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 am a new amateur astronomer, but absolutely loving it and am fascinated by everything I am seeing and learning. I read about sketching the views in my telescope some time ago, but I never really felt that interested. However, as I learn more and get more time at the scope, I am quickly seeing the benefits and how rewarding sketching can be. I just got my first sketching kit, I have a notebook, and I also have printed some blank sketch templates. As the moon is getting so big in the sky, I think I will make some of my first sketches in the near future of the moon (as soon as this rain stops, geez!).
My question to those veteran sketchers out there is this: if you could give one or two pieces of advice to a beginner, what would they be? I have watched some sketching videos and read some articles, and am not looking for "How to sketch" advice so much as I am looking for advice on some nuances that might just make life easier. What would you tell somebody who has never put pencils to paper? Does anything come to mind?
P.S.-- I really love looking at the new sketch posts, thanks to everyone who puts their time and effort into sharing those!
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):
