So is there any way to do a setup that, assuming you have a Rebel T3(Canon 1100D), can do DSO astrophotography? Guiding is off the table at the budget.
OTA: Refractor (Orion ST80?)
Mount: IDK, but it has be complete with a motor drive for $300 USD if we go with the ST80.
I'm trying to do subs of 30 sec or less, maybe 45 sec to 1 min.
Hello. I recently acquired an Ocal electronic collimator for my new 130 PDS and the image I see when I connect it is the one I attach. I can't adjust the green circle in the circle created by the end of the focuser. Not even helping me with the offset of the program, whose maximum is 20. I don't know if anyone has tried this collimator with its 130PDS. But it doesn't seem normal. Any ideas? Thank you.
This weekend my Dad and I got round to making a portable, adjustable table for my Heritage 150p. I thought I'd share how it's made in case anyone might find it useful. I can't take any credit for the planning, but I did get to use a bunch of power tools, and I'm really happy with how it's turned out!
I had some old pine bed slats kicking about in the garage, and we used these to make the top, adding 3 indentations for the scope feet. There are pronged T-nuts set into the top, which the legs screw into from underneath.
The legs are made from one length of 180cm 2x2, cut into 4 (the finished height is perfect for me at 5'5 to stand and observe). They have a thread to wood thread dowel screw in the top end, and a pronged T-nut in the foot end, into which adjustable height self-levelling feet are screwed, so uneven ground isn't a problem.
The whole thing packs down flat for transport, and will fit under the boot floor in my car.
As soon as I get a dry day I'll sand and varnish it, to protect it from dew etc.
Winter is coming and I struggled the past days with dew on my Skywatcher 120ED. I have tried to use a self made isolation dew-cap around it, but not good enough (still dew)
I have browsed trough the forum and read about dew heaters vs. Dew shield, and figured out that I probably need a dew heater. The temperature here can range from minus 5 to minus 35 degrees celcius, but I dont think I’ll be using the scope when passing minus 20.
My question is, which dew heating option would handle minus 10 to minus 20 degrees celcius for my scope? I am afraid that the temperature loss will make the strips not functioning well when passing minus 10 degrees, but I might be wrong?
I guess my scooe is around 45cm circumference outside the tube.
I am using 220V with adapters to everything else, so power is not an issue.
