Eta Carina - LRGB

I was following almost step-by-step of processing LRGB images from the Starizona - Guide to ccd imaging, and happily managed to extract some good data from my previous Eta Carina RGB data sets.

Combined with the Luminance data, I used R(3 min), G(3 min), B(3 min).

The combined method is Median for RGB and Sigma Clip for Luminance. The SNR seems better.

A Picture Perfect Moment!

Image
While doing a 30 sec exposure of myself in front of the giant 30" Dobsonian telescope, the very bright sporadic meteor appear right on top of the Pleiades! I saw it at the corner of my eye, but since the 30 second exposure was still in progress, I had to keep my excitement to myself until the exposure is finish! I was glad it turned out nicely. I've tried to photograph meteors for several years, and this was actually my very first successful shot!   What else can I say, an upside-down Orion rising, starry nights despite the Moon still up the sky and causing shadows around the observing site, big Dobsonians to view the southern sky and a meteor passing near the Pleiades! .... a picture perfect moment! Oh yeah, this was taken during the Post-Eclipse Star Safari event, organized by 3RF AUstralia, at Coonabarabran, Australia on the weekend of 17-18 Nov 2012.

Rotating my boring flat Jupiter image into a 3D globe using WinJUPOS and vpython

Image
Recently, the sky cleared up suddenly over in my place. Which was a rarity in itself. And since Jupiter is high up in the sky passing the meridian just before midnight, I grabbed that opportunity to image it just like any other night. And then, I remember saw Micheal Philips old post about rendering Jupiter into a 3D globe and generate a fly-by video. I think I saw a tutorial somewhere in youtube, but simply couldn't find it. Either it has been removed, or I was just imagining it.. syyyy.. Luckily nowadays we have a new friend, ChatGPT to help with the research. after a lot of wrong prompts and refining the scope, I finally found a way.  So here it is Step - 1 (Summary). Generate the complete processed Jupiter photos as usual, using Autostakkert, Winjupos. I used imppg for sharpening (seems to be working much better than PixInsight! ), and back and forth to PixInsight for color balance and other cosmetic stuffs. Step - 2. (Winjupos) Open back the final TIF in Winjupos. Do Image Mea...

HEQ5 and Skymap Pro Connection Test

Objective: Finalize all connection software and hardware between each component is running smoothly. 1. Connection HEQ5 to Skymap Pro 8 Connect RJ45-serial cable from HEQ5 handpad to Serial-to-USB converter to Laptop Identify COM Port number (under My Computer>Manage>Hardware etc) In Skymap, under Telescope>Configure, select ASCOM Driver then Configure In the list, select Celestron Scope Driver, then Properties Under Scope Type, select NexStar 5i Serial Port = whatever COM Port number assigned by Windows Track Mode = Eq N Site = Current location Scope = not paying attention for this one yet. OK>OK>OK Under Skymap, select Telescope>Open Connection “Your Wish is My Command”!!
