  1. Nope we've had shocking skies and seeing here Charl, was lucky to get what I did dodging those clouds. Perhaps early December we may have some luck.
  2. Yes Michael, it was disappointing to see it 3 days later from when I first noticed it on the 15th.
  3. I've had some breaks in the clouds and smoke for some nice solar imaging, conditions still not great but I was happy to get these. In a 3 minute video on the laptop screen some good detail comes through a couple of times a minute briefly for a few seconds. The second image is around 2 minutes as cloud covered the sun at the start of the last minute of the video so I had to stop the recording. Captured in SharpCap with the ZWO ASI 224MC and Celestron UV/IR cut off filter in the Celestron Nexstar 8i SCT with focal extension tubes. Aligned and stacked in AutoStakkert, wavelets in RegiStax, e
  4. I'm chasing some tube rings for a refractor, inside diameter needs to be 105mm or slightly larger by 2 or 3mm as I could use thicker felt. Would need it posted to Western Australia postcode 6210. Thanks. Dave.
  5. 5th November at 4:14am. We still have bush fires around and as far as I'm aware they are controlled burns... This was taken with the Sony a5000, ISO 400, 1/125sec, prime in the Celestron Nexstar C8i SCT, 2 image stitch in Image Composite Editor and final tweak's in PaintDotNet.
  6. October 29th, my best Mare Imbrium, Plato crater, Vallis Alpe using the Celestron Nexstar 8i SCT with focal extension tubes pushing a focal length of around 2500mm with the diagonal. Camera used was the ZWO ASI224MC with a Celestron UV/IR cut off filter. Captured in SharpCap at full resolution with the 1.2mp astro camera, 3977 total frames captured in a 3 minute video, 10% (397 frames) stacked. Aligned and stacked in AutoStakkert3, wavelets in RegiStax6 and edited in PaintDotNet. The image has been cropped, converted to monochrome with some level adjustment and sharpened with high pass sharpen
  7. My best Pythagoras Crater to date using the Celestron Nexstar 8i SCT with focal extension tubes pushing a focal length of around 2500mm with the diagonal. Camera used was the ZWO ASI224MC with a Celestron UV/IR cut off filter. Captured in SharpCap at 1304x976 resolution, 4788 total frames captured in a 3 minute video, 5% (239 frames) stacked. Aligned and stacked in AutoStakkert3, wavelets in RegiStax6 and edited in PaintDotNet. The image has been cropped, converted to monochrome with some level adjustment and sharpened slightly with high pass sharpening. I was quite happy with the result
  8. October 1st. Hand held afocal, Celestron Nexstar 8i SCT with Unbranded 40mm Plossl and Fujifilm 10mp A170 compact digital camera.
  9. The weather has not been kind to us here in the South West of Western Australia and when there has been clear skies, seeing conditions have not been great. But I'm still at it! Here are a handful of lunar images that I've captured this month. October 1st. Hand held afocal, Celestron Nexstar 8i SCT with an Unbranded 40mm Plossl and a Fujifilm 10mp A170 compact digital camera. October 4th (I think). Celestron Nexstar 8i SCT with the ZWO ASI224MC with Celestron UV/IR cut off filter. Captured in SharpCap, aligned and stacked in AutoStakkert3, wavelets in RegiStax
  10. Amazing Freddie. I didn't know that white light could get this sort of detail with granulation. This is something I'll be striving for in future attempts.
  11. Thanks guys. I believe it to be one of my better attempts although conditions are still not great here and I was late getting out there. The sun was probably 50-60 degrees above the horizon and dropping. I don't do as much solar as I would like due to work and the weather hasn't helped either, it's been cruddy for weeks. I'm still not sure how far to take it as far as the granulation goes and feel I've overcooked that second image and was on my way to doing the same with the third image but held back on that one. @Freddie it would be interesting to see the change if you can get out a
  12. I managed to get some solar imaging in this afternoon. Today I used the white light solar film filter not the solar glass filter with better results than my previous attempt. Still battling some wind and passing clouds. Location Mandurah Western Australia. First full disc solar image is a single exposure handheld afocal with the Sony Cybershot 14mp compact digital camera near a 40mm Plossl eyepiece in the C8i SCT, The second and third image is with the ZWO ASI225MC stacked and aligned in AutoStakkert, 112 frames with the third image a full res crop. Wavelets in Registax, final
  13. Captured this afternoon in Mandurah, Western Australia. Taken with the ZWO ASI224MC and the Celestron 8i SCT with focal extension tubes and white light solar film filter. A two minute video was captured with the final image being cropped and having 10%, 112 frames aligned and stacked in Autostakkert 3, wavelets in Registax 6, edited in PaintDotNet.
