  2. Finally got decent images of Jupiter with my CPC800. I was beginning to worry that I had invested in a setup that was inferior to my C8 SE.? The CPC800 mount is far nicer to use; it's much easier to get the image on chip and keep it there. And the GPS saves some time and effort. CPC800, ASI120MC, ZWO ADC, captured with Sharpcap, processed in Registax6. Note the Io moon & shadow, a circle near the middle of the southern cloud belt, and on the second image looks like the GRS just coming into view. Also got an image of Saturn - I have always found it hard to get a decent sharp image of Saturn (lower frame rate?)
  3. Imaged through my 12" newtonian and using a JAI machine-vision industrial camera I borrowed from work. After processing I noticed hints of altogether four Saturnian moons. Seeing was rather poor though.
  4. Some reasonable seeing from my location in Selsey, West Sussex over the last couple of nights. Here are three results for Mars, Jupiter and Saturn from 26 June. Pete
  5. Hello All, Here is another of my contributions to the planetary imaging contest... this is Saturn taken on 6th June 2018 with my quest to image the Encke division with my 8SE. No Encke division.. although there is a hint of it there.. but I did manage to capture what looks like a storm developing in the edge of the polar region. Taken with a my 8SE - 8" SCT with the Skyris 618C at F33. Clear skies.
  6. Saturn - 12 subs (10x ISO400 1/15s & 2x ISO800 1/40s) run through PIPP for aligning & then stacking & wavelets done in RegStax 6. Taken using my Olympus E-510 with an M42 Sunagor 400mm preset Telephoto f/6.3 lens & x2 TC attached. Effective aperture f/12.7. Saturn was quite low in the sky, seeing was not optimal & the sunrise was starting to turn the sky blue. Image is very small 200px square but I am very happy I can make out ring definition all thing considered. Visual Magnitude: +0.5 Apparent Size: 16.2 arcsec - 99.8% illuminated Distance: 10.248948AU - 1533.2 million km - 85.24 light min Saturn [2016.02.18] by 1CM69, on Flickr
  7. 3rd June 2015 Equipment: NexStar 8SE 18:16 - 19:30: Venus was approximately 30 degrees above the west western horizon. Bright and unmistakable. Through the 13mm TV it was a bright creamy white half phase with a hint of markings along the terminator extending about a third of the way toward the edge. Markings faded out toward the north and south poles. Tried imaging at F10 & F20 using a mono CCD DMK21au618 through IRPass 685nm, Neodymium and UVenus filters to combine as RGB. IR Pass and Nd were bright in both focal lengths but UVenus was very dim had to be pushed to full gain and shuttle slowed down to 1/7 f20 and 1/15th F10. Between 19:30 and approx 21:00 Saturn was only rising, about 45 degrees in the east and was moving behind a large tree in east obstructing view. Add to that that sporadic clouds were moving toward Saturn from north-west so I waited to see what will happen when Saturn rises above the tree blocking the view. Luckily the clouds cleared mostly when Saturn was in prime imaging and viewing position. 21:00-23:00: Saturn was a sight to behold. The seeing was one of, and most likely the best I have ever seen. Using 11mm TV the view was sharp, bright and detailed. 7mm just like with 11mm TV sharp and detailed. 5mm again sharp and detailed. 11mm 2.5X PM sharp and detailed. Sharpest and biggest most detailed view. 5mm 2.5X PM started to go soft but still this was at 1016X mathematically but in reality 700-800x since the 2.5X PM seems to magnify less then the 2X Barlow... Due to length of tube. Color was visible, so were clear cloud bands in the atmosphere along with the details in rings. The Cassini division was crystal clear all the way around the ring, only covered by the globe behind the planet... At times I thought I saw the Encke division at 460x (11mm TV & 2.5X PM) perhaps it was wishful thinking since imaging did not reveal it at F20 or F50, but the view was still and crisp. I spent about 90 minutes+ just staring at Saturn, couldn't pull myself away from the eyepiece. 23:00-23:30: The Moon was the last object observed and imaged. Just past full moon, the side with shadowing was crisp at all powers used from 180X - 406X. It's been a while since the moon got some attention, last time was during the two Saturn Occultations last year. I imaged using f10 and DMK21 through IR Cut... Created a 10 plate mosaic of the contrasty edge. Very cold, couldn't feel my hands by 23:30 when I packed up but was a great night of imaging and viewing. MG
