TMB 80/480 Piggybacked on a 8" Meade LX-90 GPS with standard wedge Meade DSI IIIc with Meade F6.3 Focal Reducer + 30mm Extension (gives F4.3) and Hutech IDAS LPS-2 filter. Autoguided using LX-90 with Astro Engineering .6x reducer & DSIc with 2.5S update rate in PHD (via GPUSB & APM)
11 480S Subs, Dark subtract done on the fly in Envisage, hand picked subs, flat frame, bias calibration and stacking done in AIP4Win 2.2 for each individual LRGB channel. Calibrated channels, wavelet noise fitered, wavelet sharpened tangent stretched, registered and joined in AIP4WIN 2.2 using the join colours tool (G2V method). Final finishing in Photoshop with autolevels, red curves tweak.
Taken on 10-02-2010
Notes: Taken under very difficult and windy conditions but included here as a first comparison with between the Orion and Hutech filtes. I'll replace this if conditions improve and I can capture a better set of frames.
