M33 Triangulum (Oh no not another one)

Post by nexusjeep »

Hi,
Well everyone taking photos of M33 made me want to have ago so first clear night for what seems an eternity and as normal also coincided with a 91% moon tracking about 40 - 45 degrees behind the target all night prime example of murphy's law. So thought sod it will have ago anyway this is a stack of 74 x 4min exposures with 100g -10c on the ASI2600MC Pro with no filter of any kind may try one of the Optolong ones in the future.

We are in a Bortle 5 area and as stated above the 91% moon was out to try and ruin the evening :D but it worked out reasonably well, the light pollution / moon has been calibrated out in APP. The image specs + kit are listed below. As captured and cropped version, Sharpcap x64 behaved impeccably as usual and works without any of the crashes I used to get with the x32 version as Robin pointed is better due to the large Megapixel value of the new camera. AS for the ASI2600 the well depth is phenomenal and I am really excited to see how it performs on M42/M43 and the Horsehead with Alnitak in the new year.

Imaging kit : APM-LZOS 130/780 + 1.0x MR flattener, ASI2600MC-Pro+EAF
Mount : M-UNO
Guide : Skywatcher ED72Pro+0.8x reducer Altair 290M guide camera
Software: SharpCap, GSS Mount control software, PHD2, Stellarium, APP, Photoshop CS2020

Image 74 x 240s at 100g -10C / 50 Darks / 100 Flats / 100 FlatDarks / 100 Bias (Best 74 sorted by quality in APP out of 92)

cheers,
