  1. Really lots of tech talk here. I know its important to get good alignment etc. from where I am imaging on my balcony i dont have Polaris in view and much reference stars to do a really good drift alignment (being at equator 3 degrees north). I have to take exposure subs of the brightest star i can find between 30secs to 60secs long to see where the drift goes and adjust my azimuth/altitude accordingly (this after proper leveling of mount) until i dont see any drift. Ive managed to push 90'' subs with very minimal drift noticed. Thats the drifting alignment i do now. So far it works enough for me and i get a rather decent image of M13 like below (you will still see the walking noise there) So with whatever i do and learn now until i get better and better I hope to digest the technicalities as I slowly progress on. At least i know the root cause of the problem, understanding the solution to it, and then practice it every time I do my imaging.
  2. So does this mean to manually dither in RA using this 10-20sec delay is pointless? If i dither manually in dec would it be different? Im not upgrading to guiding so soon yet. So i guess i need to do more work i guess.
  3. Hi forum. Need some advice from the seniors and pros. I just started AP for 2 months and am enjoying the process. I use a Skyrover 60ED apo with FF and a optolong moon filter. Use an unguided EQ3 goto mount. Dslr is a nikon d3100. I was imaging Centaurus A with about iso 400, 30x 45" subs. Flats biased and darks use in my image stacking with DSS. I use Gimp to do final editing. I observed lots of uni directional lines if i pull up the levels high enough. Its all across my image. Im wondering is this some kind of fault within my image train or my dslr sensor? P/s i was cleaning the filter and flattener so i wonder is this a smudge also? Any ideas or experiences to ecplain? Below is a pic sample of part of the image. Thanks much. DC
  4. Very well done. Perfect id say. Give hubble a run for its money
  5. My first DSO was also M13 This was about a month ago. SkyRover 60ED f6 Apo + field flattener + Optolong moon filter. EQ3 goto mount. Nikon D7000 unmod. ~20 x 30" ISO400. Tracking, non guiding Used DSS and Gimp to make the final image.
  6. Hello SGL. Im new in here. I just entered AP 2 months ago. Its been a great time so far. So i hope to learn more from this forum. I have a 60mm ED Apo on a SW EQ3 goto. Anyway as the title suggest, i was doing a really late long night imaging from my balcony last night. I was imaging Centaurus A with my rig set for 70 x 90" subs. While waiting i kind of dozed off till several hours later. Seeing the mount had reached its maximum RA tilt and i assume its been that for a good 2 or 3 hours with the scope right against the mount head. I quickly turned everything off. Slighlty worried. Will this cause any damage to the RA motor? It wasnt burning hot. Just warm. I have yet to inspect and test the motor. Advice please fellow senior forumers and AP gurus. Thanks a bunch.
