  1. Yeah looking at some other images on here I can see they're both over saturated.
  2. Brought my old C9.25 out of storage. Really struggling with collimation and sharp focus. Used some old webcams (technology has moved on and I'm considering a ZWO upgrade..) Celestron Neximage 5 / DFK 72AUC02 / Aptina MT9P031 CMOS Celestron Neximage 1 / SPC900NC / Sony ICX098QB CCD Not happy with the images. I need to sort out my scope.
  3. I've just updated all my drivers and software from the Imaging Source site (https://www.theimagingsource.com/products/industrial-cameras/usb-2.0-color/dfk72auc02/) Interesting to see the last driver update is only a couple weeks old! (generic driver for all their products?) The IC Cap software is also much newer than what I was using back in early 2013. SharpCap I see has evolved substantially in the last 7 years. There's now a Pro version I see! Also looks promising that it seems to directly support the Imaging Source/Neximage 5, however I can't find a BINNING option? I remember vaguely getting better results enabling binning in the IC Cap software. Registax seems to have stalled at some point in the past. Is this still the stacking software of choice or have things moved on? Finally I found the Hot Pixel took on the Imaging Source site, but it detected thousands of hot pixels and I thought better of enabling that setting (I think it turns off those pixels?), so left that alone.
  4. I took this with the Neximage 5 over 7 years ago. I've been out the hobby a long time and just searching for the camera to see if it was still relevant. Found your recent post. When I bought the camera it was new out and very impressive. Amazingly Celestron still sell it today, and at a higher price! Camera sensors have evolved significantly in recent years (I'm trying to remember the camera phone model I had back in 2013!) so I'm surprised to see this camera is still being sold. However what I can say is that the lens (your telescope) has always been the main limiting factor, but I'm looking forward to see the improvements in software and tech that has taken place over the last 7 years..
  5. 7 years. Where did that go! I've just dug all my old kit out and trying to remember how it all works. I'm surprised to see the Neximage 5 is still being sold by Celestron (at an increased price!). I would have expected sensor technology to have moved on in that time, it's come along leaps and bounds in the mobile phone world. Anyway I'm back after my interlude.
  6. Sorry I haven't read the whole thread, but my initial thoughts are that you're not pushing the limits of the camera. All of these images are limited by your scope and I don't think the loss in quality using higher compression at higher frame rates is going to be noticeable. I think we would need someone with a large SCT to do these tests to see a clear loss in quality and detail from the higher fps.
  7. The big SCT's are usually the favoured choice of planetary imagers. The C-9.25 is probably the best value sweet spot, but the C-14 is obviously the daddy if you can afford it. If you're on a tight budget then the little MAK127 (sold in many brand names) is very good.
  8. Great image! - might be worth investigating 'MetaGuide' for collimation.
  9. From an email I sent.. thought there might be something useful. ------------------- Sorry for the delayed reply. I'll tell you what I've discovered so far. Normally I use sharpcap, however the binning mode didn't seem to work, so I have been using icap so far. The first thing I needed to change was the white balance values. I adjusted to get the gaps between the bands to look whiteish. Unselect Auto whiteBalance and start with values like: R=79, G=47, B=68. I left colour enhancement turned on. I use gain somewhere around 40-50, and then adjust the exposure to get Jupiter looking well exposed. (something like 1/34 - 1/15) I've been using Format Avi, and DV Video Encoder, however I haven't experimented with the compression tyres yet. Let me know what works best for you. Resolution I've been using either 640x480 without a barlow, or with a 3x barlow using 640x480 with 4x binning. The latter giving best results. I haven't been able to use the barlow without the binning and higher resolutions. I can't get a good enough image. I suspect the higher resolutions will work well for lunar imaging though! Let me know how you get on and what settings have worked best for you! Further regarding compression settings.. If you goto Record Video File -> Settings -> Video Compressor You can select uncompressed and then RGB32. That's probably going to produce the best image, but large file sizes. However I haven't experimented.
  10. Great images from the little scope. The Mak has always produced great images for it's size, and I think you've raised it's profile even more.
  11. There's one now going for £100 inc P&P http://www.ebay.co.uk/itm/Philips-SPC900NC-Webcam-astronomy-astrophotograp-hy-CCD-IR-filter-/170977691141?_trksid=p2047675.m1850&_trkparms=aid%3D222002%26algo%3DSIC.FIT%26ao%3D1%26asc%3D11%26meid%3D5015211799395099868%26pid%3D100011%26prg%3D1005%26rk%3D2%26sd%3D221177187574%26
  12. What sensor does the new Orion StarShoot Solar System Color Imager IV use? Possibly it's the same sensor used in the ASI120MC? (can anyone confirm that?) It's only £80 new, so you would be bonkers to spend twice that on a second hand webcam with USB1 and 5 year old sensor technology. They work well, but they've had their day IMHO. Camera technology moves quickly..
  13. As above, you need to find the exposure control and turn it down.
  14. Beautiful details. What was the scope used?
  15. Align box around the image? During AS!2 or RS6? In AS!2 I just put align points on manually picking features of the image such as bands. If I try auto align it's way off! Works fine if all the processing is done through RS6.
  16. You need to adjust the R G B sliders in the camera settings to get rid of the green. So far a 3x barlow in 4x binning mode has worked best. Without a barlow then 640x480 worked for me too.
  17. I gave AS2! a go and then back to wavelets in RS6. Not sure what happened. Possibly it's from the later RS colour/contrast/brightness tweaks? The original version is much better IMHO. Also auto RGB align doesn't seem to work with an AS2! stacked image? Registax 6 AS2!
  18. Mostly it looks like the colours/contrast is a little different. Detail levels look about the same. I do like your natural processing style. I think some people over sharpen Jupiter with the Wavelets. Jupiter is supposed to look soft :-)
  19. I'll certainly let you know Chris. I had a quick read through the page and it's quire interesting. Though one thing jumped out that may cause an issue.. " I shot a raw photo with no light. Why does it appear all noisy, when it should be solid black? No matter how dark an image is? dcraw's auto-exposure stretches it so that one percent of its pixels appear white. The "-W" option avoids this behavior. I bracket plus/minus two stops, but all five shots look almost the same in dcraw. Why? See the previous question. " This auto exposure stretch won't cause many problems for regular photography, but for Astro use could be significant. I often bracket exposures of Lunar images to get the best detail, but if it's just going to try and make any exposure length look the same then there's probably going to be a loss of quality in the conversion?
  20. It certainly is! The sensor resolution is a bit on the high side for Planetary imaging, but you can ROI and BIN down to whatever you want. Still at full res it makes it very easy to find stuff!
  21. @ultrapenguin If that's a 640x480 box your Jupiter must be pixel resolution limited! You need a Barlow inline to fill up that sensor!
