  1. Hi.if you think of splitting i may be interested in the 6.3 reducer.good luck with the sale.


  2. Hi, I have decided to part ways with the hobby as I just don't seem to be able to take out time and my equipment can be put to better use by somebody else. Offering a nice bargain below: Celestron C8 - 6x30 finder scope - 7x50 guide scope (taking from 200P skywatcher and modified with the correct adaptor at the back to turn it into a guidescope) - Guide Camera (QHY5 II) - Hand made dew shield (free) - Focal reducer F6.3 - 2x Celestron connecting plates for Celestron scopes (I bought a skinnier one for Heq5 which is already included but giving away these as well) - Bobs knobs installed for easy collimation - SBC2000 live camera with focal reducer and correct adaptor to mount to a 1.25 telescope - Canon DSLR 450D unmodded (body only) + T-adapter to connect to the telescope All the above for the bargain price of £599. Heq5 pro + tripod (picture not included) + skywatcher pillar for heq5 pro + handset + eqmod cable: £499 If buying altogether: £999 would do. The telescope is ready to be posted, however I am looking to find a way to post the tripod and pillar + Heq5 mount. If I can't you will have to pick it up from Manchester. If you buy it all, then I can definitely look into posting the heq5 pro bundle as well. Postage cost would be separate to the final cost. I will calculate and inform you upon agreement of sale. Only thing to point out is, the Heq5's knob to let go of the weight's bar is broken and you need to use a plas to turn it. In my case, I just left it extended and tightened at all times as it's just used for weights. The knob got broken not due to a fall but because the HEQ5 prior to being hosted in my observatory was placed underneath a storage bed and the awkward position caught the plastic knob and eventually broke it. Moreover, the C8 has collected some dust over time but this hasn't affected the viewing experience so I chose to not fiddle with internal cleaning. Pictures: Thanks for looking.
  3. Hi mate, It is this shed on sale on Ebay: https://www.ebay.co.uk/itm/788-Refurbished-Yardmaster-Metal-Garden-Store-Max-Size-6-6W-x-3-11D-x-4-4-High-/292506175036?clk_rvr_id=1496978973556&utm_medium=cpc&utm_source=twenga&utm_campaign=twenga&utm_param=eyJlcyI6MCwicyI6OTcyMDIzNywiY2kiOiIwMzgwYzA0MTZmNTBjZGRkNTYzZGQ2NmVjODU1Y2Y5OCIsImkiOiIyOTI1MDYxNzUwMzYiLCJ0cyI6MTUyMzUyNTg2NywidiI6Mywic28iOjE1MDAsImMiOjEzOTk1Nn0%3D&rmvSB=true I bought a refurbished shed as well. However, In hindsight, I wish I had bought a bigger shed that is taller as well. This does the job and I have a table on the side where I sit and control things but a bigger shed (as in bigger than 6 x 4, maybe 6x6 or more) would have helped in observing sessions.
  4. Thanks guys. I used a C8 to capture this. Clear skies!
  5. Thanks for the info Barkis. I was wondering the same thing. With Uranus only recently passed opposition, I had expected a normal full circle. Also, in the 10mm eye piece it didn't resolve to a complete disk but more of a slighltly oval shape very small to detect. Only when I took the image it became clear that it might be going through a phase.
  6. I have yes as I didn't see much loss in pixels upon cropping at first. But that was pre-processing. It was pretty decent at 10mm eyepiece projection already compared to the tiny dot when seen from the eyepiece itself. Unfortunately, I didn't expect much from the image at 10mm as it had a haze around it so took 100+ images at 25mm instead when it just looked like a small dot still better than prime focus. This is just 1x sub post processed at 10mm. The disk became apparent during post processing. Wish I had taken a lot more subs. I intend to image uranus again at 10mm but take loads of subs to stack in registax6. I can't take a video from my 450D so this is what I am confined to. Thanks.
  7. Amazing! I wish I could get images like this one day!!
  8. Hi Guys, My first attempt at Uranus. Used 10mm eye piece projection method to capture this shot, 0.5sec sub at ISO1600. Many lessons were learnt in the end and now looking forward to imaging again next time with better planning/foresight. Enjoy
  9. I just tried processing the single frame in adobe lightroom and very pleased with the result! you can actually make out some ongoing storm movement. See below.
  10. C8 with eyepiece projection on canon 450D. In the picture where Uranus is a dot, I have used 25mm eye piece and where is is slightly bigger, I have used a 10mm eye piece. The zoomed in picture is the one taken from the 10mm eye piece which made me realise what was possible had I taken 100 or so subs at 10mm eye piece projection and stacked them together along with some dark frames to remove noise.