  8. 14-15 May 2015Equpiment: NexStar 8SE On the night of 14/15 May as I continued to image Lamda Centauri nebula through the Sulfur single Ion filter through my refractor, I had to keep an eye out for passing clouds.. there were moments when thick clouds moved 15 or so minutes at a time over the patch of sky I was imaging, so I had to be near it to stop the exposure as the clouds rolled in then start it as they went away….Autoguiding of the running chicken nebula was done by OAG and Celestron NexGuide. So I thought, one thing I haven’t done in way too long was do some nice old fashioned eyepiece observing…. I set up the SCT on the Alt-Az mount I’ll tell you I had some awesome views… AWESOME…. First I looked at Saturn…. It was bright and massive at 406X magnified… clearly visible was the Cassini division in the rings, the cloud belts and ring shadow on the globe and 6 of its moons around it…. then after about 30 or 40 minutes of absorbing that view I moved onto the Omega Centauri… first with the low power 50X magnified… the globular cluster was clear, and a clear fuzzball of stars in the eyepiece circle…. Then I tried the TV11mm Nagler I recently received. The view in high power… what I saw has to be seen to be believed, at 185X not only was the globular massive and the individual stars were resolvable in the CORE!!!! The Core!!! But because the eyepiece is wide view the circle was not visible, it was almost out of the peripheral, so it was like looking into space through a window…. Awesome…. Then I went toward the Jewel Box near the southern cross… at low power the distinct “V” shape of the Jewel box was obvious and the different colors of the stars were visible. But with the high power eyepiece not only were the different colors of the stars visible and glistening but there were so many stars in the view that the “V” shape was almost lost, why it’s called the “Jewel Box” was plainly visible. Next target was the Carina nebul. Here I had to use the ultra high contrast filter to dim out the stars that overwhelm the nebula and I bs you not, with the filter there were actual whisps, folds and structures are visible within the nebula… stuff normally expected to need to be long exposed to see, but were visible through the eyepiece! Before those four I just described I looked at the Lagoon Nebula, the Trifid nebula and the butterfly nebula but those were too low into and toward lights from CBD so the details were washed out, I still saw the “lagoon” in the lagoon nebula but not as defined as it would be at a dark location or position in the sky. The Trifid and the butterfly were just a barely visible smudge. The butterfly had the shape of it visible but only barely. I remember when I took the scope to the mountains and looked at the Trifid nebula from there, the shape of the Trifid was clearly visible as well as the breaks in the “flower” part, tonight was not even close. I’ll tell you... it doesn’t seem like a lot of objects were looked at but more than 3 hours went by like nothing…. I didn’t feel that my bones have frozen through until I realized what time it was and that the object I was imaging moved behind the trees and buildings in the distance. In the last few years I mostly did astrophotography but after tonight I think I need to do more traveling to dark sites and do lot more observing. MG
  9. According to NASA the length of a Saturnian Day is unknown...who would have thought ?
  10. I just ordered the SkyWatcher 200P Dobsonian from FLO this afternoon and after reading a lot of reviews on this model definitely believe I made the right choice ... Does anyone have any suggestions on the maximum ( or maybe " reasonable " would be a better word ) magnification for the planets , specifically Jupiter and Saturn ? So far with my Meade Infinity 600/90/f6.7 refractor and the 6.3mm kit lens I see both planets at around X95 magnification which shows the bands on Jupiter and that fainter , thinner band 2/3 up on Saturn ( anyone know what that one is called ? ) and also the moons too ... What has proved to be elusive so far is the famous red spot on Jupiter and also the Cassini division on Saturn's ring system ... Has anyone ever even tried the maximum magnification of X406 on the planets or would that be only really usable on the Moon . Any advice would be very appreciated .
