    Default lx200 8" dslr advise



    I am looking to get started in ap with a dslr. I have scoped out several used canon 450d's and 1000d's in the local used market. Would love a 500d for video but i tend to live on the frugal side of life. My question is this, I know i need a t adapter, focal reducer, camera adapter and guiding method. I can get a simple kit with the t adapter, reducer and cam. adapter off a friend for $80.00. I have some homemade isloation pads, and am considering buidling a pier.

    Where i am jammed up is the guiding method. I would like to stay with the 8x50 guidescope for now as to keep price down. Would an illuminated reticle and flip mirror system suffice. Any advise with regards to simplest efficient/efficaciouse setup would be appreciated. Miss Jenniferchristine, as you have a similiar setup to which I aspire I would greatly appreciate your advice. Bit confused as to autoguiding with guide scope(expensive) vs simplest effective route for beginner.

    Thanks in advance

    The simplest route is to not bother with guiding at all. Do a precise polar alignment, and then take short-ish exposures like 1-2 minutes.

    So far, I am finding that adequate. When I get good enough that the lack of guiding is holding me back, then I'll think about a guide scope and all that paraphernalia. Until then, I've got plenty to work on.

    Good advice. Probably the answer I am looking for. Thats why i post my questions here. The main reason for asking is the ap kits i have seen for sale. One comes with illuminated reticle and flip mirror. Another comes with all the above and a telextender, but i have a barlow. Just wondering if purchasing now would save me more later??? The unanswerable question!

    Keith is quite right - a decent polar alignment can be the answer to most initial problems - it's also a decent learning curve.
    I use an off axis guider - though I'm sure you could use a decent webcam and your 8x50 finder. There's some Shixin cameras that could be adapted too - they're low light CCD cameras that security systems use - not expensive - Though I haven't tried mine yet. You can go the flip mirror system but you need a lot of concentration and you'll hate it

    I thought that would be your response and puts my mind and wallet at ease. Will start with no guiding and most assuredly be back for more advice. Thanks again, this site is invaluable.

    This is very good advice, I spent a few years doing unguided work to get comfortable with AP and image processing. Once I felt comfortable taking and processing images I made the jump to guided work which didn't seem as daunting having some experience under by belt.
