    Hercules is now coming into view- got this one last night- the whole field of view and a 100% crop (800/5.6, ISO 1250):

    My technique is finally good enough that I needed to program periodic error correction (PEC) on the motors; my first attempt wasn't great but I could still nearly double the exposure time (5 s to 8 s). Presumably, as I keep refining the PEC, the performance will continue to improve.

    Up to 28 minutes total exposure time- image quality and colorimetrics significantly improved:

    You know, when I came across this image all I could think is, this belongs on the OBU thread. So here are the Spanish peaks in Colorado, along with credit where credit is due. :wink:

    For the next few days, (from left to right) saturn, mars, and jupiter are all visible at night:

    And a little zoomed in (the red spot is visible):

    Tonight, 9pm- midnight, Europa is transiting Jupiter and the shadow may be visible (midnight - 3am, EST)... fingers crossed for good viewing conditions!

    the image in the previous post was better, colour wise ... you have gone back to a very green hue in this one :wink: The star sharpness in this one is much better

    You guys sure make me want a nice "Scope" :frown: I'm feeling motivated but I have a lot to learn.

    I feel exactly the same :smile:. I've been thinking about a scope for years now, but I've had other things to do, and if I get a scope I want to put it to good use. I have been very tempted by this entry level scope, which have got some pretty good reviews (e.g. it won the comparison with other scopes here: http://telescopes.toptenreviews.com/telescopes-for-beginners-review/celestron-cosmos-review.html [Broken])...
    And a clip here:

    I can speak from experience- people here are excellent resources for learning this stuff. Go for it!

    Another investment opportunity missed. :frown:
    http://www.celestron.com/browse-shop/astronomy/telescopes/cosmos-90gt-wifi-telescope $400.00 US
    http://telescopes.toptenreviews.com/telescopes-for-beginners-review/celestron-cosmos-review.html -Discontinued
    Amazon $670.47 US

    That would be a nice starter. :thumbup:

    Now that I have PEC working fairly well, I'm able to acquire many more useful images- here's 40 minutes total integration time, with fairly strict thresholds for image acceptability based on DSS 'score' and 'FWHM':

    A small section of the total field, showing NGC 6207:
    40mRGB_zpso8jqqzug.jpg

    And a 100% crop, cranking up the saturation ('cuz I can...)

    Thanks to davenn for helpful hints...