  11. Happy Equinox, everyone! Here is an image of the last quarter moon and Saturn I snapped at dawn, shortly after the spring officially arrived for us in the Northern Hemisphere:
  12. Well I'm still at it with the Xbox 360 webcam but this time using Firecapture and without Barlows. What I did notice while processing was most images didn't need RGB align. The only downside was a smaller image to work with. Conditions seemed average to good. Celestron Nexstar 8i, 2 short extension tubes and Celestron UV/IR Cutoff filter Mars 30fps, 3000 frames from 6000 stacked in AS!2, wavelets in RS6, finished in PDN. Saturn 17fps, 2000 frames from the best 4000 using PIPP from 9000 total, stacked in AS!2, wavelets in RS6, finished in PDN. The next image is a single best frame from a video that has been sharpened slightly, noise reduced and levels adjusted in PDN. If you're wondering about image scale, it is enlarged. This was a test to see if I could get better detail, sharper images from my Celestron 8i without using Barlows. I don't believe I did. The only other thing I can eliminate out of the equation is the UV/IR filter? So it looks like I'll be on the hunt for a another scope for imaging 10"+ SCT. The Edge HD's are likely the go unless there are better in the market. Any suggestions?
  13. First Saturn of the season. A slightly more successful night's imaging but it was still touch and go with uninvited cloud mucking up the shots, so this is cobbled together from the best frames of each video. Saturn reached opposition on the 2nd June so this is the best time to view and image it. Image made from 3 videos - a total of 6076 frames Captured with FireCapture Processed in PIPP, AutoStakkert, Registax, and Photoshop Equipment: Celestron NexStar 127 SLT Skywatcher EQ5 Mount ZWO ASI120 MC imaging camera
  14. Its a little depressing that Saturn is sooooo low in the sky but managed to get a few pics on the 25th when the seeing wasn't actually to bad. Not to sure what the blue frames all about! All done with 250p QHY5L-IIc, processed with pipp, As2, PS The First 2 with 2.5x barlow the last with an extra extension to make 3.5x mag
  15. Hi All, Just sharing my results from tonight. Once again I was lucky enough to have very clear skies. I was observing Saturn through my 8SE and I kept on pushing the magnification to beyond the 450X mark and beyond with perfect views. With the 5mm eyepiece and the TV 11mm type 6 + 2.5X powermate the view was amazing... crisp and detailed. I thought I'd be stupid and put the 5mm and a 2X barlow to see what will happen, and even though the image was quite soft, Saturn was MASSIVE... of course that was 810X... but to my surprise I was still able to make out a brightish cloud band and the cassini division. With such a steady atmosphere I had to try to image it and I think these Saturn images are the cleanest I captured so far, so I thought I'd share. Work flow was I imaged the F20 pic through a Celestron 2X Barlow and the Skyris 618C CCD, and the F50 image was captured using the DMK 21au618 and a 5X powermate. The mono F50 image was used as luminance on the color data scaled up which was captured with the Skyris. I'm very surprised at the quality of planets I'm getting with the Skyris for a OSC camera. Image processing was done done in PS, Stacking in Autostakkert and a very small amount of wavelets applied in registax 6. I suspect I'm pushing my 8" SCT to the limit, or close to it, but if anyone has any advise or tips on how to squeeze out and more detail, please share. One feature I was chasing for over a year now was the Encke gap, I feel like I'm right on the verge of capturing it but perhaps my mirror is just slightly too small for it. Thanks for looking...
  16. Found this Saturn Avi amongst a load of Mars Avi's I have yet to process from April . 650 frames from 2000 stacked in Registax 5.1. I was used the Spc880 and SW 200P, weather condition were awful as was most of April as you all know, just glad I have some more Avi's to play with whilst the weather bad. As always all comments welcomed, never to old to learn new tricks! thanks for looking. clear skies!
  17. I has some serious issues getting the gear working last night. PA was not a big problem, but getting the ED80 to co-operate with the star finder and get everything balanced was a little nightmare. By the time everything was ready to go the full moon started to brighten up the sky. I decided to have a quick go at Saturn knowing it was a lot to ask from the scope and these are the results using TV2.5 Powermate and after using AS2! and a little PS. Drizzled 3x But I know these are nothing to compare with the previous poster's very impressive C11 shots.
