It's not possible to say definitively without seeing all your settings, but 1) have you inadvertently set the register settings to exclude some images? That is, the dialog for counting and ...

I suspect the linked page has been updated, since it now shows a price of $1699.

All my tracked AP has been with a regular EQ mount. So any comparison I'd make would be subject to that qualification. But when this subject comes up, I notice that mention is often made of the ...

With a proper astronomical telescope, the moon is generally considered the first and simplest astrophotography target in the night sky, not the ultimate. That telescope, however, is essentially a ...

Thank you, Roger, for this excellent article. I've been stumbling my way through RawTherapee for quite a while, and have been looking forward to your advice on its use ever since you mentioned ...

Andy, I'm not in the SA club, but always interested in the simpler options, and have a few questions: How is that auto-guider attached to the Star Adventurer? Are you using any kind of external ...

Rutger, you're obviously a braver man than I! Since I own that very telescope, I'm glad to see the steps involved. I presume you removed the primary from the mount for cleaning? I've never seen ...

The user manual for DeepSkyStacker is still online at at the old DSS site: http://deepskystacker.free.fr/english/userguide.htm The guide was prepared for the 32-bit version of the program, but I'm ...

Thanks, Rudy, that's the key. It makes me feel kind of silly that I hadn't tried that, but in the old version, I always had to draw the rectangle on the thumbnail in the stacking parameters panel. ...

When the beta version of 64-bit DeepSkyStacker was released, I noticed that the "Result" tab of the stacking settings contains a radio button for defining a custom rectangle, but it was grayed ...

Rutger, here is an article you might find of interest. it's about four years old, so I imagine some of it's outdated, but it gives summaries of several options for doing what you're considering. Al ...

They're both crop-sensors from 2012, and if either has an advantage over the other, it's probably a a minor advantage, . . . except for one feature: the 650d (T4i) has an articulating LCD; the ...

Yes, the T2i is a Canon APS-c. This image is almost the full frame, but not quite; it's more like 90%, give or take. What's missing was cropped almost entirely from the bottom and sides.

Fortunately, Chris, we don't really need to wait until winter. We just need the clouds to go away. :-x Once the monsoon is over, I can use dark sites at higher altitudes, including one at 8100 ...

That's a common problem, and a big reason that so many of us use a Bahtinov mask for focusing the telescope. The mask is an inexpensive accessory - you can even make one yourself - that creates a ...

Having staked out a position of "frugal astrophotographer" over the past few years, I like to report to the forum when I find some gear that might interest others of the same inclination. Several ...

Now, THAT 's impressive! Please add me to the list of those eagerly anticipating your write-up on a RawTherapee workflow.

It looks to me like you already have usable gear. Your real problem will be getting to dark sites without a car. So what you can do may depend on how far you're willing to pedal that bike. Your ...

I've used three Canon DSLRs with telescopes, all just using metal T-rings. None of them has required any menu setting to operate that way. How are you connecting the camera and telescope?

I wish to second what Tareq is doing and saying here. Don't let the naysayers get you too discouraged. It's true that astrophotography can be a financial black hole, but it's also not impossible ...
