photoshop for colour balance and so on.
  10. Finally managed to stay awake for Jupiter to appear above next door's roof and beyond... Celestron NexStar 127 MAK, SPC900 and 2X Barlow
  11. Put together 3 avi's and posted result in a new thread - big improvement! Thanks for the advice, James!
  12. I joined up 3 avi's captured in succession and now with 1021 frames from 2100 in Registax it improves things - so now able to get a bigger image scale.
  13. Thanks for your suggestion, James. I missed the opportunity Saturday night and Sunday has started very unpromisingly . When I get some time I'm going to try using frames from 3 avi's taken in fairly quick succession on Thursday. I'll report back on how it goes.
  14. Celestron 127 SLT Mak with SPC900 and a X2 Barlow. Seeing variable between poor and average as well as thin high cloud drifting across reduced 1000 frames taken to about 220 used. Registax 6 and Photoshop to finish. Fingers crossed for a couple of nights with good seeing before Mars gets too small!
  15. Thanks - I admit I was rather pleased considering the wind was still blowing quite strongly. When I set up the exposure in WxAstrocapture, I could see that the moons were being recorded, although faintly - my main concern obviously being not to overexpose Jupiter. After processing through Registax and Photoshop as normal the moons were not visible. I ran the avi file through VirtualDub with increased contrast / brightness settings to show the moons on the output file (with a bleached-out Jupiter). Used Registax on this avi to produce an image which I then put into Photoshop and erased Jupiter. Copied this image and pasted it into a 'difference' layer on top of the good Jupiter image. There was obviously a bit of tinkering about on the way to get it looking more or less right, but that's pretty much it.
  16. Best I've seen this apparition. Lovely image.
  17. A clear night after the storms, so had a first go of the year at Jupiter before it disappears for a while. 19:30 U.T. 03 Jan 2012 Mak 127 SLT, SPC900 Jup_20120103_1930_30c_moons.bmp
  18. Hi all Same AVI as earlier post after a bit more work in Photoshop.
  19. Reasonable seeing here for night of 15th / 16th October. Spent a few happy hours with Jupiter and my SPC900 / Celestron 127 SLT combo. Here's one of the first results after Registax and a little Photoshop:
  20. Thanks Clayton. I think there's more in there if I can get spot-on focus and really steady seeing. But the clouds seem to be back for the foreseeable future...
  21. Finally got some breaks in the cloud and adequate seeing last week. This gave me a chance to try my new baby - Celestron 127 SLT Maksutov. Jupiter with 3 moons, early hours on 15th September 2011. SPC900, 2 avi's one for Jupiter detail, the other overexposed to get the satellites. Registax 5 then images combined in Photoshop. Capture 15_09_2011 01_16_00moons.tif
  22. I agree the orange /yellow looks odd, but that's what the SPC900 produced on the night. However, I've pulled down the saturation in Photoshop and it looks much more natural. I made 9 avi files varying from about 2 to 5 minutes, then used VirtualDub without any filtering to split some of the longer ones into smaller chunks before stacking. Main reason for doing this was that the longer captures had drifting of the image due to imperfect RA tracking speed and polar alignment..
  23. Found time this long weekend to put together a Moon mosaic from avi's taken on 23rd March 2011. First time I actually achieved 100% coverage .Celestron 130EQ MD and SPC900. Individual images stacked in Registax 5, then stitched with Microsoft ICE and tweaked with Photoshop.
  24. Not really - just selected those where I'd managed to get the motor drive rate about right. Funnily enough, the next time I tried for some images, the results were nowhere near as 'good' - transparency was not so good, later at night (= lower in the sky) and telescope dewing up fast. Hopefully we'll get some proper weather down here in southern England soon so I can try again!
