Hello I am wondering is there a way you can tell by using the spectral class of a star or any other way I can find out if a star has entered the horizontal branch or blue loop phase or if it’s on the hydrogen shell burning phase or if it’s on the top or bottom line of the horizontal branch or blue loop phase?

Here is something that I don’t understand if you want to reduce weight of the telescope how come people don’t use less focal length on telescopes and instead using smaller focal length eyepieces or barlows I understand that it would effect the eye relief but that wouldn’t be a big deal especially if your using a camera so what is the real reason do you lose light or something can someone please tell me?

Seriously visual has that magic in astronomy anyone can search up an image of Jupiter and see it and you don’t need a telescope for that and also visual has that magic to it. however when it comes to adaptive optics all they talk about is improving the image where even so it’s only in boring infrared. why don’t companies try to create adaptive optics for visual I understand that the isoplanatic angle is small but it is big enough to view Uranus, Neptune and few other objects. I don’t understand what are the other problems of adaptive optics for visual astronomy? can someone please tell me if adaptive optic kits on thorlabs or the MATX adaptive optics are good for visual astronomy?

Hello im wondering can the adaptive optics kits from thorlabs are they good for Visual astronomy for telescopes between 250mm-1 Meter telescopes?

But why are there no images in the visible light for uranus and neptune or the moons of Jupiter, Saturn, uranus and neptune or pluto if the isoplanatic angle is small enough for visible observing on those tiny objects why are they all in infarred?

Hello i am wondering there are 2 adaptive optics products I have my eye on that are still in development and I want to know if either of them work in the visible waveband and are they good for visual astronomy is the MATX Adaptive optics kit good for visual astronomy and do they work in the visible waveband? is the AO-2 and AO-5 adaptive optics by Don Bruns good for visual astronomy and do they work in the visible waveband? If not are there any other amateur adaptive optics in development that work in the visible waveband and are good for visual astronomy?

What I mean is because Jupiter is light around the whole disk of the planet adaptive optics can detect the atmosphere distortion around the whole disk of the planet by using the planet as a guide star and then if it is light around the whole planet then shouldn’t the adaptive optics be able to see the distortion around the whole planet?

But can’t it do the whole planet because the whole planet is bright enough for it to work?

If it only corrects a small part then why don’t you use higher magnification?

Still I can only image so much and I like to do visual Mabye the MATX adaptive optics when it comes out I wonder if planewave adaptive optics would do the trick?

I’m talking for planetary and double stars.

Hello I’m wondering if planewave adaptive optics work for viewing in the visible light spectrum and work with visual astronomy? and I’m not too sure if you have heard of the MATX team but they are developing amateur adaptive optics and I am wondering if they can be used for viewing in the visible light spectrum and work with visual astronomy?

Hello I was wondering can you reach the diffraction limit on any telescope by using the lucky imaging technique? I would think if the seeing is really bad just use a shorter exposure time so say if you had a giant telescope and your trying to image Jupiter and you can do 0.000003 milliseconds exposure that is so short that can you reach the diffraction limit on even say a 10 meter telescope in poor seeing because 0.000003 milliseconds exposure is so short that it would freeze the atmosphere?

Hello I’m wondering if adaptive optics work on visual observing or if there is something like that in development?

Hello I searched up amateur adaptive optics and I found some on Thorlabs and I am wondering if it is worth it will I be able to reach the diffraction limit with amateur adaptive optics or are they no good and don’t improve seeing?

Hello I am wondering for example if I have a super large telescope with a maximum resolving power of 0.01 arc seconds would it be possible to resolve 0.01 arc seconds of detail by stacking billions of frames to correct for seeing conditions or is that limited as well. I would think if the seeing conditions are not good just stack way more frames. so what I’m saying is no matter how bad the seeing conditions are would it be possible with a super large telescope with no adaptive optics for be able to reach the diffraction limit of 0.01 arc seconds by stacking like trillions of frames to get past the bad seeing conditions or is that limited as well?
