Re: Sky Background Calculator and Quantum Efficiency

Hi Robin

Thanks for the response.

I will have a look at the smart histogram functionality. I have so much going on in setting up the process I almost need a checklist. I am trying to get a good spreadsheet together to give me ideal exposure times.

Regards

Stephen

Re: Sky Background Calculator and Quantum Efficiency

Hi Robin, I was wondering about what impact the moon has on the sky background calculator. Surely a full moon would have a significant impact on the calculations. I have a cousin who lives in a the darkest skies area I know and I try to take advantage of this location compared to my Bortle 5 skies. ...

Re: Sensor analysis

Hi Robin, Thanks for the response. I am using the latest downloaded version of SharpCap. The problem is when I do the second part of the sensor analysis where SharpCap drops the exposure time down below the 6 microseconds the camara has as a min exposure. I don't know if what I do to adjust the illu...

Re: Sensor analysis

I was able to start it and it was going nicely for the first part. Then when doing the second part, it complained that the needed exposure was shorter than the min exposure of the camera (QYH 163C). This took a LOT of lighting adjustment settings. I finally was able to use my LED head lamp for a lig...

Re: Sensor analysis

I discovered the problem. The (invisible to the naked eye when not zoomed in) rectangle inside the two arrows was high but had no width. After zooming in, I could see it needed to be adjusted width wise.

Sensor analysis

Greetings, I have searched on this but nothing meaningful is returned. I am trying to do Sensor Analysis on my QHY 163C and when I started the process, I moved the two little red arrows (that form some area) to another area and then started the Sensor Analysis again but it complains about "Selected ...

Re: Field of View 0.98 x 0.74

Hi Robin, Thanks for the response. I tried to see the difference in the various calculators online and they didn't produce anything of value. Changing the resolution settings did change the field of view but the same image was used at the end just a bit smaller but still showing exactly the same sta...

Field of View 0.98 x 0.74

Greetings, I recently purchased a new QHY 16200A CFW7 camera that with the supplied OAG and adapter is 2.4 mm longer than the required back focus for my reducer/flattener. I might be forced to ditch the OAG and use a finder scope. I currently use a ZWO 30F4 with a ZWO ASI 120MC-S for polar alignment...

Re: Recommendations on guide scope and camera

I thought I should update this with tonight's effort. AMAZING. It took about 5 minutes to get an excellent polar alignment that drifts a bit when adjusting my camera. So much easier than looking through the view finder with the Star Adventurer. A fair amount of money but my back and my mental health...

Re: Recommendations on guide scope and camera

As most newish houses in Australia have a back yard the size of a postage stamp, I found that when using the camera without a guide scope, the process caused some odd issues. In my favourite spot in the back yard, it seems that the camera is fascinated with my eaves. Due to the wide field of vision ...
