  1. Hi guys Help please. Last night I purchased an old celestron c8 sct, 2000mm fl, f10 on a fork mount. The mount has no power cable so is pretty useless, but i brought it to defork the ota for planetary imaging and hopefully some small faint dso's. It was a reasonable price. Ive got a heq5 pro mount that i will be mounting it onto. The guy said it needs collimation. I know i need to mount it on a vixen dovetail but the bolt holes dont line up anywhere. Its as if someone has rotated the corrector plate housing around 120 degrees. Would it make a huge difference if i removed the housing screws and put it back so that the bolts line up, keeping the mirror and plate in the same spot on the housing bracket, or would i have to try put everything back separately in different positions and collimate everything from scratch. The picture at the minute doesn't quite get crisp so whatever has been done needs rectifying. Can this even be done by us regular folk? Any thoughts or ideas, instructions? I feel the plate could do with a clean and the primary mirror itself. I just want it as optimum as possible. And can a hyperstar be fitted to these older versions? Im literally starting from scratch with an sct setup. Also what type of camera would suit a scope with this focal length for faint dso's, i have a gp290c for the planetary side of imaging. Sorry for the bombardment of questions.
  2. Hi there! I am seeking for advice from you good people. I want to create a setup for stargazing which is fully automated. Ideally every process like scope calibration, guiding, tracking, focusing and taking photos should be done through WiFi, preferably from an iPad tablet. Planetary imaging is the main purpose. I don't really care about deep space imaging. I want the whole setup to be rather cheap, small and light, at the expense of imaging quality. I am a total noob (used to play with an ETX-70 lots of years ago), but I really need the functionality I have described above. I am thinking of using the bellow components and kindly request that you correct/add to the list: 1) AstroFi 102 2) A ZWO camera suitable for planetary imaging (any ideas for less than or equal to $250) 3) An auto focuser and motor drive (any ideas) 4) Smth like an ASi air device? Is a guider necessary for planetary imaging, by the way? Do you think I am in the right path? I still have not been able to really comprehend the full picture. Is what I am asking for doable? Thank you very much in advance!
  3. which webcam is best for planetary imaging under 25 USD . If you have experience of any webcam for planetary work please help me out
  4. Hi guys, I managed to get this picture last night using my Celesteon SCT 9.25, with an old Cannon Rebel camera which had a x2 Barlow attached and went into the diagonal. Not sure what the expose time was but it was very short as longer exposure made it white with no orange band detail. Just edited the image on my iPhone. No stacking nothing. Can I expect much better pictures with my kit? If so how? Many thanks Paul
  5. Hi All I have recently bought a QHY163C and sold my original square QHY8 which I had had for a few years Nothing wrong with the QHY8 and I was reasonably pleased with the stuff I did with it...but itchy fingers/wanting to try something new/set cooling point/ heated window etc tempted me and I have just sold the QHY8 Most of the Photography I do is deep sky but I have had a dabble at Luna and Jupiter with various webcam type cameras and currently have an Imaging Source DBK21 AU04 (colour) What I want to know is how will the QHY163 compare to the DBK21 on planetary and moon pics? I have read that the 163 is suitable as a planetary cam as it is capable of high frame rates and 2x2 binning and wondered if anyone had used both types...ie a Largish Chip DSO cam that can also do planetary against a dedicated small chip Planetary cam. If I can expect as good or better pics with the 163 then I might as well sell the DBK21 Unfortunately due to weather etc other than bench testing the QHY163 I havnt used it all on anything yet. Thanks Tom Start new topic
  6. I was trying for a SPOT, I got 2 anyway and what I saw on my laptop is what you are seeing . Just a screengrab no avi's all my time was spent getting my rig just right so the next time out imaging it'll be smooth.
  7. Attempt number 2 at processing Jupiter. Finding it incredibly frustrating trying to image with my current set up, so have invested in 'Making Every Photon Count' to help me decide what I should upgrade to! Composite image of Jupiter and 3 of its Galilean moons Canon 70d, 8" Dobsonian (prime focus and manually tracked) 1 x 30 sec video, stacked, for Jupiter I attempted eyepiece projection, but couldn't achieve focus... no doubt I am doing something wrong, but couldn't work out what!
  8. Hi everyone. I recently acquired a ZWO ASI120MC-S and so with the bright summer skies I've turned towards solar and planetary lately. I'm not great at either, but I'm learning This is the result of my efforts from last night and I'm quite pleased with how it turned out given it was ~3-4 hours of sitting in the relative cold of my front garden. I've never managed to time weather & my availability with the GRS or a Jovian moon transit before so that's two firsts for me. The seeing was "soupy" to put it lightly, especially towards the end when the planet got lower in the sky and ended up over the roof of a house across the road, but I can't complain - at least it was clear! I took a video around every 5 minutes for almost 2 hours, stacked the best frames, then compiled into an animation of 19 frames that loops back & forth. Io started off about 1/3 of the way across the face of the planet when I started recording data so it's a bit tough to see but you can follow it back across once it pops out the other side. Thanks for looking! I hope the attachment works correctly because I couldn't seem to get the gif size down below ~14mb, so I apologise to anyone on a slow connection!

