Having previously got some reasonable images by mounting a smart phone to the eyepiece. I thought I would try for a more sophisticated set up.
So last night I tried to get some pictures of the moon using a Canon Eos D450 connected to a Skywatcher 130p Newtonian via a T2 connection on the eyepiece holder.
As the camera has automatic focusing built into the lens I thought I would have to adjust the focuser on the eyepiece holder to manually get a sharp image.
Basically the telescope acting as a manually focused lens for the camera.
But no joy, I just got a bright light which seemed to fill the camera view finder. I tried various settings on the camera, adjusting ISO and aperture etc, I also had some extention rings for the camera lens so tired fitting those to extend the focal length but no better.
I sure there are many palms being slapped against foreheads reading this but as you can tell I have no idea, although I do have some of the gear.
Any pointers and/or advise would be gratefully received.
I would like to share with you an article written by me on high-resolution solar imaging in different wavelengths. Glad that the European Physics Journal (EPJ) Web of Conferences published it. You can read it at:
You can see the different layers of the Sun in high-resolution images using different setups.
Hi there! I am seeking for advice from you good people.
I want to create a setup for stargazing which is fully automated. Ideally every process like scope calibration, guiding, tracking, focusing and taking photos should be done through WiFi, preferably from an iPad tablet.
Planetary imaging is the main purpose. I don't really care about deep space imaging.
I want the whole setup to be rather cheap, small and light, at the expense of imaging quality.
I am a total noob (used to play with an ETX-70 lots of years ago), but I really need the functionality I have described above.
I am thinking of using the bellow components and kindly request that you correct/add to the list:
1) AstroFi 102
2) A ZWO camera suitable for planetary imaging (any ideas for less than or equal to $250)
3) An auto focuser and motor drive (any ideas)
4) Smth like an ASi air device?
Is a guider necessary for planetary imaging, by the way?
Do you think I am in the right path?
I still have not been able to really comprehend the full picture. Is what I am asking for doable?
Thank you very much in advance!
I think I need help with my Photoshop settings. I've been processing my photos and been very unhappy/depressed with the results. I then realized that they looked a lot better on my phone than on my PC screen. I did some testing and I discovered that Photoshop (CS4 - both 32bit and 64bit) and the basic Windows viewer [the two things I've been using all this time to look at my images] are displaying poorer quality views of my images than other viewers or programs. (see attached images) I think I just noticed this because I just got a CMOS OSC camera and was expecting a lot better than it seemed I was getting.
Do I have something set wrong in Photoshop? I really don't want to spend the money to get Pixinsight just right now (and the time to learn it) but I need to be able to see what the image really looks like while I'm processing it.
At first I thought the problem was with my monitor, but since I do see the correct image with some programs I've concluded that the issue must be with Photoshop itself. However, I have no idea at all how to fix it.
I've uploaded two views of an early processing stage of an Andromeda photograph.
This one shows the image as seen in Gimp, Irfan View, Windows Paint, on-line, the new Windows "Photos" or on other laptops, phones, etc.
This one shows the image as seen in Photoshop or in the Windows Photo Viewer or Photo Gallery on my PC. (I used screen capture to get this but it is accurate for what I see).
As you can see above, the image I'm seeing in Photoshop has problems. The main problem I notice is that the gradients of color do not flow smoothly but are concentric areas of flat color. No depth or subtlety.
Can this be fixed and if so what do I need to adjust in Photoshop or my PC? I'm using Photoshop CS4 and this effect shows up in both the 32bit and 64 bit versions.
Any help would be appreciated.
Thanks and Clear Skies Everyone
