I recently got the eq3-2 synscan mount to start with astrophotography. I first wanted to get the eq5 goto mount, but it is way out of my budget, and I could not find any good used ones that would fit my budget. Furthermore, I hear a lot of people talking about how eq3-2 is not that good for astrophotography, but what are some things I can do to improve the mount. Cheers guys.

I recently purchased my first telescope and camera, and now I want to make sure I have the correct Barlow or reducer to couple them together to achieve Nyquist sampling on the camera (or slight over-sampling). In case it’s important, I’m interested in planetary imaging—in theory that shouldn’t matter for this sampling question, but maybe there are other considerations to take into account.
I used this calculator (https://astronomy.tools/calculators/ccd_suitability) and plugged in my info:
Telescope: Celestron 8 SE
Camera: ZWO ASI462MC
Seeing: experimented with this one, but would like to get optics that allow for poor or very poor
Binning: prefer 1x1 to preserve spatial resolution, but could consider higher if SNR is a problem
I’ve seen on several forum posts that people often use a 2x Barlow to couple the two. However, according to this calculator, that will always lead to over-sampling. If anything, it says I should use no intermediate optics or even a reducer.
So my questions are:
Binning: Will I be able to see anything with 1x1 binning, or should I expect to need to bin to collect enough light?
Is there some other consideration that’s more important here than achieving correct sampling? It seems like most others are over-sampling, and perhaps there’s a good reason for this. If so, is there another formula that would let me determine the appropriate optics to buy?
Thanks in advance for any help!
Not sure which section to put this in? getting started or cameras, (Mods please move if necessary)
Need a little help/advice/recommendations,
I have been away from my telescope/astrophotography for about 2 maybe 3 years, i kind of lost the mojo for it, but now looking to get back to it, So i'm looking for camera advice/help,
Previously i only ever used a DSLR for astrophotography, however i am thinking do i stick with that or do i get something different? I know there will be a learning curve with new camera setup,
My area of interest is/would be Nebulae and Galaxies,i know there is no one camera fits all kind of thing, so Nebulae would be my main interest with Galaxies coming 2nd.
My current scope is the (Older Blue Model) Sky-Watcher Evostar 80 DS-PRO ED, so with that in mind what would be a good camera to pair that with, colour or mono i'm not fussed really,
My budget for new/2nd hand camera is £700 but could maybe stretch to £800.
Any help/advice (good or bad) will be greatly appreciated.
Hi, I just published a video of how I am cleaning my filters - I thought I might do this while my telescope is back at service due to some kind of astigmatism.
How do you guys clean your filters? it seems that every dust particle finds it way to the filters just as you are done cleaning them, and to sit in a damp bathroom seems kind of a mess...
Anyway, here is the video
