I do some astrophotography for fun in my spare time. I'd like to get into doing deep sky photography. In order to do that, I need a moving mount that can keep the camera aligned with the stars for minutes to hours at a time. I'll be using (at least initially) a Canon 7D (original version) with Canon lenses rather than a telescope. I currently have a 200mm lens with 2x extender, which makes it 600mm equivalent on that body.

I'd like to know if others here have ever done this and what type of hardware they've used for the motor and mount? Prices seem to be all over the place and options vary greatly on different devices. For example, I see the following:

Sky-watcher EQM-35 - $623.00US - Seems pretty full-featured for the price, as it includes tripod, motorized mount, alignment scope, and database of astronomical objects.
Celestron Advanced VX Computerized Mount - $899.00US - Seems very similar to the above, but does not include a scope, but is ~$250 more
Orion AstroView EQ Mount & EQ-3M Motor Drive Kit - $269.99US - Like the first one, but without the scope and holds less weight, and no database of objects to look at

I get the difference in price between the first and last, but not the middle one.

In any event, curious if anyone has used any of the above or any others and what their thoughts are on the quality of different brands, and anything I should be looking for or avoiding.

Services like Facebook, Instagram, Google Photos, iCloud Photo Sharing, Flickr, SmugMug, 500px, and more are available for hosting and sharing photos online. I'm curious what service, or set of services, you you use and how you decided. Do you cross post between them, and if so what strategy do you use?

I'm currently spread a bit and without much cross-posting between Facebook, Instagram, and Flickr. Not a strong conscious decision, though I've been wanting to do a bit more photography and would like to figure out a better strategy.

I think some key points to consider are cost (free vs pro, ease of upgrade/downgrade), storage space and restrictions (total space, max individual size, filetypes, enforced resizing/compression), ease and control of sharing publicly or privately, network audience and reach, and creative rights (who owns what rights on the content)

This Terms of Service; Didn't Read site can be helpful for at least determining what the general rights on these services are with some broad judgement.

I've been trying to get back into photography and love seeing what other photographers are using.

My daily driver is a Nikon D5600 with the kit 18-55mm lens, as well as a 70-300mm lens. Nothing to spectacular, but it gets the job done. I'm just a hobbyist, so I don't have any real professional-grade equipment, but hopefully with time I'll get some more stuff as I get better with what I already have.

What are you using?
