After what felt like a decade my Mesu e200 was finally delivered. It is such a beautiful piece of machinery, no frills just pure functionality.
I had the counter weights manufactured locally and completed the mechanical assembly, pretty straight forward. Thanks to @Jonk, https://stargazerslounge.com/profile/37161-jonk/ for providing me with the dimensions for a 16,5kg counterweight in stainless steel. I downloaded and installed SciTech.exe plus the other bits of software to make it work. The only thing I’m still uncertain about is Carte du Ciel. I’m used to Stallerium for my Skywatcher and Celestron PWI, which I love. I guess I’ll just have to get used to CDC.
I need some assistance and would appreciate help. My mount is not going to have the luxury of a permanent pier, I have to move it off the balcony every time I’ve finished my session. I have a very limited view of the South (I’m in South Africa) and no view of the SCP. Despite this I can polar align to a high degree of accuracy with the Synscan routine embedded in the SkyWatcher EQ6R Pro hand controller. Having had a cursory glance at the help menu in the SciTech Polar Alignment tab and it appears that I will need to have a view of the Celestial Pole. Does anyone have advice please?
Here I have a quick session of NGC891. It was shot during multiple nights between targets, 1-2 hours each night. It consists of almost 6h of luminance and 40min each RGB. 120s subs.
I only shot 1/2 ROI so no larger FOV.
I think I could think of a larger and longer scope for this small targets.
The performance of the Mesu200 is unquestionable excellent, and I'm very happy with the performance I get from mine with a 10" Quattro riding on top. It performs very well handling a pixelresolution of 0.94" (camera resolution not the RMS which is much better of course).
Planning for a future permanent setup under excellent seeing, I wonder if there are any users who has experience regarding the upper limit of the Mesu200 for photographic use.
It's tempting to try with a large newton astrograph, but wonder how it would handle a weight close to 60 kg and 0.5" pixel resolution. Common sense tells me to aim for less and not go beyond 40 Kg/1600 mm focal length.
A reprocessed attempt on NGC891. The starfield was processed separately from the main galaxy in an attempt to reduce the impact of the bright red/yellow stars.
I was very happy with the amount of detail displayed in the main galaxy.
LIGHTS: L:21, R:17, G: 15, B: 17 x 600s. BIAS:100, DARKS:30, FLATS:40 all at -20C.
This is a reprocessed LRGB image was that originally submitted in the Deep Sky section. It was taken with an Esprit 150 on a GM1000HPS and has a total integration time of about 12 hours.
I was very happy with the amount of details resolved in the main galaxy.
The starfield was processed separately from the galaxy, with the purpose of minimizing the effect of the quite bright red/yellow stars, however, I still highlighted the various small background galaxies.
