	The manual has a good description of focusing and snapping your first pictures but it doesn't talk about post-processing the images in Astro FX at all. There are guides online for how to get good astronomy pictures but here are the basics. With a telescope that is aligned well and tracking accurately you have two options for good pictures. You can take long exposures to see the detail in faint objects or you can take a bunch of short exposures and stack them. If the telescope isn't tracking well the only option you have is taking a bunch of photos and stacking them. Astro FX will align and stack photos for you. After the composite photo is stacked you can use Astro FX's editing tabs or move over to Photoshop/GIMP to adjust contrast and such.

	To align the scope follow the instructions above making absolutely sure the base is level and stable. Once the telescope is mounted, power it on, wait for the GPS to sync, and choose the SkyAlign alignment option. SkyAlign uses three stars and the location given by GPS to figure out where the telescope is pointing. The first star is used by the scope to set the x-axis. The second star is used to set the y-axis and the third star is a check to make sure the first two are mapped correctly. Ideally the first two stars you pick will be low in the sky and about 90 degrees apart. The key to getting a successful alignment is making sure your stars are perfectly centered in the eyepiece. A trick for this is to get a star close to the center and then unfocus the telescope until the star is a large circle in the eyepiece. Once you do this it should be easier to get it perfectly centered. Take your time and get it right. Once you have the telescope aligned you can use either Stellarium or the handheld to select objects to view.

		+	The new camera is a Celestron Nightscape 8300. To use you will have to install the Astro FX software on a computer and start it up. Plug in the cables to their respective places. You should hear the shutter on the camera click and the cooling fan should start automatically. Sometimes the program doesn't recognize the camera right away. If you unplug and plug the usb cable back in it should recognize it. Astroimaging is much easier when using the flip mirror so you can flip back and forth between an eyepiece and the camera.

	Many of the instructions for setup are still the same but some hints for aligning the scope may be helpful. We have some new equipment too. We have a battery pack so we can take the telescope away from an outlet and we have a new camera that excels at deep sky photography.

 This is a continuation of the Observational Astronomy project during spring term of 2015. Many of the instructions for the use of the telescope are the same, however some key parts have changed or are missing. The differences will be explained, meaning anything not mentioned is the same and the instructions above can just be followed.
-The first main difference is that the eyepieces for the telescope are different. Like before you just need to attach the star diagonal that is mentioned above to the visual back (the hole on the back end of telescope). Once you put the eyepiece in the star diagonal slot, tighten the screw to fasten it to the star diagonal. Below on the left are are the two new eyepieces for the telescope, they are both Celestron with 40mm and 30mm focal lengths. On the right is an image of the proper set up of the star diagonal attached to the visual back with the eyepiece screwed in.