  11. Hi guys, Thanks for your advise. Yes so the laptop always crashed occasionally but the mount always worked when it would start again. This time, it crashed and now the mount doesn't connect at all. The mount is fine as it works with the hand controller. Anyway, time for update of night number 3: For starters I can't believe I am writing this! Three clear nights in a row. I know this will never happen again until maybe decades later. But I finished work and went straight to the observatory, didn't even enter home (i know dedication ). Anyway, I didn't want to image any DSOs without guiding/mount control as the object moves fast without guiding and with no telescope control this would have meant me manually bringing the object back in centre. I intend to buy a new laptop and fix this issue for good. With that said, I homed in on some visual observing and this is where the setup comes to life, open roll of roof, turn heq5 on, quick 3 star align and I was looking at andromeda, no hassle! Looked at andromeda, then moved to double cluster which is always a treat to the eye. Then before I could slew into more targets, the imaging bug bit me again. I pointed the scope towards uranus and looked at it through 25mm and then 10mm eye piece. At 10mm eyepiece, it looked like a small tiny disk and was clear enough but no colour. This was at 2000m focal length, F10 on the C8. I tried using my 6mm eyepiece and it couldn't resolve it to a clear disk. This is where I decided to test my eyepiece projection kit I bought 4 years ago but never used. Tried the 25mm eyepiece and uranus was visible on the DSLR. Tried the 10mm eyepiece and it was much bigger but didn't resolve to a clear disk. Took over 100 subs at ISO1600 0.5sec each on 25mm eyepiece. Then tried to take some zoomed in pictures of the moon using eyepiece projection but it wasn't very rewarding so decided to call it a night. Later on when looking at images, I felt gutted when I did a quick process on the picture obtained using 10mm eyepiece projection. Uranus was quite big and a lot of detail could easily be taken out post processing. I couldn't carry on using 10mm eyepiece because it was too difficult to keep uranus in centre and eventually I lost it completely and couldn't centre it again. This is where guiding would have helped massively as it would have kept uranus in centre as the FOV becomes very tight at 10mm eyepiece projection. I also wish I had not used ISO1600 as the noise was quite bad and also should have taken some dark frames. Attached is a picture of uranus with mild processing of 1x raw sub at ISO1600 and 10mm eyepiece projection. Uranus is definitely the target I will image next but will try ISO200 with longer exposure and 10mm projection along with dark frames to hopefully bring a better end result. Any thing you feel needs pointing out please feel free to let me know. Clear Skies.
  12. Hi again, I had the most frustrating night of my life last night. Second clear night in a row and I wanted to make the most of it to correct things pointed out in this thread like bad focus etc etc and attempt the double cluster again. however, I tried to connect the laptop to the mount and the laptop crashed. It crashed due to EQDIR cable I know this by now. I rebooted and it crashed again upon successfully connecting to the mount. Upon the next reboot, eqmod refused to work and threw a 55 file already in use error. I rebooted multiple times but the error never went. I had to remove EQMOD and ASCOM completely. Reinstalled and had the same problem. I looked online and found some files to delete namely EQMOD.ini and joystick.ini and other files in c:/users/<pc name>/AppData/Roaming/EQMOD. If you get the 66 error than that means you need to delete joystick.ini and other files too. That said, now eqmod finally opened up but refused to connect to the mount. I removed eqmod and ascom again and it still didnt connect. By this time, I had been trying to get the laptop to connect to the mount for hours and the observatory had turned into an igloo, I could see ice built everywhere! The wooden frame, the telescope's cap, it was freezing cold, chilling to the bone! I got soo fed up, and determined to make something out of the night, I just connected the handset and pointed to the moon, took some pictures and called it a day. Attached is the processed picture of the moon, 100 subs at 1/400sec aligned in PIPP stacked in Registax6. DSO imaging is not for the faint hearted!
  13. This is where I thought if I have an observatory, scope polar aligned and balanced at all times, all wires connected and a dedicated laptop at the obsy, it should be roll off roof and off you go into image land situation. Boy was I wrong!!!
  14. Thanks for the advise everyone! I had a rough rough night! I had decided to image Andromeda for an hour and then move on to M33. Double cluster I was going to image the next say. So I have an observatory i have just built and proper DSO imaging only kicked off last night with the setup working. Here's the summary: Roll off roof and get the setup ready and perform star alignment. Old laptop dedicated at the observatory crashed, upon reboot had to wait for windows updates!!! Anyway, upon reboot I got alignment going again and once star was centered, hovered on to andromeda and started imaging. Tried 60 seconds, 120 seconds etc and decided to settle for 90 seconds, don't know just instincts said 90 seconds at ISO800. Decided to take darks in the end. PHD guiding didn't work for what felt like forever! In the end had to change calibration ms to 3000! and then it worked but it took about 3-4 minutes before guiding kicked in. Decided to take 40 lights at 91s ISO800, went to hangout with my daughter came back in between and was shocked to see PHD had given up on me and had lost the star, which by now had moved up! Andromeda wasn't centered anymore which let me to try to re-centre it. Since it was on dead zenith, as soon as I pressed CTRL+1, the scope did a full 360 degree on me to reach andromeda. It never found it, very weird. I went back to the observatory (I remotely control my obsy laptop using team viewer), and was trying to work things around when the laptop died on me again! Had to do ALL the setup work all over again including guiding! looked at the 0.63 focal reducer and it had gone misty, brought my wife's hair dryer and gave it a clean. Removed the dew shield and removed the dew on the corrector plate of the C8 as well. Back to imaging and still can't find andromeda. Tried M33, can't find it either. So decided to look for double cluster. Found it upon first attempt so go to was working! Anyway, took 20 snaps of double cluster at ISO800. Then decided to call it a day and closed the roof of the obsy, turned everything off apart from the laptop and camera to take dark frames. After 6 dark frames the camera disconnected only to intermittently connect back. Didn't have the courage to go out again and reset it. Will attempt things again tonight. Imaging is soo much more tougher than visual observing!!! Lessons learnt: Need a new laptop! C8 with focal reducer isn't good for imaging large DSOs at all. The stars vignette quite badly towards the edges. Also, you don't get a full image anyway, there is this circle in the image caused by the long T-ring+LP filter when using the 1.25 tube instead of 2". As planned before, when I was building the observatory after discussions on this forum with other people, I might have to buy a refractor to mount on top of the C8 earlier than I thought. Possibly the new WO61. Attached are raw image files of Double Cluster and Andromeda at 91sec ISO800. Thanks for reading, any thing you could advise me on, please feel free to comment. Clear skies.
