  1. Hello everyone! Im having issues regarding dew during colder nights while imaging. I’m aware of how to solve the issue of dew forming on front elements of scopes/lenses using dew heaters, however I’m also concerned with the dew that forms on my non-weatherproof DSLR body and imaging laptop. Does anyone have any suggestions on how to combat this? Thanks!
  2. Hey everyone! I’m after some pretty wide-field DSOs that can be captured with an unmodified DSLR without too much struggle (apart from the Orion Nebula.) I can push my exposures up to around 3 minutes with no major star trailing but that’s about as far as I can go. Also I’m in the Southern Hemisphere so don’t have the luxury of choosing between many relatively bright Messier objects. Your suggestions are much appreciated!
  3. Hey everyone, I know the William Optics zenithstar 61 comes with an inbuilt thermometer, but is there some kind of general rule I can follow so that I can use the thermometer to know when I should refocus? Also, since the body of the OTA is not carbon fibre, has anyone had any major issues with the scope badly shifting focus? thanks
  4. No problem! Thank you all for your help, I really appreciate it
  5. I’m purchasing the William Optics Zenithstar 61 for use with a Skywatcher EQ 3 pro mount. I figured the wide-field nature would be forgiving on my polar alignment skills while I farmiarise myself with the many factors that are at play when capturing images.
  6. Hi everyone, im about to purchase my first astrophotography rig and was wanting some opinions on the best method to capture subs. I’m looking at using backyard EOS on my laptop to control the DSLR, but would using a shutter release cable be better/easier? Thanks.
  7. Thanks for the quick replies! I own the standard 18-55mm lense. Haven’t tried any deep sky imaging with it only some really simple sky shots. Thanks Dave, looks great! Does the field flattener screw directly into the focus tube or do you need an adapter?
  8. Hello everyone, As you can probably tell I’m brand new to the community. While I’ve been passionate about space related topics for my whole life, I’ve finally taken the leap and I’m about buy a simple astrophotography rig. Ive done a fair bit of research and, like many, I’ve decided that the William Optics Zenithstar 61 APO refractor is best suited for my situation. I plan to use my canon 600D/T3i as the main imaging camera and I also plan to use the Skywatcher Star Adventurer as a tracking mount for this scope. However I have a few questions: 1: I seem to be confused about how I should connect my DSLR to the Z61. As far as I’m aware, all I need is a T-ring and the WO Flat 61 Field flattener and I should be good to go. Is that correct? 2: will I need a dovetail bar to mount the Z61 to the star adventurer? Or can I directly mount the z61 to the base of the star adventurer? (This was demonstrated by Trevor Jones from astrobackyard with his Z61 and the ioptron Skyguider Pro.) Sorry for such a long thread; I’d just hate to finally get all my gear together and find out that some gear is incompatible. Thanks for the help!
