hi my name is eshan, im from bradford, yorkshire hope you heard of it )

first of all this fourm is amazing so much information provded by all the members "no need of any books". its wonderful community.

ok bit about my self:

born n bread in bradford my whole life, gratuated frm leeds metropolltain unviersty.

currently im full time career for my two diasably sisters but now that they have strated attending courses with support workers it free me up to contiue with my own hobbys and life.

i bought my first ever telscope in 2009 but i didnt really use it much due to the fact i was looking after my sisters, it was and sill is the celestron 130 eq md at the time of purchase it was in my buget and it seemed ok for a beagineer.

view here: AstroMaster 130EQ-MD (Motor Drive) Telescope (item #31051) / AstroMaster Series Telescopes / Telescopes / Products / Celestron.com

now that i was free i took it out of its box and statred using it, i bought 2x balow lens and i was getting amazing images of the planets, so i thought to my self why not take picture, so i strated reserching in to astrophotography via local shops, ofc youtube , fourms and i ve ordered few books.

so far i have reserched in to ccd and dslr and telescope but i relised the telescope isnt ideal for the things i want ot achive e.g long exposure, need a lot of gear e.g better star ponter, guider scope, leans, t, rings, main thing is the eq mount i cant hook any thing up to it to control it.

the 130 eq md has the CG-3 Equatorial mount with motor drive which is useless, i thought just to get the neximage ccd see here: NexImage (item #93712) / Photo & visual accessories / Accessories / Products / Celestron.com

im in delimer so guys hope u can help me

im goign to buy the canon eos 5d mark II dslr ( can use it for home and astrophotography) and currently looking for good ccd but i want a goto eq mount which replaces the CG-3. can i do this for 130 eq or do i have to buy new telescope or mount becasue im going to go evaually in to long exposure so i need to track the objects when deep space viewing.

im struggling to polar aligning the telscope.

guys i need your help on the telescope options if you can give me a list for now i will use this telescope just saving mony for the dslr than i can pratice/ perfect my skills on this telescope.

my buget for the telescope is £600 max

im also currenly looking for telscope if find anything of interset ill will ask for you advise/expertise on that telescope.

p.s

wow ddint except it to be this hard you have to do reserch in lot of areas telscope/ camras/ gear/ astrophotography/ software etc but more less i know every thing about the dslr i need to now but still learning new thing about the telescope espically about compatibility with camras so many things you have to be aware of.

any way il be waiitng for reply yours sincerly

Hi Eshan and welcome to the forum.

You might not think there is a need for books but I have to admit there are one or two that make interesting reading, especially when its cloudy! From an imaging point of view, Steve Richards "Making Every Photon Count" (First Light Optics £19.95) is a MUST purchase. It will advise you on what you need and why you need it and will in fact save you money.

Now you sound like someone who has a great deal of passion and would like to get stuck in yesterday but I am going to advise you to stop for a moment. A good imaging 'rig' as we call it starts with the mount. Unless you have got an observatory, you are going to need to set up and pack away each time you want to image which will not be a great way to secure a brilliant polar alignment and therefore the accurate tracking of objects that are typically faint and very far away. To assist with this difficulty, imagers use something called auto guiding, which helps keep the scope on its chosen target by making adjustments to the motors as the object tracks through the night sky. Now given the need to polar align accurately, the ability to adjust the motors using the guider and the need to have a mount that is big enough to carry all the gear, you will be looking at a Skywatcher HEQ5 Pro mount. It is possible to buy a slightly cheaper model (Syntrek rather than Synscan) IF you are going to connect it up to a laptop with planetarium software, but the reality is your budget will have already been used up with just this one piece of equipment and we haven't even discussed scopes, power supplies, a guider etc and any other extras you will need.

There are two other imaging alternatives. The above rig is designed for deep sky imaging which of course would provide you with the greatest number of imaging targets. One alternative is wide field imaging, in which an image of a larger part of the whole sky is taken using a DSLR on tripod using a timed exposure. The other alternative, is that you can place a webcam on any scope you like to image the planets or the moon. Here you take the best exposures and stack them using free software to construct a composite image. Tracking is not a requirement here because the objects are so bright and the exposures are collected quickly. It is faint distant deep sky objects (GSO's) like galaxies and nebula that require precise tracking which means a precise mount and a fast scope hence the expense. You will need to decide which type of imaging you want to do first and the book above will help you understand what you will need to create the kind of image that you are after.

Hope that helps

James

Welcome essa,

I would take on board the excellent advice given by James, imaging can be an expensive part of the hobby apart from the option to use a webcam on the Moon and planets. I prefer visual observing myself but am sure others will be able to give more advise on your options.

Hi Essa, the auto guider I talked about is connected to the HEQ5 Pro via a special socket or port on the mount itself. You will need the relevant circuitry inside the mount to accept the adjustments made by the auto guider. Your existing mount can not accept this facility and is generally not accurate for DSO tracking. Glad you are going to order Steve's book because it will provide you with a really good overview of how imaging works. In addition, it is worth looking at the imaging sections to read up on some of the typical questions people ask and some of the usual problems that occur. Imaging has come a long way in recent times and can be very satisfying once you have ironed out some of the wrinkles which can prove a little frustrating.

James

(p.s Probably best to direct further questions over on the Beginners Help & Advice Section)

Hi Eshan , Welcome to SGL from a fellow 'Yorkie'. You should find the Bradord AS a good crowd . Theres a good day out in Leeds coming up in November here on Saturday November 12 th 2011 Leeds Astronomical Society . A grand day out with astronomy talks and traders. I go there every year (for over 10 years now) . By the way Green Witch (North) is at Birstall now if you want to have a look and talk about telescope kit with their astronomy expert Lee . Telescopes and Binoculars from Green Witch of Cambridge, the Astronomy Specialists .
