m42 OSC

Dopo quasi 3 mesi di inattività, dovuti a maltempo e impegni di lavoro, ho finalmente testato la mia nuova ASI533MC e la Skywatcher HEQ5 presa in sostituzione di una AZ-EQ5.

Solo 14 minuti con frames da 30s. Senza file di calibrazione. Filtro IDAS D2.

Ritengo che comunque i dark siano necessari e per le prossime riprese li farò.

La differenza con un M42 ripresa fatta nel 2016 secondo me è notevole visto il divario di integrazione.

Ripresa del 27/11/2016

14 minuti contro 2h e 50 minuti (50 minuti di Ha) fatti con un ccd mono (Atik414EXm).

Ho inoltre sperimentato la guida multistar con la versione Development di PHD2 (v2.6.9dev3) e devo ammettere che funziona bene.

After almost 3 months of inactivity, due to bad weather and work commitments, I finally tested my new ASI533MC and the Skywatcher HEQ5 taken as a replacement for an AZ-EQ5.

Only 14 minutes with 30s frames. Without calibration file. IDAS D2 filter.

I think the darks are necessary anyway and for the next shoots I will do them.

The difference with an M42 shot in 2016 in my opinion is considerable, given the integration gap.

Old shot

14 minutes against 2h and 50 minutes (50 minutes of Ha) done with a mono ccd (Atik414EXm).

I have also experimented with the multistar guide with the Development version of PHD2 (v2.6.9dev3) and I must admit that it works well.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
