  1. Hello all,as a totak noobie and not just green behind thr ears but all over ?. Ive had my first scope for 7 days now a 2nd hand skywatcher 200p dob, i only have the 2 eye pieces that came with it. I decided to go out in the communal garden again tonight asbthe sky looked good,i got out at 8.30 to give the scope time to cool down and get muself comfy. It was a lovely fairly clear night.And for the first time i managed to get Saturn in my finder scope after finally sorting out its alignment on friday, i started off with tue 25mm eyepiece saturn was tiny but i could cleary make out the rings i was gob smacked so happy and excited i quickly fumbled for the 10mm eye piece and slipped that in a slight adjustment of the scope and saturn was slightly larger and the rings alot more visible wow wow wow i am still on cloud nine it was amazing,i looked at it and followed it for what felt like half an hour.my wife bought me a cup of tea and she had a look to and a couple of my neighbours were very impressed. I then waited for mars to move round and quickly focused on it and i started with the 25mm and then moved on to the 10mm. Before tonight i wasnt very impressed with the 10mm but it did a good job tonight. Im still buzzing and im off to bed now. Just thought i would share with all you wonderful people. Many thanks and best wishes From me Dave ?
  2. For once I set up my two catadroptic imaging scopes together to see how they compared, and how well the smaller one cut through the crud. C8 SCT on SE mount, ASI 120MC, ADC, processed in Registax6, 3000 frame video. Celestron 127mm Mak on Nexstar SLT mount, wood tripod, ASI120MC , ADC, processed in Registax6, 3000 frame video. The 127mm images are slightly smaller, placed second. The bigger scope seems to do better. I thought that Saturn did not change much and was just a seeing test target, but the shadow of the planet on the rings is now distinctly asymmetrical. The dark smudges in the C8 Mars images correlate well with real features. Mars altitude about 11 deg. The dust storm seems to be over. The seeing was better than it's been for a while.
  3. Night of 12-13 June. I had not had a go at Saturn and Mars for some time, so set up the C8 to image them. Kit: Celestron C8 SE SLT, ASI120MC, ADC. Seeing: initially poor but improving through night. The Jupiter images were unexceptional, but the Saturn ones resolve the Cassini division well (compared with my earlier efforts). The rings look odd - I wonder if this is the conjunction brightening I have read about? Mars was very low when imaged at around 2am BST. I packed up because I was tired and cloud cover was forecast. I still got some surface detail.
  4. Greetings! I've had my telescope for a couple of months now and I still didn't get the chance to try the sky align option, I watched some video and tried aligning my scope many times but it never seemed to work. I only use it to watch the moon and I have to manually move it every minute or so because it keeps getting out of frame, how can I set it to track the moon on its own? I wanted to see Saturn a month or two back but I couldn't do it, I'm planning on trying again tomorrow as I'll know where it'll be in relation to the moon and mercury. Any tips you can give me? I really want to see Saturn. (Also, will my 25mm eye piece that came with the telescope work to see Saturn?) Thank you
  5. Somehow manged to coax reasonble detail with the help of an ADC despite the altitude of 14 degrees in West Sussex. I have looked at the firecapture log and a bit confused as to how it works out that the image was taken at f40. In the image train was a c9.25 scope, a skywatcher dual speed focuser, a x2 Barlow, astrosystems holland ADC then the zwo asi224MC camera.
  6. Hello again, just this night i went out to image saturn on my phone, and i got surprising results. I only processed 2 videos as of now but i think they were the only ones good for edit. Please give me feedback on the results, and also i posted my slightly improved jupiter picture here. On a side note i want to image the following reasonably visible celestial objects on my phone: the moon, the sun, venus, and maybe mars but i dont know how much detail i can see trought my specific scope. Also sorry for posting on the wrong forum, if anyone knows how to remove posts please tell me.
