IC5146 updated

Finally had a chance to add some more luminance and RGB together for this final portrait of the Coccoon taken with the 305F3.8 astrograph and the QSI 583 camera.

Re: Adding a guide scope to a Meade 10" LX90 SCT

Posted By Roland Christen
A seperate guide scope won't work very well with SCTs. Differential flexure is the problem. The guide scope will keep the star centered on the guide chip, but the main scope optics will wander around on the order of many arc seconds, resulting in streaks instead of pinpoint stars.

M81, M82, NGC3077

Posted By Roland Christen
It's been kinda slow on Astromart these days, so I thought I would post a quickie image of these three springtime galaxies.

305F3.8 RH and STL11K camera. 2x 20 minutes
Half size image.

Taken during very hazy conditions last night.
Scope - 305F3.8, camera STL11K

Tonight it will be clear skies, so I will try again.

M106 2nd attempt

Posted By Roland Christen
Got more data last night. Seeing was much better and transparency was very good for around here.

Approximately 7 hours of dat, 10 minute subs, 305F3.8 RH and STL11k camera. This is a reduced size image. The full resolution image shows countless faint galaxies, some of which are very small and can be seen in the area to the left and up from M106 as tiny little dots.
