I dabbled with CMOS on earlier offerings but until this new breed of SONY BSI chips came out I much preferred CCD. You are correct, these new cameras are absolutely amazing. Especially good for me

Roland, You’re pretty good at this… 😁 Pete

Problem with short sub-exposure times and capturing many subs with full frame Sony IMX-455 sensors is hard disk space (each binned 1x1 image is 120MBytes). I know hard disks are cheap but stacking

I agree. It could have been worse. I could have had only 15 minutes. These Sony chips are amazing. Rolando

Shot this the other night after dusk. Went inside to do some work. Came back out half hour later to find clouds had rolled in. I was lucky to get 3 exposures which could be Median combined in MaximDL.

Tip-Tilt systems are available, and have been for many years. I'm not sure why they never caught on, but maybe the added expense and complexity is just not worth it. For me the latest CMOS cameras

The only reason is a communication error, possibly caused by an insufficient timeout duration. Try increasing the timeout. Using an underpowered CPU or a remote desktop connection with insufficient

Hi Brian. This is a picture of my MACH2, with Takahashi 180ED, taken this last winter near Tombstone, AZ. I was actually taking a picture of some Havilina’s that startled me during a AP session. I

I am using APCC w AP1200/CP4. Every month or two, i get 'failure to get "lat/long from mount" when starting up APCC. mount power has been on for 10's of minutes before starting APCC. i am running an

Hello All, This is an interesting discussion. I have not read all detail posting but what is the expert community sense on using parallel-plate tip-tilt star guiders? (Formerly called AO devices. But

There is an observable benefit to imaging unguided. Whether portable or not. I'm not sure why portable is being used to trump the benefits others have mentioned. I image in my backyard, like many do,

Well, with my imaging setups [scope and camera combos] the benefit is simplified setup [no guiding apparatus], simplified operation [literally point and shoot after a <30 minute point mapping run],

Thanks Ray. It would be great to have that option in order to compare and analyze results from different runs/solvers.

Hi, This is one of my images shot last August. This is an HaLRGB image of Bubble Nebula region I took with my QHY600 CMOS camera using my APM107/700 scope mounted on my Mach1GTO mount.

Quoting Dean, but also for other comments pushing for unguided imaging for portable setup: For shorter focal length, there is, actually, no observable benefit to unguided imaging for a mobile setup.

Dan, That is a awesome image, very well done. Mike

Certainly there are situations where imaging unguided with a mobile setup isn't an option. I was responding to the observations from a couple of other contributors that there is no benefit to high

Lots of little galaxies, and great resolution. Rolando
