I enjoyed the discussion. I actually took the second version I did for this and combined it 25% with the first one and like it better. https://pbase.com/rchozick/image/170907173 I like the control and

What degree of polar alignment do most find workable? I find that Polemaster gets me from 30 arc seconds to one arc minute polar alignment. Shouldn’t 1 arc minute be sufficient for guiding in most cas

Thanks Stuart. I think we have had this discussion before. I do use Photometric Color Calibration in PI. I pre process in Nebulosity (I am a Mac user) then I go to PI and use SCNR to remove green, Pho

I got a few more images from my test trip for my new ASI2600 CMOS color camera. Pelican Nebula The bright stars in the Pelican got blown out and really unfixable with the shorter exposure subs so I le

Thanks Brian.

I got some images of the comet at my favorite dark sky site. I took 10-2 minute, 10-1 minute and 10-20 second images. I was surprised that the 20 second images were the best. https://pbase.com/rchozic

Thanks Ecki.

Thanks for the nice comments. I really like this camera. I can see the more subtle gradients of color from the 16 vs 14 bit. I just wish they would make one with bigger pixels. Robert

This is my first light with my new ZWO ASI2600. This is the new ZWO 16 bit OSC APS-C size sensor camera. I really like the camera. I think I will keep it. https://pbase.com/image/170897549 Robert Choz

I have a 900 and that is only 22 pounds. Maybe the 1100 is too heavy also but 42 for the Mach 2 is definitely too heavy. I could manage the Mach 1 weight but much prefer the single axis 900 weight. Ro

No stated limit. Whatever falls somewhere in between the two items. I generally do not ever pick up anything heavy. My back is not great. Robert

I have a 900 and I think the ability to split the axis for lower weight to carry makes a 900 or 1100 much more portable than the Mach 1 or 2. One of the reasons I changed from the Mach 1 to my 900 was

I just measured the new ones and old ones. The inside hole diameter is 2.5mm and the outside diameter of the plug is 7mm. I did note a bit of variance in hole size with the smallest about 2.3 and larg

I actually have only hand tightened my clutches before now and they still needed replacement. I think it can happen from temperature and age. I was going to use something like a screw extractor if thi

I just replaced the clutch plugs on my 2010 AP900 mount and wanted to describe my experience and give some pointers to possibly help someone doing it for themselves. My mount had gotten to the point w

Wes is in a smaller group of astronomers that have a group also. I thought Wes had asked our smaller group The question and just noticed that it’s the AP group. Never mind on what I said. Robert

I am not sure if any of us have CP 4s. Robert

Call George at AP. The technical support is fantastic. Robert

I really like this. Cool galaxies. Robert

Really nice images Dean. I love my FSQ106 but the only disadvantage is how often you have to focus. I use the same temperature points for focusing. I also think the Min tool in Photoshop is a great to
