  2. Hi After selling all my equipment some time ago I have now started the hobby again with a C925 on an AVX mount. Last night was my first chance to try out the Starsense Accessory, which seemed to work quite well. However I was a bit concerned that when doing the calibration for the SSA camera position and during the Polar Alignment routine the tracking seemed very jerky at higher magnifications. The video I took of Jupiter after alignment did not seem to show this (although poor in all other ways) so I don't know if the jerkiness is something to do with tracking mode used by the SSA handset during alignment. It could also be a mount fault or poor balance but I would expect that to show in the video? Has anyone else experienced this? Thanks Barry
  3. Hi all, I bought a Astromaster 130EQ two years ago and bought separately a celestron xcell barlow 2x and a Xcell LX 25mm. I now use my iphone to take photo's with a adapter. However, I have trouble finding and specially tracking objects. Will an Goto system make this much easier? The next question is, should i stay with my astromaster 130 mm newt. telescope and invest in a goto mount like the skywatcher eq5 with synscan or can i better take an Nexstar 5SE? I am open for other suggestions I want to make planetary pictures with my cannon camera (moon / mars / jupiter) if possible deep sky. However there is severe light pollution in my area. Thanks in advance
  4. Hi! Last week I received my Star Adventurer, and I'm learning how to use it. I had no issues aroud 0 - 80mm, but yesterday I was out trying to take pictures with my 200mm Takumar (300mm on my DX body), and I was struggling to point it towards my target (Andromeda). I know where it is, I could see it with my own eyes, yet, I wasn't able to point my lens towards, only after like 40 minutes... :/ I don't know how others do it, so any advice would be appreciated! What I was thinking about: 1. hot shoe adapter + phone holder + phone / tablet with stellarium, so I would see in the app where my lens pointing (adds weight) 2. some kind of hot shoe adapter + a reflex sight 3. some kind of hot shoe adapter + a green laser pointer 4. a small scope, maybe a finder scope attached to the other end of the declination unit 5. maybe it's overkill, but is it possible to make the Star Adventurer GoTo somehow? Thanks in advance!
  5. Hi all have picked out a scope and mount I'm interested in buying. The scope is the skywatcher ed80 pro and I will be using it with my canon 5d mark 1 for astrophotography. It's the mount that I'm having trouble deciding on. Have been reading loads on the net but when I find something I think will be ok I search for reviews of it and looks and behold for everyone who says this is a great choice there is someone else who says don't buy this. Anyway I liked the skywatcher heq5 mount so does anyone on here think this would be a good choice also if I bought a goto mount would this also track or would I need a motorized mount. Also does anyone have a smaller or different mouth sergestion as to what mount I should get, obviously it will have to be tracking. Cheers in advance for your reply so. Russell.
  6. This is more of a story about last nights efforts than a cry for help. I went out at ten to focus the OAG on the scope fitted with a lodestar and align the guiding axis to the telescope. The ultimate aim was to calibrate the PEC on the SS2K to start to take decent pictures with the mount. It was a glorious night. But my lodestar seems to have grown duff bright pixels by the dozen over summer. Even using full autocalibration in Maxim didn't seem to remove them. So I created a bad pixel map and applied it to my auto calibration groups but still with no effect. Meanwhile I soldiered on, using a brighter star in the OAG to focus and align axiis on. That done, I discovered there seemed to be a reflection from the bright star that Maxim insisted trying to guide on. It turned up on the row of the first bright star image and even after subsequent images when the star clearly moved according to movement calibration requests, the false star remained fixed and caused maxim to fail the tracking calibration. An hour and a half of this I tried, with various combinations of bin ratios, exposure times, star in different quadrants of the CCD and all with no success until I put the star in the top left quadrant and then calibration success! You might think that was it, I was motoring, since Maxim was now seeing the star. But no. Maxim could calibrate on the star but reported 'star faded' when trying to use it a guide star, consistently and persistently. Apparently it needs a different type of star to guide on. There were no others. So half an hour later I gave up with that and went to PhD2. It had support for the Lodestar and for the ZWI so I persevered with the Lodestar. It could even see the star Maxim refused to guide on and I could use it to calibrate the movement of the scope for Phd to guide with. I did get a 