I bought a new one, I tried. It rocks in all directions. in addition, the wire of the cross fell out and was lost I made my own cap, no reduction. I don't know if I'm doing it right. I'm a goddamn perfectionist ...

Hi. I wanted to set up the secondary mirror using a webcam, but something is probably wrong. I think it's a focuser/draw tube (I'm not sure about the nomenclature). Are there any ways to fine tune this?

Hello. Recently, my mount has been working with resistance in both axes. As far as I have tweaked the DEC, I have a problem with the RA. I just can't match these items. If I hadn't taken the assembly apart myself, I wouldn't have believed that these parts fit. Has anyone had a similar problem? Any suggestions?

You have very advanced setups. Asiair and astrohubs are dropping out for now. But my friend is supposed to make a hub for me and I think I'll think about 3D printing a handle for this.

Hi! I'm mature for a serious approach to guiding. Narrowband requires long exposure times, and properly arranged cables can make it easier. Exactly, properly arranged cables, but how? At the moment, I combined 3 cables into one (guider, dslr, dslr battery). The heaters have usb inputs so I decided to connect them with a hub and lead them out with one cable. I don't know where to attach the hub yet, but it will be rather on telescope. Maybe someone will show their setup and cable management methods? I will be grateful. Best regards

I have dilemma. The Sbig ST-2000XM seems to be outdated. However, I live in a city so I have a lot of light pollution. Supposedly, mono cameras are better in such conditions? I wonder if it is worth using such a budget solution at the beginning? I am currently using a Canon 600D with astromod.

Unfortunately, Nikon does not support BULB mode on the computer. I had the same problem with my D5100. The intervalometer is necessary for longer exposure times. In less than 30 seconds, there is little point in guiding. Although it is worth training in guiding to make it easier in the future. Edit: what about reducer/flattener?

I found it. But I have considerable gaps in knowledge. After graduation, I have to work hard on the theoretical foundations of astrophotography. Excel show to set APT to 2

I'll try next clear night. Thank you gentlemens.

And leave dither scale 10 in phd2?

I think only one filter has been removed. It is not a full spectrum mod. I received one filter as a souvenir, and the person who made the modifications thinks that there is no need to remove two filters. But soon the Moon comes into play, and so far I'm not using filters. Besides, I might have a problem with that. SkyWatcher is smart . Their reducer does not support filters 😅 I'll try to increase the dithering. I just don't understand these calculations. If I have a 1.3x scale difference (image / guide scale). In phd2 I have dither scale set to 10. In APT I have set to 1. So that's 13 pixels. If I change dither distance to 2 in APT, I will get an offset of 26 pixels. Setting APT dither to 7 will give me over 70 pixels. Am I counting something wrong? There is any "sweet point" how many pixels should I set for dithering?

a single light frame a single bias frame master bias final stack Hope everything works.

Thanks. I used the latest version of Siril. A few days ago it was published and I can see that the RCD is set by default. Damn white nights. Terribly short, but now the moon is coming, it will be a bit of a rest. I'm seriously starting to think about a cooled camera, I have to look for information that is worth choosing at the beginning. I just wonder if this noise on the red channel is normal? Single light frame, auto stretch.

Do you mean dithering distance in APT? I didn't change much in apt. Only time, because sometimes the mount goes crazy
