Venus, false color

Using the same gear as yesterday, the N150/750, the motorized filter wheel, the green and Calcium K line filters and the cooled ASI 178MM, all guided by the soapbox, I imaged Venus.

Venus, false color

Again, nothing new, same old gear, but I replaced the red/infrared filters because I suspect that my barlow lens is not permorming well with the wide band filters. So this time, green is the new orange, and the Calcium K line remained, as I like it better than the Venus U, at least for this setup.

N150/750 on the modded EQ3, the soapbox autoguider, ASI 178 MM with cooling added. I was looking at the amount of boxes I put together, and it’s starting to eclipse the “original” gear.

Venus, OIII + Calcium K

Nothing fancy, it’s just that my filter wheel arrived, and using the gear from an old printer, and a dc motor with a reductor box, I motorized it before even its first use. It’s still manual in the sense that there is no sensor to stop the wheel, it just goes one way or the other. Instead of the red channel, this time I used an OIII filter for the orange, and the cyan is still the Calcium K, as I like it more than the Venus U. The seeing, well, could have been better.

So the gear: N150/750 on the modded EQ3, the noszogtató autoguider, filters, ASI178MM modded (cooled)

Nothing fancy here, just using the same gear with the same settings. A slightly improved szappantartó autoguider and the knowledge that that mount is, in its current mechanical state, simply incapable of not sliding a few arc minutes from time to time, be the reason a backlash or tension building up and then being released.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
