I am thinking on astrophotography with a reinforced/DIY upgraded 16" travel Dob, 3-5minutes subs. Seen that the Tom O' dual axis platform does exactly that but got two problems with that: #1, price: costs more than a GEM capable to carry a 16" Newtonian (CEM60). I know there are stronger, more expensive mounts out there - anyway, 2000$+ is beyond my budget. #2, fixed latitude. The scope is a travel Dob which I intend to fly e.g. to Namibia - unfortunately I don't live South enough to be on its Northerly counterpart. Neither I want to pay TWICE the $2k+ price tag. #3, polar alignment: no polar finder, better PoleMaster no deal. In 2020 the maximum time I want to waste with PA is 5 minutes. I have two trackers meant to be used with small telepoto/standard lemses: both came with polar finders. Any recommendations? I am also open for DIY, however need a decent low-latitude design first.
Having some trouble focusing my Dobsonian. I’m seeing objects but there very blurry, I’ve collimated my telescope already, adjusted the focusing knobs (made sure the screw was loose to be able to adjust), have tired with both 25mm and 10mm 1.25 eyepieces during the day and pointing at bright objects that are far way. I’m not sure if it’s just beginners struggle and eventually I’ll get shard images, but any tips would help! Thank you.
Looking to upgrade from my current 4.5" EQ reflector to an 8" Dob. Not particularly concerned with brand and don't mind used condition provided all is in good working order. Bundled accessories are a bonus (EPs and filters especially) though not a must. Based in North Wiltshire and happy to drive to collect within reasonable distance (<1hr30).
Hello! This is my first post in a year since my initial post after joining this community. I look forward to posting and contributing more, as well as getting to know some other astronomy enthusiasts! A little bit of background: I got into astronomy during December of 2012. Today, I am the owner of a pair of Celestron 15x70 binos, as well as an Orion xt8i Dobsonian. I own multiple eyepieces, including an 8-24mm zoom eyepiece, and a variety of filters, including a 13% transmission moon filter, an ultra block narrowband filter, and a set of color filters. The only major thing I consider to still be missing from my 'arsenal' is a way of taking astrophotographs, which leads me to the purpose of today's post. I have been looking into astrophotography for some time now, and as I have a Dobsonian, the only practical type of astrophotography I can engage in (from my understanding) is Solar System Imaging. I am looking at different Solar System imagers which come with software allowing me to stack multiple frames. I emphasize that I do not have a tracking mount, or the budget/supplies to build one. I have been particularly looking at the Orion StarShoot Camera 4, the Orion StarShoot 5 MP Camera, and the Orion StarShoot USB Camera. I am wondering why the prices are so drastically different, seeing as they all appear to perform similar tasks. I'd love if someone could give me a rundown of the pros/cons of each of these cameras, or any other useful information regarding them. In addition, if there are any similar cameras that you have had a good experience with from other companies , I'd love to check them out as well! Lastly, I'd like to know if there are any other methods with which I can take astrophotos. Keep in mind that they must be applicable to an instrument without tracking capabilities. Thank you guys for all the help! I hope to get more into the community over the next couple of months! Clear Skies- Rohun