  7. 'Siyo (Cherokee for "hi"), all! In observance of the Saturn opposition, I'm posting one of my best videos from a few years ago. The Cassini division is apparent as is some detail on the cloud tops; it was an exciting capture! I hope everyone has a chance to see Saturn during this time! Clear skies! Reggie
  8. My time spent on Saturday 29th round about 11-12pm BST resulted in these images: Both are taken using the NA140SSF with televue 5* powermate (~f/27)and astronomik filters. Mars is Red and Saturn is L. Mars blue channel wasn't worth keeping, the frame rate on the ZWC120 was too low and the image so poor. G was better, L better still and R best. What is the best opportunity for synthetic here - re-use L as blue ? Both acquired in FireCapture for 9o seconds using image stabilisation and stacked in registax. I tried an alternate path of Pipp + AS2 but AS2 put some horrible artifacts around the limb that Registax didn't. I was surprised at how much detail came through on Mars and how poor Saturn turned out to be but it was really low. regs Mike
  9. My first night imaging Saturn. After going through all the AVI's this is my best result from the lot Sky-Watcher Skyliner 200p + 2x Celestron Barlow + QHY5L-IIC. 250 frames stacked in AS2! De-Noise in Registax. Wavelets & tweaks in Astra Image 4.0 24/05/16 UT 00:30:46 Lytham, Lancashire, NW UK.
  10. C9.25 and ZWO ASI224MC. Probably overprocessed for some but was pretty mediocre seeing and worse since
  11. Hiya ... despite being knackered yesterday (after a long day out in Weymouth hanging around while my eldest son did two shows in the chorus of the musical Joseph), I really needed a night out under the stars ... Got home at about 11.15, and was set up with the dob at around 11.30 (still twilight!). I started off with Mars and Saturn. Had a good look at Mars, but couldn't detect any detail. Saturn was fantastically crisp at x136 in the ES/82 8.8mm: clear Cassini division, surface banding ... The Milky Way soon appeared as a soft cloud overhead, lacking the fizzy sparkliness of other nights, but nice nonetheless. The Veil neb in my ES/62 24mm plus OIII filter was okay, not great. In fact, although seemingly clear, fainter objects and nebulosity was underwhelming (M31, 51, 81, 82, M16), and lacking in detail. Star clusters, though, were amazing. M11, M3 & lots of other 'couldn't be bothered to identify' clusters in the Milky Way were all fantastic! M3 (I know, not in the MW!) in the ES 8.8 in particular, was lovely; really dense, like fine salt grains ... The night was looking like it might be spoiled by a local 'party' that seemed to go wrong, with arguments and shouting emanating from a local farm, storming's off, more shouting, a girl crying, a shotgun blast (!), more crying, then drunken laughter, recriminations, then more storming's off, a pickup truck screeching off, then back ... honestly! Anyway, I was thinking of packing up around 1.00 anyway, as the waning moon was due to clear the hills, whereupon the 'party' seemed to calm down for a bit, so I thought I'd take a look at the moon before heading for bed. By this point I'd kind of resorted to scanning around with my 10x50s, and pointed them at the moon as it rose ... Then ... hang on, what's that? That doesn't look like a background star ... out with Stellarium on the phone and, 'Wow!' That's Neptune (in the same FOV as the moon!). What an amazing sight. I quickly switched to the scope, and tried a variety of EPs. The planet remained a shimmery orb, but a truly magical one at that. I hung around for another 20 minutes or so, entranced by the combination of our planet's satellite and the distant ice giant, before finally packing up. Amazing. As it turned out, I might as well have stayed out. Didn't get to sleep for ages, as I was buzzing from such a fantastic experience. Cheers, Kev
  12. We finally had a clear night here so I had a go at Saturn and Mars even though they are fading now. I used the C9.25 with a flip mirror and 2.5 Powermate with the ASI224MC. If only I could have done this earlier I'm sure that the results would have been better. Anyway, thanks for looking. Peter
