    Default First Rig



    Hi everyone,

    Firstly, thanks to everyone that's welcomed me in on the 'intro yourself' forum. So, it's early days for me but here's a list of everything I'm aiming to buy for my first set up & why I'm considering them. Feel free to comment or point out anything you think I may be either (a) missing or (b) considering but shouldn't worry about in my initial stages:

    - Celestron 4SE (I was toying between this & the Celestron 130 SLT)
    - T Adapter & T Ring for my Nikon D90
    - Piggy back mount for the same cam & wider shots
    - Shade & Dew shield to protect her
    - Moon filter since that may be the first thing I visit (Not sure if this is essential, but seems useful)

    And some point after my first purchases:

    - Solar filter
    - Power Tank if I get really into this
    - Coloured/UV/IR filters & the like to spice up my pics
    - Different eye pieces (Still wrapping my head around these)
    - Carry case for the lot

    From what I've found out so far, this could be an expensive hobby but I'm used to those. I could also spend a fortune just on accessories so I think I should only grab the necessary to start with (Is that first bunch a suitable 'necessary' list?

    I only really started seriously looking into this about 2 weeks ago so I'm looking forward to replies on my half baked plans.

    Russ.

    Welcome to the astronomy forum.

    Before buying anything, read the book BACKYARD ASTRONOMER'S GUIDE. It will give you enough information for you to make a more informed decision.

    The 4SE is an excellent telescope and a good starter telescope for many people. Howeve it has several characteristics that make it not desirable for many, perhaps most, beginners.

    The best approach is to first learn astronomy then start astrophotography. It is also better to use a separate kit for viewing and photography if you can afford to do so.

    While the 4SE mount if modified can do short exposure work in the equatorial mode, it has many issues doing so. The 4SE OTA is a high focal ratio telescope and although it can be used with a focal reducer for photography, it also has many issues.

    The Celestron C6NVX is not that much more expensive if the cost of a focal reducer, adapters are considered and will give you a far superior telescope and mount for both viewing and photography.

    Hi Russ,

    Make sure that the mount can take the weight of the 4SE and your camera. You wouldn't want the combined weight to be more than about 2/3 of the rated capacity for astrophotography. Also, isn't the 4SE on an alt-az mount? If so then you would need to consider field de-rotation for long exposures.

    Kind regards,
    Euan

    Thanks for the replies both,

    Needless to say, I'm more confused again. I guess it's to be expected at this stage. It was my understanding that the 4SE has something called a 'wedge' which he's put with long exposure photography. Perhaps I have been misguided here.

    In regards to the camera on the rear of the 4SE, again, I was under the impression that the scope was made for such usage & so I did not think to consider the weight of my camera pulling downwards from the rear of the unit. I also liked the idea of the piggy back position being towards the front of the scope to avoid seeing any of the scope with shooting wide angles to view, for example, Milky Way shots.

    Still, we live & learn.

    The book, Backyard Astronomers Guide, looks very nice but with my lifestyle (Balancing work life, home life & my other primary hobby) it would probably take me the best past of a year or longer to read in full. I'm hoping to make a purchase in the coming month or two.

    @sxinias Now you've got me looking at a whole new class of scopes. Thanks for that

    It appears that the excited in me is looking at the Celestron C6 now with both the same intentions as before, looking at planets, piggy backing for stargazing shots & attachment through a T Ring & adapter for photos of the like.

    I'm particularly intrigued by the C6 SGT. But. Is this overkill? I've been interested in space, the stars & our planets for a number of years now. It's only the telescope aspect of this that's new to me. My worries are that I could work within a limited budget, but will I want more? Most likely. Or is that something I should work towards perhaps?

    Just spoke with a guy named Ed at Harrison Telescopes. Very helpful man!

    Russ.

    Russ, you are right, it does have a wedge. My mistake, sorry.

    Actually Russ I think your plan is a good one. The 4se is an excellent starter scope and is capable of some astro photography, so you will be able to get your feet wet without dropping a ton of money only to find you're not that into it. You might want to add the power tank into the must have list though, or be prepared to buy a lot of batteries!

    It's done.

    NexStar 5SE, PowerTank, T-Ring & Adapter & Moon filter. Just need to absorb the manual & wait for a clear night. About 2-3 months away I think

    Looks like I'm on board.
