Adding Ha data to OSC data.

Hi

I have data on M81 from last night and tonight I am going to use an Ha filter with my ZWO ASI183MC Pro. Do I load both using the Compose module, if so how?

Or combine two developed images.


Thanks

For information I tracked down the source of the streaks, they are reflection artifacts from Rigel, reflected in the Skywatcher flattener!

Re: StarTools 1.6.382 alpha is big; please report any issues

When i load data (see autosave001 from getting rid of streaks topic) with the second option, the Compose button activates and cannot be switched off? Am I missing something? As of ST 1.5 , the second option uses Compose mode (e.g. processing color and luminance seperately). It is really a shortcut ...

Re: Getting rid of streaks

Ivo Nicely processed, I have some way to go with processing. :lol: As for the colour balancing; I used the smart histogram process in Sharpcap Pro then worked with APT to capture the images. Stacking was done with DSS 4.2.2. What setting would cause colour balancing? Would the colouring information ...

Re: M42 advice

No need to take any notice of this I am far from an expert as my efforts on 'Getting rid of streaks' testify; but I tend to use 'develop' after 'wipe' rather that another 'autodev'. I seem to get better results. Worth a try.

Re: Getting rid of streaks

Ivo Yes, the streaks were there when I did a stack without the calibration frames. I then re-stacked with them and without the lowest scoring frames. The streaks coincided with the position of the edge of the oag prism when I took down the equipment, i.e diagonally across the corner. I will use drop...

Getting rid of streaks

The image attached has an area of streaked colour, it could have been caused by the oag cutting across the corner of the processor, it seemed a little loose when i disassembled it. I would like to know if anything can be done with it. Ivo (or anyone) this is my first effort with my own data, I would...