  9. Only my second time observing Saturn last night so thought I'd try imaging it as the sky was nice & clear for once! All taken with Sky-Watcher Skyliner 200p + 2x Celestron Barlow + QHY5L-II-C. 100 frames stacked in AS2! De-Noise in Registax. Wavelets in Astra Image 4.0 Cropped & tweaked in CS6. 23/05/16 UT 23:55:23 Lytham, Lancashire, NW UK. Here's my second attempt. ROI was smaller so it gave me a slightly higher magnification. 120 frames stacked in AS2! De-Noise in Registax. Wavelets in Astra Image 4.0 Upscaled & tweaked in CS6. 23/05/16 UT 23:56:14 Lytham, Lancashire, NW UK.
  10. Hi All, after years of pressing my smartphone camera to the eyepiece and taking pictures of the moon I tried attaching my DSLR (An old entry level Canon) to my Skywatcher 200 (1200mm focal length) on a dobsonian mount. I could not achieve focus whichever way I went. However, it seemed that what was needed was to be able to move in more than was available. What am I doing wrong? How can I get the camera to focus?
  11. some questions i probably should know if i bothered to pay attention at school. do all planets rotate in the same direction ? do all planets orbit in roughly the same plane in relation to earth ? if jupiter takes roughly 12 years to orbit the sun why does it travel so far in our sky in such a relatively short period of time from our perspective? i presume because earth travels faster and overtakes it ? if the universe is expanding is earths orbit moving away from the sun , and is jupiters gravitational pull having an effect on us since it is so much bigger ? why do i taste frazzles 3 days after i have eaten them ?
  12. Having had another go at imaging Jupiter, I used both a Celestron Ex-Cel 2x and an unbranded 3x barlow. Comparing the results of the two, the 2x drizzled 1.5x looks better than the 3x. I guess I'm stating the obvious that all barlows are not equal, but the question then is, how do you choose one? Given I have a Meade 8" SCT as my primary planetary scope (2000mm focal length, f/10), I'm thinking about getting a nicer barlow at or above 3x specifically for use in planetary imaging. Any specific suggestions?

    From the album: My (very amateurish) attempts at astrophotography!

    First attempt at Jupiter - not great, but it's a start! Canon 70d mounted to 8" Dobsonian at prime focus 30 sec video, stabilised in PIPP Stacked in Registax
  15. So I'm looking for the best grab and go planetary viewing (and maybe some DSOs) telescope that is relatively cheap (below 500$) that will also support some Astrophotography. I know the SkyMax 127 is a Maksutov and therefore has a high F number, but I'm okay with that because I'll just pop on a 0.5x focal reducer to bring it down to F/6 (still a bit high though.) With said Grab and Go I'm interested in viewing Saturn and Jupiter with high detail. What do you recommend? Clear skies, Leon. Edit: I need one that'll fit into the Sky Watcher EQ5.
  16. My skills are lacking and what better way to improve than to process some older archived data from April of this year. This was taken with an 8 in. Newtonian astrograph , lxd55 mount , Spc900/3x and 6 attempts w/ reg6 on auto and 1 attempt going through and picking which frames to stack from my clipboard. Colors are still giving me trouble getting them just right and in the right places.

  18. The wildfires here in NC have put a damper on my imaging but , I've got a Z10 reflector that has been getting a workout scanning the skies . Here are 2 that I took the 14th and 15th of April with an 8 in. Newtonian/lxd55 mount/Spc900nc and 3x barlow . It seems that I've forgot to get the settings correct and had to check out astronomy shed , so next time they'll be better . I ran them through but, when I put them in reg6 I just got a lil' black screen so I just ran them through reg6 and my rgb align and balance need help , it was either too blue , too red or gray. I chose to leave the red where it was and get some help besides the videos I've watched. I'm getting better at this every year I collect data on Planets.
  19. I'm trying to get better at imaging Jupiter with my spc900nc and a 3x , I've not tried the 5x powermate yet, does anyone use a 5x on a webcam or is it just too much power? These lateral lines are just killing me is it because of gamma or gain set too high? This is caoptured with Sharpcap 2.8, any ideas rwg?
