The rotation will not have any issue with registration, it will pick it up, the initial adjustment of shades of gray/exposure to match will play a big role in the black level adjustment, the less adjustment the better but I tried them all and I cannot find any noticeable on drop of quality. Apologies about the small menu, was recording it via a 6K screen and adjusted pixinsight core UI larger, maybe next time I will double it

The purpose of this is when you have a wide field image that lacks the details of a larger scope therefore replacing an area with the more detailed image without seeing the border lines. I made this as simple as possible because I cannot find any tutorial for this kind of processing. Hope this helps you.

Since I am waiting for my ERF to use for my 102mm scope. I tested this on Lunt 60mm and remove the external etalon. So it comes out to a Dual stack but with quark and pressure tuned etalon. The detail is way better than adding a 4X powermate on a dual stacked Lunt.

I recently upgraded all my reducer/flattener to APEX ED .65x to bring each scope to F4.5 @464mm focal length each. Middle is the reference FOV, both sides are on an AZ saddle so it is easier to match the middle. This has been my main DSO scope for couple of years now and will be replacing the mount with CEM70 backordered and move the current CEM60 to my RC10. Absolutely no flexture on all scope. I use OAG for guiding. The advantage for tri-scope is to eliminate filter wheel. When moon is bright I utilize all 3 Ha filters then do more OIII during moonless nights. Focuser used are Boss II and optec lynx. All 3 main cameras, 1 mount, 1 guide camera and 3 focusers are all fed to the CEM60 cable management port to a single 16Ft USB2 cable. APT is used for imaging with synchronized multicamera and dithering. The scopes are covered and stays outside, setup time 15min from uncovering to imaging.

I just got the L version because the S version is for 500mm FL or below.. I use it for my RC10. Corner stars here with ASI294MM camera https://www.cloudynights.com/topic/737568-first-light-for-starizona-apex-l-ed-065x-reducer-flattener/?p=11019320

This was taken with Lunt Double Stacked Ha 60mm B1200 Pressure tuned scope and ZWO ASI174MM camera. Cheers

I got tired of it and intended to put at least 50hrs of luminance but the whole week of cloudy weather and 3 ZWO ASI183MM came, so I will top for a while and will continue with all luminance again.

Thanks to all and thanks to work from home Covid thingy LOL

84 Hrs 😂

Added more to a total of 65 Hrs on OIII, very small difference and I think tonight will be my last attempt for this...

After the first night when the smoke no longer in the east coast I was able to add more for a total of about 35hrs on OIII. 571mm @F5.6 on Bortle 6. I will add more tonight and excellent seeing and transparency on the forecast. Most likely another 15hrs will be added tonight. 336 x 300s OIII 47 x 600s OIII