  18. Hi all, Here's a Saturn RGB captured from the night of May 6th under much better seeing conditions than of late. Saturn wasn't a fuzzy blob which is always a bonus!! Pete
  19. I first observed Saturn back in January 2011, I had owned my telescope for about a month and barely used it due to weather and an initially broken DEC drive. Of course, eager and somewhat inexperienced I plugged my Nikon D300 and snapped some photos, only to be sorely disappointed: Two years later, it's the same telescope, I've got more equipment, ranging from an Eq wedge, to barlows and filters and am generally starting to get to grips with more. Last night I set my alarm for 4:00am, awoke only to see a thin cloud layer and laid in bed for 30 minutes fighting the urge to sleep watching to see if the sky would clear. They did. I dragged myself out and set my scope up, observing Saturn for about 30 minutes, I plugged in my Orion StarShoot Solar Colour Imager IV (SSSCIV) and got my first ever view of Saturn on my laptop. Recording 3000 frames, I then attached a 2x barlow and carefully centered Saturn, attached the camera,...nothing! I carefully went through the full focal range of my telescope, nothing, I set exposure and gamma to the extreme, re-centered, nothing! Frustrated I went back to prime and it was there, this went on for about an hour, with the 2x, 3x barlows and every time I had a barlow in play, Saturn wouldn't show. I did at one point get it to show at 2x, even seemed reasonably bright (f/20) and noticed that the image would flicker in and out, like every few frames it simply couldn't detect Saturn. Seeing was bad, Vega and the eventually rising moon rippled madly and Saturns rings danced constantly. So the below image is from the single 3000 frame capture I took, focused by eye and stacked using Registax with a Smart sharpen filter applied in photoshop. Optical Chain: SSSCIV > Meade LX90 8" SCT > British Winter Atmosphere > Space > Saturn.
  20. Hello, *Touch Wood* the weather looks like I'll have a shot at Saturn tomorrow, although my faith in weather forecasts is dead. Anyway I've realised that after waiting so long I'm not sure how many times I will be able to have a go at Saturn so I'm asking for some advice on a couple of the camera/webcam settings: I use a Point grey firefly monochrome camera and flycap 2 software. 1. Currently I use "Pixel / Resolution format" Y8. This allows me to shoot up to 60fps. However I can also set it to Y16 (16 bit i assume), which limits me to 30fps. Would 30fps and Y16 be the way to go or is Y8 and up to 60fps better? 2. Also I currently don't use the histogram, I just sort of judge it by eye. However I had a sneaky look at it with Jupiter. On the y axis is percentage and the x axis a load of very large numbers. On Jupiter the other day it was peaking around 50% on the y axis, a very sharp peak. This about right? I've heard more than 50% but surely this will introduce a lot of noise? Thanks, Dan

  25. Hello Astronomers, On the 12th August, between 18:34 and 19:21 we had a occultation of Saturn by the moon. Of course I couldn't miss out of such a event so I took the day of work and setup my gear so that I could simultaneously capture the event as well as observe it. I had the SCT recording with the 618C while observing it in the dob... literally at high power it looked like a Saturn rise... massive lunar horizon filling the field of view with a big Saturn rising from under it, literally animated and visible slowly moving up... Looked amazing in the eyepiece... Photos or videos don't even come close to how good that looks live in the ep. I had my eye on the eyepiece in the 14" Skywatcher during the occultation and recorded the start and finish times as soon as I noticed them: Occultation Start 18:35.51 AEST Reappearance Start: 19:19.37 AEST Occultation Finish: 19:21.20 AEST I stuffed up the first part video, the covering of Saturn because I still had iCap set to capturing a maximum of 5000 frames left from my planetary imaging, so at 25fps I barely got a 3.5 minute video that stopped just before the actual occultation started... yes I was kicking my self... but at least I watched it... I wasn't going to do the same mistake on the re appearance on the other side... Sharing with you my photos and the video of the event... video is sped up to 400%. Clear Skies.