  13. Having missed an idyllic morning last week, I spotted a gap in the forecast which looked like a clear morning sky coming. Not disappointed! I love a waning moon and arrived on site with the grab and go outfit at 3:30 to see the crescent just about 10 degrees above the eastern horizon. This got the first observation as it was bathed in amber hues from our air which give it a rich warmth. Aside from a few wisps and thin films, it was clear and cold. Seeing was good enough to push the mag up high. Jupiter was a beautiful marble at 85x. Two dark barges were very distinct. You know the seeing is not bad when the biggest obstacle becomes your floaters! Mars is looking fabulous though perhaps too low to yield details yet. This May should be good as we near opposition with Mars and Saturn and for us will be very close in the sky. I spent a lot of time just admiring the sky, though other diversions were well worth it: M13 is stunning! I have to shroud my face with my hands to block out any stray light to get best effect. And then those faint little needles of light start to identify themselves briefly. Funny how it comes and goes so must be atmosphere and optics at play. I still cannot get over how huge this thing is. Massive view at 85x and could have piled on more power. On to the Double Double which really needed the barlow at 170x to do the trick. Diffraction rings were not obvious which made me conclude the seeing wasn't as good as I had thought. Down to Steph 1 loose cluster and a quick look around the busy environs of the Ring Nebula. From here it's an easy jaunt down to Albireo with a spectacular show of contrasting amber primary to blue/green companion, which really came out at 85x. Then back to the moon which had risen along with Scorpio. I'm looking at my atlas now and just cannot figure out the huge crater near the middle that seems so prominent in this quarter. Must be the way the light is glancing across the terminator which makes it so much more prominent than the atlas indicates. Theophilus maybe. It has a peak in the middle of the crater. The Finale was Saturn by mistake. Thought this was going to be Antares so gave me a surprise at the EP! A lovely surprise and look forward to May when this is going to be much higher in the sky for observation. The real Antares was actually the last view in the scope before packing up and this is an unbeatable M class. Clear skies
  14. Hey guys Just wanted to share my latest go at imaging Saturn. This was the first time using my ASI120MM on Saturn. The image was taken with an Orion XT8G + ASI120MM + 3x Meade Barlow + Astronomik IR742. Date: 30th June 15 Time: 9:05pm PIPP + AS!2 + Registax Any feedback would be great. Saturn by Enrico Danieli, on Flickr My previous image was taken 10 months ago with a Logitech C200 webcam. I'm very happy with the improvements.
  15. I've been working on this one for a while on and off. It's gone through various rounds of PIPP, stacking, drizzling and PS re-sampling. The colours are not right but this is the best resolution I've yet gotten from the C8 tube. And I'm a little impressed myself, so I thought I would share :-)
  16. Saturn seen from London on a windy March night. It's still a bit too far for me to get a more detailed shot but this is my best attempt so far.
  17. Hello Please find my first attempt at Saturn. Advice needed on how I can improve capture and processing. My adventure started at 6:00 am this morning taking on -2C ice and frost, to capture Saturn in the South before sunrise. The transparency was good though and the stars looked really crisp against the still dark sky. (Exciting!) I managed to capture two run of 39000 images at 65FPS at 15ms exposures, raw mono data. Using my 127mm Mak (1500) with a 2x Barlow to get it up to 3000mm Anyhow just finished processing, process followed was. (Was done in a bit of a rush.) Dark Frame 10000 stack at -2C Reference Frame AS!2 - 25% using 4 quality setting, sharpening and mix in raw 50%, REGISTAX - Wavelets and gamma adjusted, Histogram stretched. Main Frame AS!2 - 50% using 4 quality setting, sharpening and mix in raw 50% REGISTAX - Wavelets and gamma adjusted, Histogram stretched and increase size to 1.5 I have been a bit aggressive with my wavelets and placed this on a black background, with a bit of mid-tone adjustment. It feels a bit blurry and very yellow, not much in the blue channel, is this normal? Do I need I need to up my FL to from 3000 to 4500? Lack detail for +-20000 images, should I up the exposure and reduce the images? I am being overly critical for my equipment? Thanks for the feedback, appreciate it guys.