  20. Excellent seeing on the 16/17th which allowed the use of a 5xbarlow on my 200p Got the best jupiter image so far, pleased with the result
  21. Apologies up front if this is a little long or rambling. There are some conclusions at the end if you want to skip ahead. Last night I got the chance to try out my new WO binoviewers. Having read some posts on the forum about the benefits of binoviewing I’d decided to put them on my list and to get some to improve my view of the planets now and in coming years. Setting up both scopes (a newt and a frac on tracking mounts) at around 10.30pm I was just aiming to make this work with both scopes and to see whether they needed the 1.6x barlow that’s included in the box to achieve focus. If that went well, then I’d see what kind of difference they’d make to observing planetary targets. Jupiter was waiting. Firstly, the build and feel of them is good. The eyepiece holders are focusable and smooth and there’s nothing flimsy. Inserting the viewer into the newt it quickly appeared that I didn’t have enough back focus to get an image. Hmmm. Ok let’s try the Frac. Again, no joy. I even removed the spacing rings on the frac focuser… close but it’s not quite there. So, a quick rummage through my bits and pieces and I wonder, how about trying the element from the ES 2x barlow I have instead of the 1.6x? Well amazingly yes. That’s focussed, and wow. The viewers come with two 20mm eyepieces but with the barlow the image scale with Jupiter is good and the planet and its closest moons fill a nice portion of the field and the planets disc seems about the same size as I’d expect using a 5mm eyepiece. As I sat and tweaked the focus the grs and the main equatorial belts began showing some more detail and colour, and the temperate regions the same. It’s obviously a good seeing night as the whole planet seems mostly stable with just occasional wobbles but I’m really picking up more detail at a better scale than I have before. The images come together nicely and although it is a bit dimmer than with just one ocular, on a bright target like this that’s no bad thing and there is no squinting or need for an eye patch or anything else to distract. Very relaxing. I try a couple of 12mm celestron plosyls to see if I can up the image size. The result is not great though; bigger yes but mushier and the narrower field of view really feels uncomfortable compared to the 66 degree supplied eyepieces, so it’s quickly back to those. It’s at about this point that I get buzzed by a couple of dozey cockchafer beetles who seem to want to break into my kitchen by headbutting the window until something gives! I’m also getting pretty dozey and although I‘m desperate to wait for Saturn and Mars I decide to pack things up. It is nearly 2am. The evening’s highlight though comes just before I pack up and I see a distant bird (maybe an owl) fly in front of Jupiter’s disc! It only lasts a second. I’ve seen the occasional one when viewing the moon but never this. Really unexpected. Conclusions. Did they work straight out of the box with my set ups? Well no, but a bit of fiddling and I got there. I kind of expected that. I’ll try a few other combinations next time and see if the 1.6x element will work. Are they good quality? Well they seem solid and give clean and clear views. So far so good. Did binoviewers improve my planetary viewing? Yes. If future nights are only partly as good I’m converted. I was very impressed with the views of Jupiter this evening. Probably among the best I’ve ever had in terms of detail and the scale at which I saw it. In part that was down to the conditions being good but also, I’m sure down to the fact that I could relax both eyes and just wait for those better moments to see what’s really there allowing me to see more details on those belts and the spaces between. I’m really looking forward to the next opportunity with the planets and bring on that devil’s light bulb I say! Thanks for reading. Dan
  22. Hi Stargazers, After a lot of work and help from the great Damian Peach I managed to get some really good images of Jupiter Mars and Saturn despite a total spend of just £100... and I made another bonkers Astrobiscuit video about it which I hope you enjoy. Mr Peach really helped me pick my nights to image and the other big surprise was how good the canon 600D is at planetary. All comments/ advice/ criticisms most welcome...
  23. I've learned a lil trick to getting the object in the fov of my cam and it wasn't the best night to be imaging but, I had to do it anyways just for SaG.
  24. Hello! i am seeking the help of those with experience in refractors please!! I have been an amateur since i was just a wee lad, i have always owned catadioptric and reflectors of many types, unfortunately short of my current Lunt LS60PT and the department store pea shooter i had as a 12 year old and my which spent way more time peering through windows in the apartment complex across the street than gazing at the sky i have NO experience with refractors. This is where forums like this come in, ok this is what id like to do, my budget is around US1,200, for this i would be looking at a doublet no doubt, i would like it to be in the F5-F7 range? this would offer some flexibility for both visual and future basic AP dabbling. I mainly would like this refractor for planetary, lunar and double star observing, i do hear that nothing beats a refractor for these objects and I'm itching to see for myself. I realize that this budget will not get me an NP101 or any other triplet for that matter, but i would like the best for that price in the 100mm range preferably since id love to stretch its legs on lunar and planetary. i also own a 12" lightbridge but this is definitely not a grab and go scope which is what id love to have now, CA would be an issue not so much for visual but future photo work id like something that performs reasonably well in the CA department. if anyone out there has had much experience with refractors id love to hear from you! Thank you all!!!
  25. Would anyone care to recommend an 8 mm EP to complete my collection. Will be used with the 200 Dob and primarily for Planets. I really like my WO 6 mm but they don't make the 8. The Vixens are fine but again no 8 I am not a great lover of Barlows.
