Hi all I’m just looking for advice on upgrading telescop. At the minute I’ve got a Meade ETX 125 and had some good views with it so far. Mainly Moon Planets and brighter clusters. However I wanted to see more Galaxies and nebulas which is a much to ask for a F15 scope.
im looking at second hand Celestron/Meade 9.25” f10 s With maybe a focal reducer and Sky-Watcher 10”-12” F4.9 dobsonians which is the better choice?
I am hoping someone might be able to help with a possible way to shoot dark and bias frames on a DSLR (canon 700D) without the need to cover the scope or camera, ideally using APT scripts
My thinking is that the camera, has a noise reduction mode where it will take the light shot, then with the shutter closed it will take a dark frame and subtract it from the light. So could you take a series of dark frames on ATP and lock the shutter down?
If anyone knows I would love to know. Would be great to automate the lights, park the scope and have it run darks and bias, without the need to go out to it and cap up at 3.-4 in the morn
Hello, I am an amateur astronomer that wants to get into deep-sky astrophotography. I already have a telescope which is Celestron Nexstar 127 SLT but it doesn't meet the requirements to take photos of wide field nebulaes/galaxies, (Ex: Orion Nebula, Andromeda Galaxy). I need some help on what to use and afford! It has to be under £550.
I need a 70 or 80mm optical tube, with a mount that does polar alignment and can be attached to the optical tube then I need a Canon camera that can take long exposure high ISO photos and last a filter or two to help reduce light pollution and contrast the nebula/galaxy more!
This is just for my birthday, I do not expect the best!
I just need a beginners setup.
Need a bit of help to narrow down what I see, I've wanted to buy a telescope a year ago but a couple of things stopped that decision.
Saw a strong bright glowing star in the cloudless sky so I picked up my old binoculars laying around. I appended three images, one what my phone saw, secondly the raw image, thirdly a star map pointing towards the object (center-ish).
I know it feels pretty laughable for s.o with an 8" GOTO + 5 yrs of experience, but maybe we can attempt to locate the object anyway ;)
To celebrate the 25th anniversary of Sir Patrick's DSO catalogue, I've added the available Caldwells to my basic Marathon search sequence.
Those interested may be pleasantly surprised by how many of the additional treasures are only a short hop from a given (or en route to the next) Messier.
The sequence for 40°N can be found at the SEDS Messier Marathon homepage or at my blog.
