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 everyone, I've got a question.
I want to upgrade the visual back on the Mak 127. The standard back on the Mak is not pleasant to work with as seen in the image. I need to get rid of this plastic thing. I purchased a mak to sct adapter when I bought the scope, I never got around to doing anything until now as I've just acquired a Baader 2.25x barlow as shown in the image.
Now, I've had a go of attaching the the Baader Barlow into the original plastic thing on the mak, it works .... but I'm not happy with the connection being made with the two locking screws, as there is still movement when the barlow, t-ring and Canon DSLR are all in the train.
I've been having a look on FLO for some work around, does anyone have some input as to whether this will work.
Mak to sct adapter-> Baader 2 inch to 1.25 reducer adapter->Baader 2.25x barlow + T ring & DSLR
Any input or a better way of securing everything is greatly appreciated!😊
Another option I've come across is this , Baader ClickLock 2"-1.25" Adapter and Baader T2 Extension Tube to bring it to 40mm when attached to the mak to sct adapter. Anyone have any experience with this?
Hope someone with more experience than I, which basically means anyone that has successfully collimated a Newtonian, can answer a couple of compound questions I have based on my first and only attempt at secondary collimation of my SkyWatcher Flextube 250.
1) All three of my secondary collimation screws were extremely snug before I did anything and I was only able to comfortably turn them counter-clockwise. Is this normal? Do I need to loosen all three screws first before I can properly start collimation? Should I be turning any screw beyond "snug"?
2) Before collimating, I placed a yellow sheet inside my OTA opposite my focuser tube and I placed a red sheet between my secondary and primary. The view this gave through my focuser tube was of a red circle surrounded by a partial yellow ring (the secondary mirror stalk blocking a portion of this yellow annulus). While independently turning each of the secondary collimation screws counter-clockwise I looked down the focuser tube (both with and without a sight tube installed) expecting to see some change in the shape of the red area (more or less circular) and/or the yellow area (less or more even thickness). I turned the screws no more that 2 complete revolutions. I did not perceive any appreciable difference in what I saw and I turned each screw back (clockwise) to their original tightness before working with another of the screws. Does it make sense that I didn't perceive any change? Should I have turned the screws more revolutions? Should I have loosened more than one at a time?
Very confused and looking for your help. Thanks
Hello guys,my 8" dob is arriving soon.
I have trouble setting my expectations
Since i have looked through my 3 " dob its hard picturing what i could see with an 8" one.i live in a light polluted city.
Can i look at any dsos directly?
How will they look like using adverted vision?
What can i expect to see?
Also which all around filter should i buy (2") to look at dsos and maybe some planets?