'ratio difference alert since my motion was very assymetric 'L' shaped but it did calibrate so on I went. Now I could calibrate my PEC!. Several times I achieved this, repeating it starting at different times on the worm since the ss2K will even out the measured with the already recorded. And then Puff! the star had gone - nothing to guide on and the duff pixels were there polluting the image as before. Where did it go ? The sky was still clear and the dome slot was right there where the scope needed it to be. Now I tried a few exposures at 3mins just to get a feel on what quality had resulted from all my efforts. Its an 8" 1800mm so its was optimistic but the evening conspired further - the camera intervalometer battery was flat. Not to be deterred I dug out the spare. That'll teach it. But that one has a duff lead that causes the camera to turn off occasionally and it wanted to play. It was now 1.30, I was freezing and not thinking about swapping batteries so it was time to hit the sack. Only up at 6 for work. I love these succesful evenings. Gotta have more of them. Better luck to every one else, and if you have a solution to the Maxim problem I'm interested. Mike
  7. Hi all here's my odd thought,balance now I balance the sct with the weights facing east and the scope on the left facing west But when I image the moon or Jupiter the position of the weights is over to the west and the tube is on the right facing east , So should I balance the scope with the weighs to the west ,has that's the side they will be on when I do image with a dnk21 camera tracking and PA are very good ,align master, Pat
  8. Messier 31 Andromeda Galaxy Distance from Earth - approx 2.5 million light years After spending ages getting a decent polar alignment, the clouds were on their way in so I only had a small window of opportunity remaining. This was my first real run with the new setup (minus the ST80 and ZWO ASI120 as i was having issues there) and I almost gave up. SO glad I didn't!! Focus was off a bit though I think and I've definitely over-processed EXIF: Nikon D5300 270mm f / 5.6 @ ISO 800 21 x 30 second subs Bortle 5 Stacked in Sequator. Very quick minor crop and global edits in LightRoom. No darks/flats/offsets
  9. Hello again friendly forum! Recently I upgraded from an old Vixen refractor to a Skywatcher 200 P reflector with a HEQ5 Pro mount. My first night out was pretty horrible as I couldn't even find polaris due to a mass of trees. But instead I spun the telescope around and took a variety of photos of the moon to make a huge a moasaic. So I made turned a bad night into a semi decent one (see my profile post if interested.) Finally on my second light, the moon had gone from the sky and I found polaris and I aligned my polar scope up perfectly (SUCCESS!). The last time the illuminated polar scope was so bright I couldn't see polaris through it, but this time a combination of turning the mount on and off helped me align the scope as I wanted. So I entered in all the useful coordinates/time and started the 3 star alignment process. I chose Pleiades of Tauros to the South as I could see it. So I accepted the target chosen and the mount started slewing but instead of pointing anywhere near the target, it pointed up to the west. I am very confused and still have no idea how it's happening as I've been checking the forums but I'm pretty certain I'm entering incorrect coordinates. Could somebody please help me format the location of my scope in a format the SYNSCAN will understand. Thanks for any advice! I'd love to get my setup sorted this month as I hear January is a good mont hfor astronomy, planetary-wise at least! Cheers, Tom
  10. New Celestron 8SE owner and not impressed. Alignment is a bitch. I finally "succeeded" with the three-star align and then the scope would only take me sort of close to where I wanted to go. Had to adjust manually. How spot on is alignment supposed to be? Tracking? I can't tell from the inadequate instruction manual how to engage tracking once I'm on an object. The whole exercise was supposed to allow me to do some astrophotography with my Canon 5D and related camera-to-scope attachments. Finally, I was surprised to learn (I think) that one needs to go through the alignment process for each session. The "computer" apparently doesn't hold the alignment. That right? Again, I can't find any reference in the instruction manual! If this is the case, it's certainly inconvenient. Any help or advice will be appreciated.
  11. Good Morning, Does any of the guiding softwares out there auto-correct a sync scan auto dob, with the use of a guide scope? The main use would be to to keep Planets in view so several runs of imaging them can be done in a session. I notice my XT8G does drift out of view ever 10mins at 250x. If I wanted to take gifs or many shots of something I'd need it to stay more dead on for longer than that. I have gotten as close to perfect gps coordinates, time to the second etc. Thanks Enrico
