  1. I only have old (but decent) #telescope gear. I have a decently mounted 6 inch f/5 #Newtonian for example. The mount is a motor driven but manually controlled #EQ.

    From what I'm seeing, to get to a point to get digital photos through an #AutoTrackingMount, I'd need a new electronically controlled mount, an #autoguider, and a #DigitalCamera capable of time exposures. Right?

    That would easily cost 2k or more from what I see.

    Am I seeing this right?

    Nice image. I was just reading about your scope. Sounds like a flexible package.

    I have just about the opposite type of refractor, a #60mm f/17 long (very long) focus refractor. It, like your scope, can deliver fine images, though I've only tried lunar/planetary photography. And I certainly cannot do the wide field photography you do.

    Here's a shot of #Tycho through my 60mm using a stack of around 50 frames.

    That's a terrific photo.

    I tried the #RosetteNebula with the #MicroObservatory, and barely got an image. Their photo equipment is beyond most amateur astronomers' equipment, but is old. Plus the web site allows a max of a 60 second exposure. That just isn't sufficient for that target.

    Clear atmosphere always helps. So from what I'm reading the objective lens is about 90mm in diameter?

    You did better than my #M42 effort using the publicly available #MicroObservatory 6 inch Mak-Newts.

  5. I tried for a couple of days to use the publicly available Micro Observatory to get a color image of the Andromeda galaxy. But during the times my request was enacted weather was always poor.

    So I did the next best thing and went to their image archive for the last few days and found a time when the weather was clear, and found an r, g, b set of Andromeda images. I processed and aligned the components and was able to get the following color image of M31.

    I put to you a challenge. Here's my best #ETX90 photo of Copernicus crater. Have you taken one with your 80ED? It would be interesting to compare a 90mm #Maksutov #MoonPhoto with central obstruction to a clear #aperture #80ED.

    Yes, #bygone days. I grew up in the 50s, highschool in the 60s. Grew up in a little Kansas (<300) town.

    I recall remnants of a #WoodenSidewalk between the grocery store and soda fountain store.

    I remember a couple of #HitchingRails outside the grocery store. We kids didn't know they were old hitching rails, just something to climb on.

    For a time there was also an old fashioned dry goods store, with wall shelves around the store and #CrackerBarrels.

    You need a telescope that has a motorized drive, preferably one that has an equatorial mode.

    There are a few nebula that you can get with just a piggyback mounted camera.

    Beyond that you don't need a really big telescope, 4 inch or better, but a good tracking mount. You'll need some astro-camera that can look through the telescope.

    Consider a Unistellar, expensive but all inclusive.

    Heres' a piggyback image of Cygnus.

    That's a great shot.

    Do you have some kind of auto-guider, as your tracking is spot on?

    I don't have any way to take "through the scope" star images because of tracking. When I get the urge, I sometimes use the #MicroObservatory, a publicly available collection of about 6 Mak-Newts. They will send you a raw image through email, and you must reduce it.

    A good option if you don't have astro-equipment, but have computer.

    True, perl doesn't compile down. But the regular expression processes are very fast, themselves being compiled.

    I include the PDL, PGPLOT, and TriD routines, giving fast matrix math, 2D, and 3D plotting ability.

    I use perl for sumulation and data analysis. I also use perl to do things like align and stack astro-images, like the one below of the Lunar Hyginus region captured with my NexStar 5SE.

    I cannot compete with you on small field #AstroPhotography. I have only have #PiggyBack star photography capability.

    To get your quality of images, I've used the publicly available #MicroObservatory. The half dozen or so telescopes are 6 inch Mak-Newts. One can schedule targets and get emails of raw images. I process them with a Yorick program.

    It's a solution for those lacking equipment but having computer.

    Here's my best #M15.

  12. @catherineryanhyde

    That's a very nice image of #M15. Your tracking was spot on. Can you describe the #AstroPhotography equipment used for this shot?
