just got my new telescope delivered. its an 8 inch reflector with a weird looking EQ mount. iam having trouble setting up my telescope. also its hard to point at something, along with that, i see the image rotated at 200+ degrees, near to inversion.
any help? how do i proceed?
PS: any help with the setting circles would also be appreciated
I retired a few years ago and have always been interested in Astronomy and photography. While I have been a photography enthusiast for a number of years, a few years ago I purchased a small telescope - a cheap 70mm refractor - which I have used for some shots or the moon and the recent solar eclipse. I have read a bit about astrophotography and the different types and kinds of telescopes, but I am still a bit confused as to which type of telescope would provide the "best" images with regard to contrast, color and crispness. Portability is an issue, as I believe that if the telescope itself, or any of it's component parts weighing more than 30 to 40 pounds would be more than I care manage. Also a telescope that is GoTo capable is a must, as I am totally unfamiliar with locating objects in the night sky. I'm hoping to purchase a good telescope for around $2,000. I certainly would appreciate any advice or guidance as to which type of scope, or even a specific scope that you believe would be best. Thanks in advance...!
I had a bash at imaging a couple of years ago, but found that an 8inch reflector with ST80 was too big for my Celestron CG5-GT mount. The trials and tribulations of that are here : I thought I would tell you what has happened now that I have swapped the reflector for a Skywatcher Evostar ED80.
Basically, it now tracks! I am using a QHY5II- C camera in a ST80 as the autoguider. I have a Nikon 5300 attached to the ED80 and the ST80 is piggy backed. My routine is:
1. Polar align the Celestron CG5-GT mount
2. Align it using 3 stars (e.g. at the moment, Arcturus, Mizar and Deneb)
3. Using a bahtinov mask to focus.
4. On the laptop, use ASCOM to link the scopes/cameras to Cartes du Ciel and PHD (the autoguiding software)
5. Choose a guding star, spend around 60 seconds calibrating PHD.
6. Start imaging!
7. Take darks, flats (i use a white screen app on a tablet) and bias.
I know the quality is no where near what people get with cooled CCD's and filters, but I do feel I am finally making progress. This is last nights effort, before the clouds rolled in (so, 9 x 180 seconds, with UHC filter):
I'm new to the game. Bought a Celestron 102 for Christmas 6 years ago when I was in Louisiana. The winter nights usually never got colder than low 50s and were clear as a bell. I wanted to start locating and resolving binaries, but moved to Rockville MD and between the buildings and light pollution only set the scope up once. Now I'm in Washington state sorrunded by 100' cedars and clouds. I have enough distance from the trees North to see Polaris, but haven't found it yet through the glow Seattle cast through the haze. In Louisiana I had great views of Neptune, Jupiter, Venus. Last night looking just west of straight up with just my eyes I think I could see Vega fairly well. Anyhow I'm going to try to set up on my deck, but I'm worried about vibrations. The deck elevates me about 8' and gets me off a 20* grade. I have a little concrete patio but useing it it will put Polaris behind the trees and completely cut off my south and west horizon. I retire in a couple of weeks and want to spend some time learning this astronomy thing. Looking forward to learning. Oh I want to hook a camera to my MacBook. Anyhow thanks for letting me join.
