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.
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.
I have a Sky Watcher 150 PDS and a Canon 600D I use to take images.
I'm looking at purchasing a Sky-Watcher f4 Aplanatic Coma Corrector for my setup. It's as much as I can afford, but wondering if its a good choice?
One concern i have is that my scope is an f5 which this is designed for f4 but has very good reviews.
one of my friends is a little bit confused in between these scopes -
1. TS-Optics PHOTOLINE 80mm f/6 FPL53 Triplet APO - 480 mm
2. TS-Optics CF-APO 90 mm f/6 FPL55 Triplet APO Refractor - 540 mm
which will be better for imaging ? not for visual.
Which glass is better for imaging , FPL 53 or FPL 55 ? Have anyone used either of the scopes? what is the performance of each of them?
I have a redcat 51 which is my travel scope. Now i want a refractor triplet in a range 70-80mm. But i don't want to loose the focal length by using reducer [removed word] flattener. In india not many branded scopes are available. I have to choose in between WO / TS Photoline / Explore Scientific /Sky watcher . WO triplet scopes have problem that they use their own reducer [removed word] flattener in GT series. So the focal length will be decreased, which I don't want. Please advise.
