My son took a couple more w/ some processing this time. I hope you enjoy. Andromeda M31 & M32 again. This time a stack for 5 lights, 30" each at ISO 1600.  M27 Dumbell Galaxy, a stack of 3 lights, 30" eack at ISO1600.  Same M27, single shot, levels adjusted in Adobe  You can see how the stacking & processing improve the photos. We are just learning but having some fun. We were hoping to get together tonight but the weather isn't cooperating. Thanks for looking. Rich |

I see a 16 inch w/home ground reflector in your future.

One more of the Pinwheel Galaxy, 1 exposure at 30" @ iso 1600. When you'all get sick of them, let me know.  Rich |

If the exposure is 30 seconds, why use a symbol for angular measurement?

Rich #1) stack this one! woohoo!! #2) I have sincere doubt anybody here will tire of your imaging. I truly wont, ever! Rich, have you tried stacking even more? say 10 or 30 images? Are you using regi-stack? Also, have you tried the video stacking thingy for planetary stuff? |

I see a 16 inch w/home ground reflector in your future. James, don't give us any ideas, we were stretching on the 8 inch. Rich I found an 8 inch f6 reflector mirror w/mount at a salvage store when I was a kid. I ordered an eyepiece and secondary mirror from Edmund. built a box out of 1/4 plywood and made that scope work. I could see the big spot on jupiter w/it. I still have that mirror. It must be almost 2 inches thick. Full of scratches in the aluminizing, but was so big it had little effect. Looking forward to the 16  |

Rich - awesome diversion from the rocks and life. Keep on posting. Very cool you share this cosmic interest with your son. Cheers

rich, you can build a 16" for less than the cost of a commercial 8"!! You can build it shorta short for the Messier imaging or kinda long for planetary stuff. Here is a link to one super nice one.jamesp, you can have your old mirror re-silvered for almost nothing. Hell even that is DIY!! |

Yes @shotgunner Scott. Silvering not too complicated. Mirror in great shape, aluminizing not so mush scratched as it is falling away. it is a nice short focal length mirror (f5 or f6) which has a deeper dish than a long focal length, making it more of a challenge to hand grind. but fits in 5 foot tube/box. The amount of light those things grab is mind blowing. I think you divide the surface area of your pupil into the surface area of the mirror to get the light mag at 1 power. At 50 power you divide that number again by 50 to get the light gathering increase at 50 power. At 10 power it was a sniper scope, it would see in the dark. An undialated pupil is tiny. So it is a bunch of light gathering. Rich picking up those dim nebulae with 'the big eye in the sky'. with digital recording to assist, go Rich. Bet he will step it up to a 12 inch. |

If the exposure is 30 seconds, why use a symbol for angular measurement? parfive, seems liks a standard shorthand on astrobin, but I'm just learning about imaging, example cut & pasted ------ "Frames: 8x600" ISO400" Rich |

Quick question: When I was in college years ago, we attempted astro-photography with a telescope you had to manually adjust, even though it had "tracking". Are things different now? I assume a lot of it is automated.
