After installing the latest version of Stellarium and then launching the app it won't start and it is nothing but a blank white screen.

I use a Celestron Nexstar 127 SLT and I am wondering how can I be able to align my telescope to the comet so I can photograph it?

Are there any solar filters I can use to see sunspots?

I have first received a solar filter from June 2019 and another one which makes the Sun orange and still no sunspots are seen in every observation I do... Is it the solar filter or the sun?

Yesterday received a Canon EOS Rebel XTI and a CF Card and the first day I got I broke (dented) the CF card reader pins, later on the camera stopped working after attempting to recharge the batteries, I was able to turn on the camera but the lcd screen won't display and won't take photos and when I turn it off the green light was still on... Please help me get this into repair!

Is the Canon EOS Rebel XT good for deepsky imaging?

I have obtained a ZWO ASI120MC-S on christmas for planetary imaging and I am wondering if this is good for guiding deepsky objects for smaller telescopes.

I guess I will just stick with the SA, I think that the more polar aligned it is and the less error it has the better the alignment?

Is this a good mount? The name of it is called Sky-Watcher EQ5 Mount and Tripod.

Is there a way to find another RA and DEC axis mount that costs around 240 pounds.

I am planning to astrophotography deepsky in the future, I have recently ordered a Canon EOS Rebel XSi. I am planning to get a Sky-watcher 72ED wiwth a iOptron Skytracker with an equatorial mount.

What I mean is the number of the ISO. Ex: ISO 1600 I am planning to use Canon by the way.

How high does my ISO need to be. and the shutter speed for Bias

What about lights?

How do I make light frames, dark frames, bias frames and flat frames?

Can I polar align my Celestron Nexstar 127 SLT?

Can the iOptron mount be able to be attached to the skywatcher 72 ed?

It doesn't matter if it is either Mini or Pro Star Adventurer?

Can somebody list me the best deep-sky targets to photograph in Spring to Summer?

Is there filters too for dimmer nebulae such as Horsehead Nebula, Heart Nebula etc?

Thank you!

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.
