I need a a really accurate,easy to use collimating tool. I have a used laser collimator but it does not fit snugly in the focuser so I feel it’s not very accurate. The idea of collimating causes me some anxiety anyway, so accurate and easy is the key! Can any of you offer any suggestions to help me out?
So, i've just begun my journey into Astronomy and subsequently have fallen into the rabbit hole of Astrophotography, as stated in the title i currently own a SkyWatcher Skyliner 200P FlexTube SynScan Dobsonian Telescope however as you may all know the dobsonian mount isn't really feasible for long exposure photographs and have started researching EQ Mounts and will most likely go with the Skywatcher HEQ5 Pro GOTO Mount & Tripod however i have seen comments about not being able to convert the FlexTube models of telescopes and was wondering if anyone here has had any success converting a SW flextube telescope to work on a EQ mount using tube rings?
Hey guys! Its me again... I know what you are thinking 😛 there is not such thing as a cheap mount for astrophotography...and i agree with you! I just want to know if there are any significantly cheap mounts (under 100 pounds) for my skywatcher heritage 130p that can give me maybe 15-30 sec exposure time max. Thanks
So guys after lots of advice reaserching and reading for the last 2 months i ve decided that i m going to either get a Skywatcher 200P(DOB) or a Skywatcher Heritage 130p(DOB)
If i get the Dobsonian i ll be using it about once or twice a week (if i have clear skies that is) i ll be taking a taxi to a semi dark sky location(atleast darker than my light polluted neighborhood) about 1.5 km away so the transportation cost will be close to nothing.I ve heard lots of great reviews about this neat 8" telescope and am tempted to buy it !(its going to be for visual i am aware of the earth's rotation)
On the other hand the Smaller more portable Version the Heritage 130p is a very neat telescope for its price(i ve heard) Its half the price of the 200p! I ll be taking this out almost every time i get out of the house(for walks or meetings with friends etc) I ve read part of the thread in cloudy nights and it seems like a great telescope! I ve even seen some very nice pictures with it (i know u need a mount). So what do you think guys? Should i go for the 200p or 130 p? I need the best value for money!
I just wanted to share something that I recently found out and it has worked for me like a treat!
I have a Sky-Watcher 72ED and the Field Flattener for it. I had to purchase a "special" adapter ring for my DSLR which is actually a Canon Bayonet adapter but instead of a standard T2 threads, it comes with M48 (2") threads so it will fit to the Field Flattener's M48 thread.
I have a fully screwed imaging train which makes it challenging for framing objects properly.
I was thinking of having a manual rotator in the setup so I can rotate the camera and properly frame my targets but, the issue with this scope/field flattener combination is that it does not give you enough focuser travel. By adding a rotator in the solution it would add around 10mm of back-focus meaning that i could never be able to achieve focus with the current setup.
I looked closer at my ring adapter that i purchased from FLO and it seems that it has 3 (M2.5) grub screws that seem to be holding something...
I took a screw driver and to my surprise, the grub screws are holding what seems to be a rotation ring!
I have bought some M2.5 thumb screws and presto! - I have a manual rotator built in on the ring adapter and it only costed me £3 for a set of 4 thumb screws from eBay!
I hope this post helps someone else who is looking for a manual rotator but they can't afford one (as they cost around £60) or they do not have enough focus travel with their setup.