  18. Friday the 7th was my last chance to photograph Saturn, as light conditions and position become increasingly less favourable for imaging. Indeed, it's pretty bad already, as the following images from that session where shot directly through the strong halo of a "beautiful" and "oh so useful" street lamp. I went for full on luxury that evening, with a deck chair and a table for the laptop, might as well treat myself as I gaze at a planet a billion and a bit kilometers away! The evening was even more delightful as I set the scope up to have the neighbours kids curiously ask me what I was doing and thus I took the time to show them the view of Saturn, much to their delight - and mine, I love sharing this stuff with interested minds. Saturn has not been well positioned for us here in the UK, with it peaking at just over 25 degrees in the sky, but at this peak, around 22:25 UTC, it's pretty light outside. I have only just started imaging using the ASI120mc, but finding it a joy to use with FireCapture 2.3b. Indeed I can't wait for a little bit of Moon or for Jupiter season to start! Overview of Imaging Seeing: http://youtu.be/UUbr1KKhsTc (Video is RAW Footage, but Debayered GRGB for colour) Hardware: Meade LX90 8" SCT | Drift Aligned with no computer guiding Meade 2x Shorty Barlow ASI120mc @ 30ms | Gamma 50 | Gain 62 | ROI 496x320 Software: FireCapture 2.3b PIPP: Colour Debayer GRGB | Crop | Center Registax: Align | Stack best 30% | RGB Align | R/B Correct Photoshop: Levels | Saturation | Smart Sharpen | Soft De-Noise I have also included an RGB split of the RAW TIF file (with a basic smart sharpen applied) - I note that R,G are sharp (R being the sharpest), yet the B channel is particulary fuzzy. I assume seeing, it's low position and possibly the street lamp have caused this?
  19. I have recently taken delivery of the ZWO ASI120mc 1/3 cmos colour camera. First thing I will say about this camera,it's significantly better than the Orion Imager IV, very easy to use and works a charm with FireCapture 2.3b. Last night I had clear skies and a low wind, so I set about capturing Saturn as it drifted past my local street lamp collection. Was an absolute pleasure to sit in 12c weather and just watch as Saturn bobbed around in my view. After eventually packing up and transferring the files to my primary computer, I hit the hay and processed the images today. The result is much better than I ever achieved with the Orion Imager IV, however - my collimation is WAAAAAAAAAAAYYY out (well it's not good), the Red channel of my image is sharp, the Green, blurry and the blue is displaying ghosting and super fuzzyness. So, whilst it's not a complete stunner, and tonight is going to be spent trying to figure out this collimation lark - I present my first Saturn with the ASI120mc, first is the full colour and then just to show you how sharp the image could have been, the red channel.
  20. I finally managed to get out last night and do some imaging. The seeing was really poor after quite a nice day, but hey, at least the clouds kept to the horizon for most of the session. C8 (XLT), CG-5 GT, Revelation Astro 2.5x barlow, SPC900NC, Baader neodymium filter. Captured at 10 fps, stacked in AutoStakkert with wavelets in RS6 and some tweeking in PS7. I think I probably pushed it too far with the 2.5x barlow from reading replies/suggestions to other peoples pictures. Next time I get an opportunity to try I will leave the barlow off. Any comments/suggestions would be gratefully received & thanks for looking.
  21. Hello Stayed up last night, I had a tiiiiny observing session. Then came in only to see that it would be clear in the morning. So I stayed up and around 4 set everything up for a pass at Saturn again. Conditions were poor, but I dont see them improving with Saturn so low so no need to moan. My camera seems to have gotten even more filthy... I really need to sort it instead of wimping out!!! Anyway this is I believe around 4000 frames stacked then cropped. Only the first avi I've gone through but I dont see it improving. Taken with 200p, with standard 2x barlow and a massive homemade extension tube (how far can i push this barlow aha?). With point grey firefly mono, no filters. Dan
  22. Lovely dawn this morning. Full Resolution image, with "mouseover" label option, at: http://astunit.com/tonkinsastro/planets/20121211_planets.htm
  23. Almost certainly my last Saturn attempt this year .. just skirting my rooftop now (oh for a south facing garden with fields beyond !) Switched back to the C9.25 for convenience and results very similar to 10" OO Newt considering the poorer seeing on this imaging run resulting in very noisy captures. C9.25 F25, DBK21 618, IR image using SPC 618 modded, AS2, Reg 6 Cheers, Alan
  24. From the album: Solar System Objects

    This is quite possibly my last Saturn for 2018. The only reason I would image Saturn again this year, is if in the next couple of weeks I had exceptional seeing. In that case I will resume the attempt to resolve the Encke division with my 8" scope, which I do have hints of in images so I'm confident that it can be done.
