December 28, 2018: Single Photo Astrophotos

Problem solving Astrophotos:  I took a series of images in order to stack and see the detail of the nebulocity.  Turns out, there is more detail in a single frame than the stack (using Deek Sky Stacker).  So I'm trying to figure out why stacking loses detail (I suspect its because of small errors in alignment)

December 18, 2018: Comets, Nebulae and a Galaxy

A progress report on my astrophotography adventure.   

I'm slowly overcoming obstacles.  Among them are mechanical stability, vibration control (iOptron Sky Guider Pro),  (delay shutter opening by 2 sec), equatorial mount polar alignment (in order to take longer exposures).

Here are results over the past month:
46P with the Pleiades in the upper left.   90mm Tamron 2.8 lens

46P Annotation from
46P   200 mm f2.8 lens
M31 - Andromeda Galaxy
M42, Orion Nebula

M42 annotation from

NGC 2024  (Flame Nebula) and Barnard 33 (Horsehead Nebula)  The bright star is Alnitak

Track of a geostationary satellite passing Alnilam

Artifact: Aircraft approaching Orion

Maybe artifact:  a strange object in a wide angle photo of the east