  14. darn it, the 22's would of been perfect I reckon :/ I didn't look at all the results. I should of searched for 22 or 23mm, oh well.
  15. I bought the M6 25mm hex bolts or what we call over here in Australia Allen key head bolts which seem to be referred to as the same in the UK going by that site. I was only referring to them as hex screw/bolts in the opening post as that's the results I got from ebay's listings and I wasn't sure what other people knew them as from different countries. If I said Allen key, someone would of said hex. As for bolts that you use a spanner on, we just call them bolts, that's it, simple. I know you all knew what I meant, no biggy. I think the 20mm long ones would still be a little short although
  16. Are those correct in that link? They are longer than what I have by a few threads but a bit longer would be better. M6 thread type, 20-25mm length of threaded section seems to be what I need.
  17. Cheers Roger, looking at M6 20mm but no there's mention of the length of the threaded part. atm I'm visually sizing them up by eye to get longer ones than what I have. I have round head screwdriver bolts in there now as they are a little longer but I don't like the look of them. Thanks LB, I can also see the partially threaded ones, I don't think that would be an issue unless it would affect going through that first hole of the dovetail bar. Mine seem firm getting the threaded part though. I'm looking at these but they don't seem to be much longer http://www.ebay.com.au/itm/4pcs-M6-x
  18. Hi all. I'm wondering if anyone can tell me the name for the mounting bolts for a standard dovetail to OTA rings are called. The only reference I've found so far are M3 and M4 hex head screw/bolts and I'm still not sure on these as far as size goes, thread size, width etc. I need two longer hex head screw/bolts for a refractor, has the standard dovetail bar and the ones I have from another dovetail bar and rings are too short. I'm only getting at best one complete turn on the thread. I need them about 20mm long. Dave.
  19. Hi Charl. With your prom images is this still Ha and is there any way to bring out proms with white light solar filters film or glass?
  20. Thanks all. Another video processed tonight, slightly larger image scale. I'm starting to get those extra rings on the disk, just need to tweak collimation and capture settings. Not sure how to go about capture settings though.
  21. I met a couple of fellow amateur astronomers last weekend and had an overnight stay about 2 hours north of Perth Western Australia. Had an great night talking about astronomy, telescopes and imaging. I imaged a couple of planets and a couple of larger DSO's in the middle of nowhere with dark skies. I used my Saxon 8" Mak which I've had for quite a while now and only used it a couple of times for some visual. Collimation was slightly out and I adjusted as best I could. Captured in SharpCap with the ZWO ASI224MC, processed in PIPP, AutoStakkert, Registax and finished in PaintDotNet.
  22. I noticed tonight a lonely Jupe video that I hadn't processed. Captured with the Celeston Neximage 5 Color Solar System Imager in iCap with the Celestron Nexstar 8i SCT with focal extension tubes, focal length about 2500mm. PIPP used to get the better 4000 frames from a 3 minute video with 20% of these stacked in Autostakkert with 1.5x drizzle. Wavelets in RegiStax and finished in PaintDotNet.
  23. It's not often I do afocal on planetary. This was purely a test with two of the cheapest items you could buy from Ebay, an unbranded Moon and Sky Glow filter and a Celestron 10mm Kellner eyepiece. Tested in a Celestron Nexstar 8i SCT and captured with a Sony Cybershot 14mp DSC-W610 compact digital camera, handheld near the eyepiece, ISO 80, exposure -2.0, 8x zoom. Visually looking at Jupiter the eyepiece has light scatter and some ghosting from the bright planet and bright smaller objects but when the Moon and Sky Glow filter is fitted the view becomes better, dropping the brightness of J
  24. I've also just noticed something. My avatar seems to be brighter. Maybe this has been an upgrade to the SGL code somewhere along the way.
  25. I'm glad you did this test Neil. Any tests on facebook? I suspect it to be similar to SGL. From what I remember the older version of the SGL forum didn't have this issue, or was less noticeable.
